Furthermore, studies using obese Zucker rats demon strated that the CB1 inverse agonist, rimonabant, ame liorated proteinuria in an animal model of obesity induced nephropathy.Treatment with rimonabant partially restored creatinine clearance, reduced glomeru losclerosis and tubular-interstitial fibrosis, and lowered tubular damage and renal hypertrophy.It should also be noted that these findings may have been mediated by the effects of rimonabant and not related to the EC system. While obesity in fa/fa Zucker rats is caused by a mutation of the leptin receptor, rimonabant acts to increase leptin uptake by the kidney, which has been shown to reduce proximal tubule metabolic activity.Therefore, improvement in renal function in these rats may have occurred due to mechanisms related to leptin’s role in proximal tubule cell metabolism,as opposed to a direct action on the EC system. Using a novel mouse strain lacking CB1 receptors in renal proximal tubule cells, Udi et al.found that CB1 receptor deletion did not protect the mice from the deleterious metabolic effects associated with obesity, but significantly diminished obesity-induced lipid accumulation in the kidney. Furthermore, the stimulation of CB1 receptors in renal proximal tubule cells was found to be associated with decreased activation of liver kinase B1 and decreased activity of AMP-activated protein kinase, as well as reduced fatty acid beta-oxidation.These findings indicate a potential relationship between renal proximal tubular epithelial cell CB1 receptor and the pathologic effects of obesity-induced renal lipotoxic ity and nephropathy. In summary, the findings related to the CB1 receptor highlight its partial potential in acting as a therapeutic target for obesity-induced renal disease. Further studies are needed to ascertain the efficacy of modulating CB1 in the kidney to improve renal dysfunction independent of its effects on weight.

The CB1 receptor has been shown to be upregulated in other renal disorders marked by interstitial inflammation and fibrosis,vertical hydroponic system including acute interstitial nephritis.Using unilateral ureteral obstruction as an ex perimental model for renal fibrosis in mice, Lecru et al.showed that CB1 receptor expression was upre gulated in UUO animals compared with controls.Treatment of UUO mice with rimonabant reduced monocyte chemoattractant protein-1 synthesis and decreased macrophage infiltration.It was also shown that CB1 receptor activation led to enhanced VEGF levels, which subsequently reduced nephrin expression and protein levels.There is accumulating evidence indicating the important role of CB1 and CB2 receptors and their modulation in the pathogenesis of various forms of AKI. With regard to ischemic AKI, selective CB1 and CB2 receptor agonists were found to have a dose-dependent effect in preventing tubular damage following renal ischemia/reperfusion in jury in mouse kidney.In a separate study, however, the administration of cannabidiol, a non-psychoactive constituent of cannabis with poorly defined pharmacological properties, led to a reduction in renal tubular injury in rats following bilateral renal ischemia/reperfusion.Cannabidiol significantly attenuated the elevation of serum creatinine and renal malondialdehyde and nitric oxide levels associated with this condition.In a more recent study, a triazolopyrimidine-derived CB2 receptor agonist was demonstrated to play a protective role in inflammatory renal injury following bilateral kidney ischemia/reperfusion.A series of studies have demonstrated the deleterious role of CB1 and the protective effects of CB2 activationon a nephrotoxic model of AKI in cisplatin-induced renal injury.Inhibiting CB1 receptor or activating CB2 receptor limited oxidative stress and inflammation and reduced tubular damage in kidneys of animals with cisplatin-induced AKI. In addition, ß-Caryophyllene, a natural agonist of CB2 receptor, dose-dependently protected against the deleterious effects of cisplatin-induced nephrotoxicity.Furthermore, CB1 and CB2 receptors have been shown to play a role in renal apoptotic and inflamma tory signaling pathways.Indeed, activating CB1 receptors is known to result in enhanced expression of oxidative/nitrosative stress markers, which activate p38, MAPK, and c-Jun N-terminal kinase pathways, as well as nuclear factor kappa-light-chain-enhancer of activated B cells-dependent transcription of downstream proinflam matory target genes.

Ultimately, the activation of either route leads to apoptotic cell death and inflammation in the kidney.Conversely, CB2 receptor activation has been found to reduce proapoptotic signaling and me diate anti-inflammatory effects by attenuating immune cell infiltrates and inflammatory cytokine release.Mukhopadhyay et al. showed that a peripherally re stricted CB2 receptor agonist , in a mouse model of cisplatin-induced nephrotoxicity, dose dependently attenuated renal dysfunction as measured by serum concentrations of blood urea nitrogen and creatinine. The protective effects of CB2 receptor ac tivation in these studies were absent in CB2 receptor knockout mice, suggesting that CB2 receptors are a prom ising therapeutic target for reducing renal inflammation, oxidative/nitrosative stress, and apoptosis. Another major contributor to AKI, which is associated with significant morbidity and mortality, is sepsis associated kidney injury .In a study using a cecal ligation and puncture mouse model of sepsis, CB2 receptor knockout mice demonstrated increased mortality, lung injury, bacteremia, neutrophil recruit ment, and decreased p38 MAPK activity at the site of in fection.Treatment with a selective CB2 receptor agonist reduced the effects caused by CLP, such as inflammation, lung damage, and neutrophil recruitment, and ultimately improved survival.These findings are in line with evidence demonstrating that following CB2 localization to leukocytes, their activation has been shown to mitigate leukocyte tumor necrosis factor-a-induced endothelial cell activation, adhesion and migration of leukocytes, as well as proinflammatory modulators.Therefore, CB2 receptor modulation may represent a novel therapeutic target in the treatment of SA-AKI.The mechanism by which the cannabinoid recep tors modulate or recover tubular cell survival following acute damage are not well defined at this time. However, molecular differences in cannabinoid receptor mRNA and protein levels as well as differences in the physiological outcome of receptor activation are likely related to the type of AKI and to the abundance and lo calization of receptors. While many of the studies evaluating the role of the EC system in renal homeostasis and pathophysiology focused on CB receptors and their modulation, it is important to keep in mind that the overall effects of activation and inhibition of the EC system are dependent on various factors, only a portion of which is related to the activity of CB receptors.

For example, the chief endogenous activators of the CB receptors, AEA and 2-AG, are present in substantial concentrations in the kidney; however, physiological responses elicited by these ligands under normal or pathological conditions have not been fully elucidated. Furthermore, detailed studies on how elevated or decreased levels of these ligands may impact renal function and pathology are scarce. For example, it is well known that AEA plays a role in the modulation of renal hemodynamics.Infusion of this ligand was found to be associated with vasorelax ation of juxtamedullary afferent arterioles in vitro,in creased renal blood flow in rodents, and alteration of tubular sodium transport.While these effects may be partly mediated through the activation of CB1 and CB2 receptors, it is important to highlight that these findings indicate the total effect of this ligand and it is difficult to identify exactly which receptors are activated in each segment of the nephron. Furthermore, there are CB receptor–independent effects that are not accounted for when the role of these ligands were to be assessed only in the context of CB receptors. Recent studies have begun to address this important point by attempting to define the impact of these ligands in renal disease states. Biernacki et al.described alterations to the EC system in primary and secondary HTN, noting that these conditions resulted in renal ox idative stress through increased reactive oxygen species and diminished levels of antioxidant enzymes. Despite the enhanced activity of FAAH and MGL in primary and secondary hypertensive rats,cannabis grow set up the levels of AEA and 2-AG in the kidney were significantly in creased.Increasing endogenous levels of AEA by pharmacologically inhibiting its degradative enzyme,FAAH, with a selective FAAH inhibitor, URB597, was found to have resulted in the inhibition of ROS gener ation in both types of hypertensive rats. These effects were mediated through improvement in antioxidant defense in the primary spontaneously hypertensive rat kidney via the Nrf2 pathway, as well as through reduced proinflammatory responses in sec ondary hypertensive rats.Furthermore, URB597 augmented ROS-dependent phospholipid peroxidation products and levels of ECs in both types of hypertensive kidneys, which resulted in enhanced CB receptor expression in SHR rats and enhanced ex pression of CB2 and TRPV1 receptors in DOCA-salt rats.

Chronic treatment of Wistar normotensive con trol rats with URB597 similarly enhanced phospholipid oxidation in the kidney, comparable to its administration in DOCA-salt rats.Thus, while the EC system appears to play a protective role in HTN, the administration of a FAAH inhibitor did not significantly alter the proinflam matory or oxidative conditions caused by primary HTN, and only created imbalances between ECs, oxidants, and proinflammatory factors in secondary HTN, potentially leading to the development of kidney dysfunction. With regard to other renal conditions, such as AKI, studies have shown varied responses to kidney injury in EC expression levels. Moradi et al.demonstrated that renal ischemia/reperfusion injury is associated with a significant increase in renal 2-AG content using a bilateral ischemia/reperfusion mouse model of AKI. It was found that the augmentation of kidney 2-AG con centrations following MGL inhibitor administration resulted in improved serum BUN, creatinine, and tubular damage score; however, the mRNA gene expression of renal inflammation and oxidative stress markers was not altered. Conversely, in a cisplatin-induced nephro toxic model of AKI, cisplatin enhanced AEA but not 2- AG levels in renal tissue.To date, the mechanisms and conditions under which CB receptors are activated by ECs in the kid ney—and subsequently the signaling cascades that re sult from this activation—have not been fully described. Studies have demonstrated conflicting re sults describing the role of AEA and CB1 receptor acti vation in mediating glomerular podocyte injury. Jourdan et al.74 showed that chronic exposure of human cultured podocytes to high glucose resulted in a significant upregulation in CB1 receptor gene expres sion, which is also associated with an increase in cellu lar AEA and 2-AG. This is associated with signs of inflflammation and podocyte injury, which manifest as decreased podocin and nephrin and increased desmin gene expression.In contrast, Li et al. reported the protective functions of AEA following L-homocysteine -induced podocyte injury. AEA blocked Hcys induced NLRP3 inflflammasome activation in cultured podocytes and ameliorated podocyte dysfunction, ulti mately precluding glomerular damage.Therefore, while the former study demonstrated that an increase in CB1 receptor gene expression accompanied by an upregulation in AEA and 2-AG is associated with podocyte injury, the latter study suggests that AEA ex erts protective and anti-inflflammatory effects in podo cytes. Future studies are needed to investigate the role of EC ligands in CB receptor activation under varied conditions in renal health and disease.Among US adults in 2019, e-cigarettes were the most commonly used non-cigarette tobacco product , with use of e-cigarettes highest among adults aged 18–24 years . The convenience of newer pod like devices, the use of nicotine salts to provide higher doses of nico tine with less throat irritation , and marketing of e-cigarettes as smoking cessation aids all contribute to lower perceived harm and may account for recent increases in use among adults . Over a third of adult e-cigarette users also self-identify as current users of tobacco cigarettes , and the most common reasons given for e cigarette use are for cessation of tobacco cigarettes or health-related concerns . While smokers may use e-cigarettes to reduce their exposure to the toxic chemicals found in tobacco cigarettes , there is insufficient evidence to conclude that e-cigarettes are effective smoking cessation aids . Little is known about e-cigarette use among vulnerable populations such as those with SUDs. Among SUD treatment clients high rates of current ciga rette smoking have been reported, however, with lower rates of past 30-day e cigarette use. Similar to the general population, the majority of current e-cigarette users receiving care in SUD treatment programs are also current users of tobacco cigarettes , and many report that they use e-cigarettes to either quit or reduce cigarette smoking . These findings highlight the importance of considering cigarette smoking status to understand e cigarette use among clients in SUD treatment to inform the development of anti-vaping messages to support smoking cessation in this population. Although the studies by Gubner et al. and Baldassarri et al. examined the correlates of current e-cigarette use among patients in SUD treatment, these studies did not focus on beliefs and attitudes for using e-cigarettes as a smoking cessation aid.

Human studies examining CNS sequelae of chronic marijuana use provide evidence for increased metabolism and activation of alternate neural pathways within these regions . Further adverse effects may result from the pharmacological interaction of alcohol and marijuana, where THC has been reported to markedly enhance apoptotic properties of ethanol. In infant rats, administration of THC alone did not result in neurodegeneration; however, the combination of THC and a mildly intoxicating dose of ethanol induced significant apoptotic neuronal cell death, similar to that observed at high doses of ethanol alone . In sum, studies of adolescent alcohol and marijuana use indicate weaknesses in neuropsychological functioning in the areas of attention, speeded information processing, spatial skills, learning and memory, and complex behaviors such as planning and problem solving even after 28 days of sustained abstinence . There are also associated changes in brain structure and function that include altered prefrontal, cerebellar, and hippo campal volumes, reduced white matter microstructural integrity, and atypical brain activation patterns . There may be potential reversibility of brain structural changes with long-term abstinence , though additional studies are needed to understand the extent to which abnormalities persist or remit with time. Further, the potential interaction of alcohol and marijuana are of concern considering that comorbid use is common .It is postulated that there is an asynchronous development of reward and control systems that enhance adolescents’ responsivity to incentives and risky behaviors . Bottom-up limbic systems involved in emotional and incentive processing purportedly develop earlier than top down prefrontal systems involved in behavioral control. In situations with high emotional salience,drying cannabis the more mature limbic regions will override prefrontal regions, resulting in poor decisions.

The developmental imbalance is unique to adolescents, as children have equally immature limbic and prefrontal regions, while adults benefit from fully developed systems. Within this model, risky behaviors of adolescents is understood in light of limbic system driven choices to seek immediate gratification rather than long-term gains. Moreover, this relationship may be more pronounced in adolescents with increased emotional reactivity. Behavioral and fMRI studies show increased subcortical activation when making risky choices and less activation of prefrontal cortex, as well as immature connectivity between emotion processing and control systems overall . A more specific characterization of these patterns using comparisons of low- and high-risk gambles indicated that high-risk choices activate reward-related ventral striatum and medial prefrontal cortex, whereas low-risk choices activate control-related dorsolateral prefrontal cortex. Interestingly, activation of the ventral medial prefrontal cortex was positively associated with risk-taking propensity, whereas activation of the dorsal medial prefrontal cortex was negatively associated with risk-taking propensity , suggesting that distinct neural profiles may contribute to the inhibition or facilitation of risky behaviors.Development of effective treatments for alcohol use disorder remain a high priority area which involves screening compounds in the laboratory before proceeding to clinical trials . Within this process, there is a need to develop and understand relationships among human laboratory paradigms to assess the potential efficacy of novel AUD treatments in early-stage clinical trials. To date, reviews of the human laboratory literature in AUD pharmacotherapy development indicate significant outcome variability based on experimental paradigm parameters, population of interest, and sample size, and suggest that these myriad variables contribute to the disconnect between laboratory effect sizes and treatment outcomes . Amidst the efforts to develop translational experimental paradigms, neuroimaging tasks are increasingly used to explore potential pharmacotherapy effects on neural correlates of alcohol-induced craving . Alcohol consumption produces neuroadaptations in multiple circuits, including GABA-ergic regulation of traditional reward circuitry; alcohol craving is mediated by cortico-striatal-limbic activation, heightens relapse risk , and can be triggered through internal and external stimuli associated with alcohol consumption .

For this reason, neuroimaging techniques, such as functional magnetic resonance imaging , have been used to explore these circuits as potential medication targets. Recent qualitative reviews and meta-analyses suggested that while such fMRI tasks vary in sensory experiences and scan parameters, mesocorticolimbic areas consistently exhibit task-based neural activity and may be viable tools in understanding mechanisms of AUD pharmacotherapy . Based on this emerging literature, there is growing evidence that neural responses to alcohol cues and associated contexts are predictive of real-world consumption behavior and, potentially, clinical outcomes. For instance, among college students, alcohol cue-elicited blood oxygen level-dependent response in caudate, frontal cortex, and left insula predicted escalation to heavy drinking over a 1-year period. Further, insula and frontal gyrus activation in response to an emotion face recognition task similarly predicted alcohol related problems five years later in young adults . Regarding treatment outcomes, increased ventral striatum activation in response to alcohol cues was associated with a faster time to relapse in a sample of abstinent AUD individuals . Comparisons of AUD treatment completers and non-completers in a community sample indicated that non-completers showed stronger associations between reported alcohol craving intensity and resting state functional connectivity between striatum and insula, relative to completers . Of note, one study had contradicting results by reporting that relapsers, compared to successful alcohol abstainers and healthy controls, exhibited reduced alcohol cue-elicited activation in ventral striatum and midbrain . Several studies have examined whether AUD pharmacotherapies alter neural responses to contexts that elicit alcohol craving, including alcohol cues, exposure to reward and emotional faces, and stress exposure. While significant variability exists in sample populations, examined tasks, modified areas of activation, and molecular targets of treatments, there is some consistent evidence that AUD pharmacotherapies may reduce reward-related activation in regions such as the ventral striatum, precuneus, and anterior cingulate . Importantly, in one study of naltrexone, magnitude of reduction in alcohol cue-induced ventral striatum activation was associated with fewer instances of subsequent heavy drinking . In support, Mann and colleagues have found that individuals with high ventral striatum cue reactivity demonstrate lower relapse rates when treated with naltrexone than those with low VS reactivity. Bach and colleagues have also identified that individuals with high alcohol cue-reactivity in the left putamen exhibit longer time to relapse when treated with naltrexone, compared to those with low reactivity.

Together, these studies underscore reward circuitry as a key area in the translation of neural responses to clinical outcomes in AUD medication development . Alcohol self-administration tasks in the laboratory are thought to capture alcohol use behavior in controlled settings that approximate consumption in real world settings. Studies have tested multiple variants of self-administration paradigms,ebb flow including tasks that require participants to orally consume alcohol at the cost of monetary rewards per drink , and intravenous methods that can closely control breath alcohol concentration levels e.g. computer assisted self-infusion of ethanol.Studies have used self administration methods to test genetic, physiological, and psychological risk factors for heavy drinking .While both fMRI cue-reactivity tasks and alcohol self administration tasks are widely used in alcohol research, the extent to which cue-reactivity predicts self-administration in the laboratory remains unknown. In light of the emerging role of functional neuroimaging in predicting drinking behavior and AUD treatment outcomes, a remaining question is the nature of the relationship between neuroimaging task-induced neural activation and widely utilized laboratory paradigms considered proximal to real-world consumption, including self-administration tasks. To date, several studies have examined relationships of response across different laboratory paradigms and have consistently identified that alcohol craving during intravenous alcohol administration mediates the relationship between alcohol induced stimulatory effects and subsequent oral alcohol consumption . While relationships across human laboratory paradigms are recently delineated, no studies have yet investigated whether alcohol cue-induced BOLD response is predictive of responses within laboratory self-administration paradigms. To address this gap in the literature and to further integrate neuroimaging and human laboratory paradigms for AUD, the current study examines whether alcohol taste cue-induced ventral striatum activation predicts subsequent oral alcohol self-administration in the laboratory. These secondary analyses are conducted in a within-subjects design whereby the same participants completed an fMRI cue-reactivity task followed by an alcohol-self administration task . As striatal activation is thought to underlie craving responses , we hypothesized that those with greater ventral striatum activation would consume their first drink faster than those with lower activation. Similarly, as previous research has demonstrated that mesolimbic activity predicts real-world heavy drinking, we hypothesized that ventral striatum activation would also be positively associated with the total number of drinks consumed during the self-administration paradigm. Participants for this secondary analysis of an experimental laboratory study on naltrexone a score of 8 or higher on the Alcohol Use Disorders Identification Test AUDIT; self-identification of East Asian ethnicity lifetime non-alcohol substance use disorder clinically significant levels of alcohol withdrawal (indicated by a score of 10 or higher on the Clinical Institute Withdrawal Assessment-Revised CIWA-AR for women, pregnancy.

Interested individuals completed an in-person laboratory screening visit to learn about the study, provide written informed consent, and to assess for inclusion and exclusion criteria. Of note, this study collected information on genotypes encoding endogenous opioid receptors thought to mediate the stimulating effects of alcohol , as well as those associated with metabolism of alcohol . Participants provided a saliva sample for DNA analyses and completed a medical screening that included a physical examination. Detailed information on recruitment procedures are available in the primary manuscripts from which the current study is based . A study procedure flowchart can be seen in Figure 1.Study procedures followed a double-blind, randomized, placebo-controlled and counterbalanced design.Within each medication condition, participants were titrated to the medication for 5 days . Participants completed an fMRI scan on day 4 and an alcohol self-administration session on day 5 of the medication regimen. At the start of each experimental session, participants completed a urine toxicology screening; all participants tested negative for exclusionary substances during these screening periods. There was a minimum wash-out period between medication conditions of 7 days, with a range of 7-10 days. Regarding medication adherence, naltrexone and placebo capsules were packaged with 50mg of riboflavin. A visual inspection of riboflavin content under ultraviolet light indicated that all urine samples tested positive for riboflavin content. At the start of the scanning session , participants were required to have a BrAC of 0.00 g/dL, negative urine toxicology screen for all substances except cannabis, and negative pregnancy screen. Participants who smoked cigarettes were allowed to smoke 30 minutes prior to the scan to prevent acute nicotine withdrawal and craving.Within each task trial, participants initially viewed a visual cue for 2 seconds, followed by a fixation cross . The word “Taste” then appeared, corresponding to oral delivery of the indicated liquid at the start of the trial . Participants were also instructed to press a button on a button box to indicate the point at which the bolus of liquid was swallowed and this information was used to model motion associated with swallowing. There were two runs of this task, with 50 trials per run.Red or white wine, based on participant preference, was used as the alcohol stimulus; previous work from our group has demonstrated that this paradigm has been used to effectively elicit alcohol-related neural activation . Carbonated alcohol, such as beer, could not be systematically administered with the paradigm apparatus and was not offered as a drink option to participants. Visual stimuli and response collection were programmed using MATLAB and Psychtoolbox , and visual stimuli were presented using MRIcompatible goggles. Participants completed an oral alcohol self-administration paradigm on day 5 of medication titration. At the start of this session, participants were required to test negative for substance use and to have a BrAC of 0.00 g/dl. Female participants were also required to test negative on a pregnancy test. Participants fasted for two hours prior to the session and were given a standardized meal before the alcohol administration. Participants initially completed an intravenous alcohol administration discussed in the primary manuscript . After completing the alcohol infusion paradigm and reaching a target BrAC of 0.06 g/dl, the IV was removed and, after a standardized period of five minutes, participants subsequently began an oral self-administration session at the testing center. Notably, the alcohol dose of 0.06 g/dl prior to the self-administration period was higher than the typical 0.03 g/dl priming dose implemented in self-administration tasks During the self-administration period, participants were provided 4 mini-drinks of their preferred alcoholic beverage and allowed to watch a movie over a 1-hour period.

Once respondents had been classified into different groups based on the trajectory analysis, we reviewed the characteristics of the respondents assigned to each trajectory to identify between-trajectory differences . We reviewed the characteristics of members of each trajectory; dichotomous variables are reported as percentages, and ordinal variables are reported with means and confidence intervals. Participants identifying as males were more likely to have established smoking habits at a younger age; while less than half of never smokers, experimenters, and late escalators were male, 59% of quitters and 72% of early established smokers were male. While 31% of never smokers reported ever drinking alcohol at baseline, 39% of late escalators, 48% of experimenters, 59% of quitters, and 66% of early established smokers reported ever drinking alcohol. Similarly, 8% of never smokers reported cannabis use at baseline relative to 25% of late escalators, 20% of experimenters, 33% of quitters, and 42% of early established smokers. For the depression, peer smoking, and rule breaking scales, the differences between never smokers and early established smokers ranged between 0.10 and 1.85 on a 5-point scale. We compared the means and confidence intervals for all variables in the entire NLSY cohort and those in the subset included in the trajectories analysis to assess potential bias in the sample due to missing data. We found that, among the sociodemographic indicators, the subset of observations included in the trajectories analysis had a larger share of respondents identifying as non-Hispanic White and as being both enrolled in school and employed, while a smaller share identified as Hispanic, reported that they were not living with both biological parents and had a mother with less than a GED/high school diploma.Overall, as anticipated, we identified significant associations between smoking trajectories, tobacco control policy interventions and known risk factors for progression to established smoking. Our findings were consistent with and expand on results from prior research by adding the time-varying effects of two important tobacco policy interventions, smoke-free laws and taxes. In addition, our results demonstrate the effects of socio-demographic variables on patterns of smoking. Our results suggest that policy has different influences on the patterns of smoking behavior of different types of smokers. Our analysis also demonstrated the stronger effects of smoke-free laws on frequency of smoking than tobacco taxes.

Our findings with respect to risk factors for smoking frequency were generally consistent with previous research,pot for growing marijuana which suggested that white men were more likely to be daily smokers; smoking is associated with alcohol and drug use, peer smoking, and a history of rule breaking; established smoking is associated with lower socioeconomic status; and depression and anxiety are associated with smoking. A previous trajectory analysis using NLSY97data that did not include time-varying covariates and relied on latent class growth analysis identified roughly comparable shares of experimenters and quitters, smaller shares of never smokers , and larger shares of late escalators and early established smokers. With respect to risk factors, confidence intervals in this updated analysis were narrower, identifying significant associations for additional variables in one or more trajectories, including male, being employed and not in school, ever using cannabis, age, depression/anxiety, peer smoking, rule breaking, and having at least one child. In this analysis, non-Hispanic Black participants were also more likely to be experimenters, and Hispanic participants were less likely to be early established smokers. Our analysis expands upon the existing literature on tobacco control policies and smoking behavior, which focuses on measures of smoking behavior at specific time points, such as initiation, smoking status, and cessation. This is the first analysis to examine the relationship between tobacco control policies and patterns of smoking behavior over time. Our finding that policies have differential effects on smoking trajectories establishes that smokers are heterogeneous, meaning not all smokers follow the same progression to smoking. It may be necessary to tailor cessation interventions to different types of smokers to increase the efficacy of these approaches. The results also support the importance of tobacco control policy interventions in modifying smoking behavior across all trajectories of use. Comprehensive smoke-free laws were associated with decreased risk of initiation, decreased use, and reduced likelihood of return to use across four out of five trajectories. The effects were greatest for never smokers and quitters, while still evident among established smokers, whether they began smoking as adolescents or as young adults. The only trajectory that did not reduce its exposure to tobacco as a result of coverage by comprehensive smoke-free laws was experimenters. Our finding that smoke-free laws were not associated with patterns of use among experimenters is consistent with previous literature that established varying effects of smoke-free laws across different patterns of smoking behavior. Siegel et al found that strong smoke-free restaurant laws were associated with lower odds of transitioning from experimentation to established smoking, but not of transitioning from nonsmoking to experimentation. Song et al found that smoke-free laws had a different relationship with smoking initiation, smoking status, and days smoked.

Specifically, Song et al found that smoke-free bar laws were associated with lower odds of being a current smoker and fewer days of smoking but not lower odds of smoking initiation. Our findings are also consistent with the intention of smoke-free laws not to prevent experimentation, but to prevent progression from experimentation to established smoking, in addition to protecting nonsmokers from secondhand smoke exposure. The knowledge that experimenters are more likely to have counter intuitive responses to smoke-free laws has the potential to influence tobacco cessation efforts. When a state or locality improves its smoke-free law coverage, it may wish to supplement these changes with smoking prevention and cessation targeting experimenters to ensure that no group fails to benefit from these policy improvements. The analysis that this one builds upon revealed that, compared to never smokers, experimenters were more likely to be neither in school nor working. This finding suggests that school-based tobacco control efforts are less likely to be effective for experimenters than some other types of smokers. Tobacco control programs targeting these youth should be tailored to their use patterns by promoting complete cessation and elimination of occasional or social smoking. These efforts should be placed in locations likely to be frequented by youth who are neither in school nor employed, such as community centers and athletic courts. While increased tax rates were associated with reduced risk of initiation among never smokers , reduced days of smoking among experimenters,container for growing weed and reduced likelihood of return to use among quitters, they were associated with increased days of smoking among early established users and late escalators. The finding that established users increase smoking after tax increases is contrary to the intended effect of tobacco tax increases. In general, because cigarettes are addictive, the relationship between changes in the price and consumption of cigarettes tends to be different from that of many other goods. In addition, previous research suggests that, when tax increases occur, smokers increasingly engage in price minimization strategies such as coupons, bulk purchasing, and switching to discount brands to maintain their prior levels of use. In addition, tobacco manufacturer use price promotions to reduce the post-tax consumer prices of cigarettes to levels below the pre-tax prices.

Because these changes result in smokers purchasing cigarettes in larger quantities , they also have the potential to result in increased availability, and therefore, increased use. In addition, the use of price minimization strategies and coverage by tobacco-free policies tend to vary by socioeconomic status, and we found differences in some indicators of SES across classes. Policy interventions such as tobacco minimum floor prices or sudden, large tax increases might circumvent the price-minimization strategies likely to be used by established users and late escalators. Future research could consider the effectiveness of these policies by considering changes in smoking trajectories in years beyond 2011, after the introduction of substantial state level annual tax increases and local tobacco minimum floor prices . In addition, to ensure that all youth benefit from tax increases, states and localities planning tax increases could supplement these increases with cessation methods targeting early established smokers and late escalators. These were the only two trajectories that were significantly more likely to report having frequently broken rules in school compared to never smokers in a previous analysis. School-based efforts and tobacco educational campaigns targeting youth who self-report higher rates of rule-breaking would be most likely to be effective for these types of smokers. In addition, because late escalators do not become established smokers until late adolescence or early adulthood, these programs should extend their reach beyond youth to include young adults by utilizing not only school-based, but also community- and higher education-based smoking prevention and cessation approaches.Our study has limitations. Our analysis considered annual changes and does not consider policy changes after 2011 when NLSY97 data collection became biennial because the analytic method could not support missing years of data. Because we did not analyze NLSY97 data beyond 2011, we were unable to assess potential interactions between combustible cigarette use and new products such as e-cigarettes and possible complementary use of other substances such as cannabis, which has been increasingly legalized for medical and recreational use. Research using data from the CDC National Youth Tobacco Survey showed that the advent of e-cigarettes had not affected the rate of decline in youth cigarette use from 2004 through 2014 , but that e-cigarettes were adding to nicotine product use. The market for new tobacco products has continued to change, and caution is warranted in attempting to apply these findings to the current market. Our analysis did not include data on Tobacco 21 laws due to similar limitations. Although biennial NLSY datasets were available through 2018 at the time of writing, the only strong state T21 law in effect before 2019 was California, and organizations that code the strength of Tobacco 21 laws were unable to supply data on local Tobacco 21 laws for any time period. In addition, the switch to a biennial analysis would increase the share of missing data. Our analysis did not include data on state tobacco control funding, for at least two reasons: first, there are multiple differences between states relating to population and focus and quality of programs that make it unclear how to normalize a measure; second, there is likely collinearity between program funding and enactment of smoke free laws and tax increases, given that stimulating such policy change is often among the goals of state tobacco control programs. We used only a subset of the entire sample due in part to missing geographic identifiers in the underlying data and in part due to incomplete risk factor data ; it is unclear whether or how observations excluded due to missing geocodes or incomplete reporting might affect estimates. We relied on list wise deletion as a strategy to handle missing data given that this method is linked to loss of statistical power rather than to biased estimates. The fact that we identified statistically significant determinants of the trajectories suggests that this loss in power did not compromise the overall analysis. Another consequence of missing data is that we were unable to include a variable indicating ever use of cocaine/hard drugs, which dropped out of the analysis entirely . Another limitation of the analysis is the composition of the sample. A large proportion of the sample was non-Hispanic white and both enrolled in school and employed; a small proportion was Hispanic, not living with both biological parents, and had a mother with less than a GED/high school diploma. As a result, the analysis may not have identified some associations among respondents with underrepresented characteristics. Future research should consider questions left unanswered by this analysis, including further analysis of the identified increase in smoking days among experimenters under comprehensive smoke-free laws, and among early established and late escalators under higher excise taxes.Fragile X syndrome is an X-linked dominant disorder caused by the expansion of a trinucleotide repeat n within the first exon of the fragile X mental retardation 1 gene, which silences the expression of the fragile X mental retardation protein .The absence of FMRP, an important regulator of translation of many messenger RNAs involved in synaptic plasticity,2 leads to substantial intellectual deficits.

They further suggest that attentional bias to threat may mediate the association between CB1 receptor availability in the amygdala and threat symptomatology, with greater CB1 receptor availability being linked to greater attentional bias to threat that is in turn linked to greater severity of threat symptomatology. Results of the current study build on extant neurobiological studies that have implicated the endocannabinoid system in the amygdala as an important modulator of anxiety , as well as functional activation of the amygdala in mediating attentional bias to threat among individuals with PTSD . Specifically, results of this study suggest that CB1 receptor availability in the amygdala may directly mediate this endophenotype and its associated phenotypic expression of trauma-related threat symptomatology. Preclinical work suggests that the activation of membrane glucocorticoid receptors appears to engage a G-protein-mediated cascade through the activation of Gs proteins that, in turn, increases the activity of cAMP and protein kinase A. This increase in protein kinase A appears to induce the rapid synthesis of an endocannabinoid signal through an as yet unknown mechanism that may be an increase in intracellular calcium signaling that is then released from principal neurons in the amygdala and activates CB1 receptors localized on the terminals of GABAergic neurons in the amygdala. It should be noted, however, that other mechanisms than CB1 receptor stimulation by anandamide could contribute to the etiology of attentional bias to threat and threat symptomatology. First, the two endocannabinoids anandamide and 2-arachidonoylglycerol have differential roles in endocannabinoid and have distinctly different metabolic pathways fatty acid amide hydrolase for anandamide and monoacylglycerollipase for 2-arachidonoylglycerol; . To date, the relative contribution of these two endocannabinoids and their pathways in the modulation of anxiety remains unclear. Furthermore, recent evidence suggests that CB1 receptor signaling varies across brain regions , and that diverse effects of anandamide–CB1 receptor signaling mechanisms are evident even within the extended amygdala . Finally, the actions of anandamide are not restricted to CB1 receptors,mobile vertical rack as endocannabinoids also act on CB2 receptors , GPR55 , transient receptor potential vanilloid type 1 channels , and other G-protein subtypes .

Although additional research is needed to further evaluate how the endocannabinoid system mediates attentional bias to threat, the results of this study suggest that greater CB1 receptor availability in the amygdala, as well as lower levels of peripheral anandamide, are associated with a greater attentional bias to threat in trauma-exposed individuals. However, we acknowledge, that no human studies that we are aware of have found that anandamide concentrations directly influence CB1 receptor availability, and hence additional work is needed to ascertain how these variables are causally related. Nevertheless, the present data extend prior work linking attentional bias to threat to hyperarousal symptoms to suggest that the CB1 receptor system in the amygdala is implicated in modulating attentional bias to threat that is in turn linked to the transdiagnostic and dimensional phenotypic expression of trauma-related threat symptomatology. Further research will be useful in further elucidating molecular mechanisms that account for the observed association between CB1 receptor availability and the endophenotypic and phenotypic expression of threat processing in humans. An important question to be addressed in future work is whether pharmacotherapies that act on catabolic enzymes for endocannabinoids may be useful in the prevention and treatment of endophenotypic and phenotypic aspects of trauma-related threat symptomatology. Emerging evidence supports the potential utility of such targets, suggesting that variation in the FAAH gene is linked to reduced expression of FAAH that consequently results in elevations in circulating levels of anadamide , as well as decreased amygdala response to threat and more rapid habituation of the amygdala to repeated threat . Notably, elevating anandamide levels via FAAH inhibition appear to provide a more circumscribed spectrum of behavioral effects than blocking MAGL that could potentially result in a more beneficial side effect profile, as anandamide is less prone to CB1 receptor desensitization and resultant behavioral tolerance . These classes of compounds are currently being investigated for their potential efficacy in treating mood and anxiety disorders. Given that core aspects of threat symptomatology such as hyperarousal are key drivers of more disabling aspects of the trauma-related phenotype such as emotional numbing , pharmacotherapeutic targeting of threat symptomatology in symptomatic trauma survivors may have utility in reducing the chronicity and morbidity of trauma-related psychiatric disorders such as PTSD, MDD, and GAD. Methodological limitations of this study must be noted. First, we studied a cohort of individuals with heterogeneous trauma histories.

Although this is typical for most PTSD studies and we endeavored to recruit individuals who represented a broad and representative spectrum of traumarelated psychopathology, additional studies of samples with noncivilian trauma histories will be useful in extending these results. Second, 95% confidence intervals for coefficients in the mediation analysis were markedly wide, and hence additional studies in larger samples will be useful in ascertaining magnitudes of the observed associations. Third, we observed a high correlation between threat and loss symptomatology that may call into question the extent to which these symptom clusters reflect separable components of trauma-related psychopathology that are uniquely related to CB1 receptor availability in the amygdala and attentional bias to threat. Nevertheless, high correlations among symptom clusters of trauma-related psychopathology are not uncommon, with confirmatory factor analytic studies of substantially larger samples often observing intercorrelations among symptom clusters 40.80 . Furthermore, the finding that CB1 receptor availability in the amygdala was associated only with threat, but not loss symptomatology, suggests greater specificity of association that accords with prior work . Fourth, it is important to recognize that our outcome measure in this study, VT, represents specific plus nondisplaceable binding. Because of the lack of a suitable reference region devoid of CB1, we and others using different CB1 receptor ligands cannot directly calculate binding potential , a measure of specific binding. Thus, an implicit assumption in the interpretation of our results is that there are no group differences in VND, the distribution volume of nondisplaceable tracer uptake. An alternative assumption would be that the magnitude of nondisplaceable binding is small compared with the total binding. To definitively address this issue would require a blocking study in humans to estimate VND. To the best of our knowledge, such data are not currently available because of the lack of suitable selective CB1 antagonist drugs approved for human use. Blocking data with the CB1 receptor antagonist rimonabant in baboons , however, did show a large reduction in tracer uptake, suggesting that a substantial fraction of VT can be attributed to specific binding. Notwithstanding these limitations, the results of this study provide the first known in vivo molecular evidence of how a candidate neuroreceptor system—CB1—relates to attentional bias to threat and the dimensional expression of trauma-related psychopathology. Results revealed that greater CB1 receptor availability in the amygdala is associated with increased attentional bias to threat, as well as the phenotypic expression of threat-related symptomatology, particularly hyperarousal symptoms. Given that these results were based on a relatively small sample, further research in larger, transdiagnostic cohorts with elevated threat symptomatology will be useful in evaluating the generalizability of these results, as well as in examining the efficacy of candidate pharmacotherapies that target the anandamide–CB1 receptor system in mitigating both the endophenotypic and phenotypic expression of threat symptomatology in symptomatic trauma survivors.

SU initiation typically begins in the teens. According to the 2016 Monitoring the Future Survey, 7.3% of 8th graders have used alcohol, 5.4% have used marijuana, and 2.6% have used tobacco within the last 30 days. Marijuana,vertical grow rack alcohol and other substances of abuse are known to negatively impact neuro development in adolescents suggesting that the adolescent brain may have heightened vulnerability to toxic substance effects . The Adolescent Brain Cognitive Development Study is a large-scale, prospective, longitudinal, multi-site project designed to study brain and cognitive development in youth, as they transition into adolescence and young adulthood, across the United States . Participating families are recruited through school and community events at each respective ABCD study site, online and paper ads, and word of mouth. This is the first study of its kind in the US to focus on factors of critical importance to trajectories of developmental change in brain and cognition during a period of vulnerability to substance use and other mental health problems. Study outcomes will inform evidence based standards for normal cognitive and brain development, as well as provide large repositories of data and bio-materials for the study of experiential and environmental influences on brain and cognitive development in youth. Focus on the contributions of pubertal hormones, genomic and epigenomic factors, and the interactions across these many influences, are serving as key biological measures for informing our understanding of developmental and behavioral outcomes in the ABCD study. To this end, along with brain imaging, neurocognitive, and other measures, including a comprehensive battery of mental and physical heath, history of SU, behavioral assessments and key bio-samples are being obtained from participating youth . The present manuscript describes the rationales for inclusion and selection of the specific bio-specimens, methodological considerations for each measure, future plans for assessment of bio-specimens during follow-up visits, and preliminary ABCD data for some example topics. All procedures are approved by each site’s Institutional Review Board, and all participants undergo verbal and written consent/assent procedure.A description of the rationales for inclusion and selection of the specific bio-specimens, methodological considerations for each measure, future plans for assessment of bio-specimens during follow-up visits, and preliminary ABCD data to illustrate methodological considerations for all biological samples under collection from youth. These include breath, saliva, urine, hair, blood and baby teeth, collected for purposes of: screening for SU; measurement of pubertal hormone levels; characterization of genetic and epigenetic factors, and analyses of environmental exposures during development from baby teeth. Bio-material obtained from the ABCD Study are being stored in repositories, such as the Rutgers University Cell and DNA Repository , and baby teeth at the Icahn School of Medicine at Mount Sinai in the laboratory of Dr. Manish Arora. These stored bio-materials include measures from the assay of bio-specimens, genotyping, and bio-samples collected for future research. Preparation and processing of bio-samples at the ABCD data collection sites is occurring during or just following baseline assessment of youth, and is planned for follow-up assessments for utilization by members of the scientific community. Results from analyses of all ABCD bio-specimens will be made available through the ABCD Data Repository. Although we anticipate core specimens to be the same across the ten years of ABCD, the kinds and/or amounts of specimens to be collected in subsequent follow-up years may be adjusted to account for: 1. changes in technology; 2. shifts in the scientific questions being addressed ; or additional funding for analyses. Given these considerations, future specimen collections may include measures of the microbiome, parental specimens, or other types of specimens in subsequent follow-up years.The ABCD study baseline visits occur at 9–10 years of age, prior to initiation of SU for most youth allowing for measures of brain, cognitive, environmental, and genetic variability that may precede SU or other negative developmental influences. The ABCD study uses a combination of bio-specimens and self-report to evaluate consistency between biological testing, participant self-report and research assistant assessment of intoxication. Self-report alone may lead to biases due to under-reporting related to individualized motivations, or errors in recall . Further, as seen with youth self-reporting risky sexual behaviors, inaccurate self-reporting may vary as a function of race, gender or age . However, bio-specimen sampling itself is subject to experimental error, and therefore reporting bio-specimen measures in a thorough and standardized manner across published ABCD studies is important for accurate and reproducible results . Self- and parent/guardian-report of SU is conducted through interview and questionnaire survey. Bio-specimens include the annual collection of hair samples to evaluate recent and repeated use of alcohol and other drugs during the 1–3 months prior to testing, and testing of body fluids and breath prior to onsite assessment. Because of the low levels of SU among 9–10 year olds, only a small subset of youth participants are tested in the  first two years of the ABCD Study, with increasingly larger proportions of youth selected randomly for testing as the cohort ages into adolescence, when experimentation, regular, and problem use with substances becomes more prevalent .

The first column of Fig. 3 illustrates this data type using the Area Deprivation Index, a measurement of neighborhood deprivation derived from the American Community Survey. The second column in Fig. 3 illustrates traffic counts, which are point data that were obtained by surveying stations at various geographical locations. In contrast, raster data are usually obtained by model estimation, incorporating multiple sources such as satellite imaging and ground station surveys, as is seen for fine particulate matter in the third column of Fig. 3. The curated GIS database compiled by the ABCD Study LED Environment Working Group includes both vector and raster data of multiple built and natural environmental contextual variables. As shown in Table 1 and outlined in greater detail below, various environmental datasets have been used to map environmental factors to the state-, census-, residential-level for ABCD Study participants to date. Youth grow up in overlapping circles of cultural and socio-political contexts, from their local family and neighborhoods to the states and countries in which they live. We typically focus on the experience of stigma and bias at a relatively local level . Critically, there are also important indicators of more systemic or structural bias reflected in social norms at the community or institutionalized laws, policies and practices that may either reflect the behavior of individuals or shape the behavior of individuals in youths’ local environment. However, we rarely directly examine the relationship between objective measures of systemic/structural bias and function in youth. The ABCD Study provides a novel opportunity to address such critical questions with empirical data, given the geographic variability of the sites involved in the ABCD Study, which affords significant divergence across youth in their exposure to such systemic biases. To address such questions, colleagues at Harvard University created state-level indicators of three types of structural stigma : gender , race , and ethnicity . This information was linked to each youth in the ABCD Study as a function of their baseline site of participation and does not yet include information about whether the child moved to a different state, which may have different state level indicators, at later visits. To create these state-level measures, they used several types of data described in detail in . First, they obtained data about implicit and explicit attitudes about each of these three identity groups aggregated at the state-level, derived from large-scale projects that spanned several years: Project Implicit , the General Social Survey , and the American National Election Survey . Second, for information on gender, they obtained state-level data of women’s economic and political statuses and information about reproductive policies, such as information about availability of abortion providers. Third, for information on attitudes towards Latinx individuals, they examined state-level policies on immigration, recognizing that many Latinx individuals are not immigrants but that such state-level policies likely influence the experience of all individuals in the community with that identity.

These data can be used to examine how these state level biases interact with youth’s identities to predict a range of factors,mobile vertical rack such as educational experience, mental health, brain development, and substance use/abuse. In the United States, public acceptance of cannabis use has increased alongside increased access because of broader cannabis legalization. Currently, 36 states have legalized either recreational or medical cannabis use.However, among younger adolescents , greater exposure to cannabis advertisements was associated with greater use, intention to use, and positive expectancies . The difference in results as a function of age highlights the importance of understanding how cannabis regulations affect younger cohorts of children and adolescents who may have greater exposure to cannabis advertisement after living in an environment with legal access to cannabis for a longer period. Furthermore, the ABCD Study is an ideal dataset to examine the effects of cannabis legalization because there are 21 sites located in 17 states with various state cannabis policies. In addition, the ABCD Study is collecting detailed substance use data unlike other national surveys. Cannabis legalization categories were assigned to participants based on their state of residence. The four cannabis legalization categories are: 1. Recreational – allows adults to use cannabis for recreational purposes, 2. Medical – allows adults to use cannabis for medical conditions, 3. Low THC/CBD – allows adults to use cannabis that is low in THC and high in CBD for medical conditions, and 4. No legal access to cannabis – forbids access to cannabis. Urbanicity can provide information as to the impact of living in urban areas. Urbanicity indices may reflect the presence of environmental and social conditions that are more common in urban areas, such as pollution, congestion, and increased rates of social interactions. To date, various health factors have been linked to urbanicity, such as increases in overweight/obesity, increased calorie intake, decreased physical activity, increased drug and alcohol use, and mental health disorders, among many others . In the ABCD Study, we have linked five measures of urbanicity to residential addresses, including two density measures , census-tract derived metrics classifying the locations as urban or non-urban areas, walk ability, and motor vehicle information including distance to roadway and traffic volumes. Population density refers to the number of people living in a given unit of area . Differences in population density have been linked to psychological and environmental quality of life , and has been shown to moderate relationships between the built environment and health outcomes .

Thus, information about variability of population density may be important for contextualizing relationships between the build environment and health outcomes in the ABCD Study. As such, the population density from the Gridded Population of the World , provided by the Socioeconomic Data and Applications Center , has been linked to ABCD individual participant address information. National-level population estimates from 2010 used in this metric have been adjusted to the United Nations World Population estimates, which can often be corrected for over- or under-reporting and mapped to an ~1-km grid. Population density values represent persons per km2 . Similarly, gross residential density is a measure of housing units per acre on unprotected land and is an alternative measure of crowding. This measure was obtained from the Smart Location Database created by the United States Environmental Protection Agency based on the 2010 Census Data and also linked to ABCD Study individual addresses. While many studies have documented the effects of increased urbanicity on child and adolescent health outcomes, few studies have focused on differential risk associated with living in a rural area relative to an urban area . Although the number of studies devoted to this topic are few, linking this information to the ABCD Study may provide an opportunity to further investigate both positive and negative impacts of living in an rural area. To classify individuals as living in a rural or urban area, urban-rural census tract variables from 2010 were mapped to each address. Based on this external database, the Census Bureau identifies two types of urban areas, including Urbanized Areas of 50,000 or more people and Urban Clusters of at least 2500, but less than 50,000 people. Rural areas are those that encompass all population, housing, and territory not included within an urban area . In urban places, city planning designs have limited the walk ability between work, home, and recreational spaces, with distances too great to walk . Such reduction in walk ability leads to fewer opportunities for physical activity and a risk for health. Understanding potential links between the walk ability of the built environment of the child and physical and mental health outcomes is important in the context of the ABCD Study . A measure of walk ability was linked to ABCD participant addresses using the National Walk ability Index from the Smart Location Database created by the United States Environmental Protection Agency based on 2010 census data. Walk ability scores were calculated at the census-tract level,vertical grow rack ranking each census tract on a range from 1 to 20 according to relative walk ability. The walk ability score is based on a weighted formula that uses ranked indicators as related to the propensity of walk trips.

The ranked-indicator scores used in the weighted formula include a combination of diversity of employment types plus the number of occupied housing, pedestrian-oriented intersections, and proportion of workers who carpool. Beyond population density and walk ability, epidemiological studies have also reported associations between road proximity and brain health. Various neuro development, cognitive functioning, and mental health outcomes have been linked to living near major roadways . As such, the ABCD Study may be valuable to help understand how the distance of a child’s home to major roadways as well as the daily traffic patterns on nearby roadways impacts cognitive and neuro developmental trajectories over time. Therefore, we have mapped road proximity and traffic volume estimates to residential addresses of the child in the ABCD Study to provide insight into both the major roadways nearby and how many cars and trucks typically utilize these roads. the geospatial coordinates of the major roads were obtained through the North American Atlas for roads, as last updated July 2012 , and the shortest distance to a major roadway in meters was linked to participant’s residential addresses. In the field of developmental cognitive neuroscience, socioeconomic status has traditionally been treated as an individual-level variable, specific to each family or person. However, socioeconomic status can also be attributed to neighborhoods and communities, which may represent an independent construct from family-level socioeconomic status with considerable effects on child development . In the ABCD Study, detailed questions are asked about socioeconomic and social factors at the family-level. Thus, the ABCD Study is an ideal dataset to examine the independent and multiplicative associations of family- and neighborhood-level socioeconomic status on adolescent health. Investigations with these ABCD data can elucidate the underlying mechanisms by which various contexts uniquely influence development and potential emerging health disparities . Accordingly, the ABCD Study has incorporated the Area Deprivation Index measure of neighborhood-level socioeconomic status in past data releases, as well as information on crime and risk of lead exposure. Moving forward, three additional metrics, including the Social Vulnerability Index, Opportunity Atlas, and the Child Opportunity Index, have been linked in the 4.0 annual data release. The neighborhoods in which children in America grow up can influence outcomes in adulthood. As such, the Opportunity Atlas estimates measures of average outcomes across 20,000 people in adulthood according to the census tracts in which they grew up . The ABCD Study includes scores from the Opportunity Atlas that indicate the predicted 2014–2015 mean income earnings of adults aged 31–37 years that grew up in that census tract as children. Scores are provided based on the childhood census tracts of the Opportunity Atlas cohort, but we also provide the adult mean earnings disaggregated by parental household income percentiles based on the national income distribution during their childhood. For example, the mean income earnings at the 25th percentile rank correspond to the mean income earnings of adults whose parents were at the 25th percentile of the national income distribution.Although the outcomes for census tracts are based on children who were born in those tracts between 1978 and 1983, Chetty et al. suggest that these longitudinal outcomes are best suited for measuring stable outcomes in earnings in adulthood. Linking measures from the Opportunity Atlas to the ABCD Study allows for objective measures of neighborhood economic opportunity to study in relation to health outcomes in ABCD youth. However, while the Opportunity Atlas estimates can be used as predictors of economic opportunity for children today, it is important to combine these estimates with additional data to determine applicability to neighborhoods that have undergone substantial change in the last several decades. There are vast differences in neighborhood access to opportunities and quality of conditions for children across America, including access to good schools and healthy foods, green spaces such as safe parks and playgrounds, safe housing and cleaner air. These inequitable neighborhood differences can negatively influence the current living conditions of a child, as well as development throughout childhood and subsequent health outcomes in adulthood . Children who grow up in neighborhoods with access to more educational and health opportunities are more likely to grow up to be healthy adults.

Significant sex differences in these domain summary scores were followed by analyses of covariance adjusting for covariates and biopsychosocial factors. Lastly, among HIV-positive and HIV-negative participants, we examined the moderating role of sex in the relationship between HIV serostatus and the likelihood of NCI in two logistic regression approaches: inclusion of an HIV-serostatus by sex interaction term and examination of the HIV and NCI relationship in sex-stratified analyses. Significant effects were followed by stepwise logistic regressions adjusting for covariates and individual biopsychosocial factors . Significance was set at P value less than 0.05. Analyses were performed using SPSS . Given race/ethnicity differences in the prevalence of biopsychosocial factors and NCI, analyses were repeated within nonhispanic whites and blacks.Our findings present evidence supporting greater NCI among HIV-positive women than HIV-positive men. Race/ethnicity-stratified analyses indicated that this sex difference was primarily due to a higher proportion of black women in the HIV-positive, versus HIV-negative, group. We extend previous findings by determining whether discrepancies in biopsychosocial factors may explain higher rates of HIV-associated NCI in women. In partial support of hypotheses, adjusting for low reading level eliminated the sex difference in HIV-associated NCI. The race disparity in findings may be due to the overall higher rates and larger sex difference in biopsychosocial factors in blacks versus whites. The race disparity may also be partially due to race/ethnicity differences in health literacy, which have accounted for racial disparities in age-associated cognitive decline. Perhaps sex differences in HIV-associated NCI are more common in the context of low health literacy possibly due to sub-optimal engagement in HIV care/treatment. Alternatively, reading level may represent other NCI risk factors that show a female preponderance among black, HIV-positive individuals but were unmeasured.

Our race/ethnicity differences may explain inconsistent findings. Because our sample included more black women with lower reading level,grow cannabis the sex differences in HIV-related NCI may be more evident than in predominantly white samples. Low reading level was the only biopsychosocial factor to attenuate the sex difference in HIV-associated NCI in the overall sample and blacks. This may be because, among the biopsychosocial factors, low reading level demonstrated the strongest relationship with NCI and the largest sex difference. Low education was not associated with NCI likely because NCI was determined using education-adjusted, neurocognitive T-scores. SUDs were not associated with NCI possibly because most SUDs in our sample were not current . Furthermore, reading level may better reflect education quality than years of education, especially in lower socioeconomic populations because of the many factors impacting education quality. Notably, low reading level, but not education, was a risk factor for cognitive decline among ethnically diverse elders in the general population. In addition, reading level is associated with health outcomes, including hospitalizations and outpatient doctor visits, and, thus, may be a proxy for biopsychosocial factors underlying general health . Although mean syndemic count was higher in HIV positive women versus HIV-positive men, adjustment for syndemic count did not attenuate the sex difference in HIV-associated NCI, suggesting that the other biopsychosocial factors dilute the sex-related variance explained by reading level.Given findings that stress is more strongly associated with trajectories of cognitive impairment than depression in HIV-positive women, a syndemic count that included factors such as early life trauma and perceived stress may better capture biopsychosocial differences between HIV-positive men and women. Sex differences in the profile of HIV-associated NCI were only observed within race/ethnicity groups. Among whites, women demonstrated poorer learning than men, and this difference was attenuated after adjusting for reading level. White women also demonstrated poorer verbal fluency than white men and this difference was unchanged after adjustments. The sex difference in HIV associated NCI among blacks was not driven by specific cognitive domains. In fact, in contrast to whites, black women outperformed black men in verbal fluency and this difference was unchanged after adjustments. Sex differences in verbal fluency were likely masked in the overall sample due to differing associations within race/ ethnicity groups.

The sex by HIV interaction was not significant; however, sex-stratified analyses suggest a moderating role of sex in the HIV and NCI association, particularly in blacks. Compared with their HIV- counterparts, NCI was 3.5 times more likely in black, HIV-positive men but six times more likely in black, HIV-positive women. Adjustment for reading level marginally attenuated the HIV and NCI association in black women, suggesting that the large discrepancy in reading level between HIV positive and HIV-negative black women contributes to the higher risk of NCI in HIV-positive black women. Conversely, the HIV and NCI association was unchanged with adjustments in black men. Previously reported sex differences in disease characteristics unmeasured herein may contribute to sex differences in HIV and NCI associations. Overall, results suggest that HIV-positive black women are at the highest risk for NCI. Our study has limitations including the small proportion of women and, thereby, the potential of being under powered to detect an HIV by sex interaction. We were also unable to explore certain biopsychosocial factors . Study strengths include the large sample, an HIV-control group, race/ethnicity-stratified analyses and a comprehensive test battery that defined NCI. Demographically adjusted T-scores based on HIV- data allowed us to examine sex differences in HIV-specific cognitive profiles; however, by restricting this analysis to HIV-positive individuals with NCI, our statistical power was limited. In conclusion, we contribute evidence that HIV associated NCI is more prevalent in women versus men and indicate that this difference is accounted for by a lower reading level among HIV-positive women. The frequent sub-optimal educational experience of HIV positive women and the resulting lower cognitive reserve may make HIV-positive women more susceptible to HIV-associated NCI. The effect of HIV on NCI was also greater in women versus men, particularly among blacks. Adjusting for education quality rather than years of education may improve the specificity of neuropsychological tests for measuring cerebral dysfunction and sex differences in HIV. Clinically, practitioners should be advised that black HIV-positive women appear to be particularly at risk for NCI and provide resources to accommodate for these possible impairments.Alcohol and SUDs in general are associated with dysfunction, primarily in the domains of learning/memory, working memory, and other executive-based skills, including cognitive/inhibitory control . Persons with alcohol use disorder have been studied most, with the nature and level of impairment showing considerable variability. Approximately 55% of AUD manifest clinically significant neurocognitive deficits after acute detoxification , but some degree of recovery from these deficits is apparent with short-term , intermediate-term , and long-term abstinence from alcohol .

Some dysfunction has been reported to persist into long-term abstinence from alcohol, particularly in the domains of executive and visuospatial skills, learning and memory, and postural stability . The degree of cognitive dysfunction and the rate of recovery during abstinence appear to be influenced by many factors such as age, sex, family history of AUD, treatment history, pretreatment alcohol consumption level, number of detoxifications, nutritional status, comorbidpsychiatric and biomedical conditions, and comorbid SUD . Most treatment-seeking substance users today concurrently and/or simultaneously consume more than one illicit/licit compound, so-called poly substance users . Among PSU, comorbid tobacco use disorder is most prevalent in AUD , and chronic cigarette smoking itself is associated with significant neurocognitive deficiencies in both AUD and non-AUD cohorts . Smoking AUD performed worse than their nonsmoking counterparts on domains of auditory verbal learning and memory, processing speed, cognitive efficiency, and working memory during the first month of abstinence from alcohol . Smoking AUD also demonstrated poorer neurocognition with increasing age than never-smoking AUD, and the performance of former-smoking AUD on several domains was intermediate to that of never-smoking and actively smoking AUD . Particularly common among PSU is the simultaneous and/or concurrent abuse of alcohol, tobacco, and psychostimulants . Therefore, in many published research reports on the neurobiological and neurocognitive consequences of AUD, many individuals were also likely nicotine-dependent, and in studies of cocaine use disorder, participants were also likely heavy drinkers. This was both likely and most apparent in literature before about 2010, when poly substance abuse had not been attended to more widely in substance abuse research, and other substance use was largely treated as a nuisance variable. More recently,indoor cannabis grow system poorer health outcomes and greater treatment resistance have been reported for PSU compared to monosubstance users . Despite its prevalence, however, few studies have directly examined the neuropsychological or neurobiological consequences of poly substance abuse. In early studies, cocaine-dependent individuals with and without AUD showed cognitive deficits at 3 months of abstinence , and decision-making was still impaired in similar individuals abstinent for 8 months . Even after several years of abstinence, psycho stimulant-related deficits of episodic memory, planning, and cognitive flexibility were persistent in PSU . These relatively persistent cognitive deficits were associated with the amount of cocaine and cannabis consumed as well as with relapse risk .

Cognitive efficiency, processing speed, and visuospatial learning were less impaired in 1-month-abstinent PSU who continued to abstain versus those who subsequently relapsed between 1 and 4 months of abstinence ; similarly, 1-month-abstinent AUD with the lowest processing speed showed a significantly increased risk for relapse following treatment . In comparisons to 1-month-abstinent AUD, 1-month-abstinent PSU performed worse on measures of auditory verbal memory and learning and general intelligence , suggesting a diminished capacity of learning, memorizing, and integrating new skills presented in clinical treatment settings. In addition, PSU exhibited worse decision-making and higher self-reported impulsivity than AUD, potentially placing them at a greater relapse risk during early recovery. Finally, PSU between the ages of 25 and 70 years showed greater age-related declines in processing speed, general intelligence, cognitive efficiency, and global intelligence than controls, indicating the detrimental cumulative effects of poly substance use on neurocognition . As described, the degree and nature of neurocognitive deficits varies considerably among substance-using groups investigated, critically related to the combination of both illicit and licit substances abused and their use histories. However, it is noteworthy that even mild neurocognitive deficits can impact quality of life and relapse risk . Impaired neurocognition and inhibition may adversely affect maintenance of abstinence during treatment and long-term treatment efficacy ; specifically, neurocognitive deficits can interfere with treatment efficacy by reducing the individual’s ability to encode, process, recall, integrate, and apply program information during and following treatment . As such, assessment of cognitive abilities during treatment may improve treatment outcomes by providing clinicians an understanding of the individual’s capabilities during treatment and inform appropriate post treatment follow-up care . Studies of longitudinal neurocognitive changes during abstinence from alcohol and other substances are far less common than cross-sectional studies . Most longitudinal studies assessed neurocognition several weeks after detoxification and then 6–12 months later; they demonstrated several neurocognitive functions improve at least partially during sustained abstinence, whereas some cognitive dysfunction persists for years after detoxification . Psychological changes in AUD during a residential rehabilitation program have recently been documented and include significant decreases in anxiety, depression, and psychological distress within about 1 month of detoxification in those with substance-induced mood disorders . In studies on the effects of comorbid tobacco use on neurocognitive recovery in AUD , we found that smoking was associated with significantly diminished improvement of visuospatial learning and processing speed within the first year of abstinence from alcohol . We analyzed neurocognition across three different time points during abstinence from alcohol and as a function of smoking status . Over 8 months of abstinence, AUD as a group showed significant improvements of visuospatial learning and memory, processing speed, and working memory, with less pronounced changes in executive functions, postural stability, and auditory verbal learning and memory. Overall, the recovery rates were nonlinear over time, showing faster recovery between 1 and 4 weeks than between 1 and 8 months of abstinence. Improvements in the foregoing domains in AUD were driven by never-smoking AUD, where both former-smoking and actively smoking AUD showed significantly less recovery than never-smoking AUD. Additionally, active smokers showed significantly less improvement with increasing age than never-smoking AUD over 8 months on measures of processing speed and learning and memory. At 8 months of abstinence, currently smoking AUD remained inferior to controls and never-smoking AUD on multiple measures, former smokers performed worse than never-smoking AUD on several tests, but never-smoking AUD were not significantly different from controls on any measure.

We calculated change in both absolute and relative differences across race/ethnicity, because relative differences can increase, even as absolute differences narrow. Relative differences depend on the rate in the reference group ; as rates in the reference group decline, a shrinking absolute difference may correspond to a widening relative difference. To calculate the difference in expected vs. observed counts, we subtracted model-predicted counts from actual arrests during the corresponding period. Confidence intervals were obtained by bootstrapping using 1,000 replications. All analyses were conducted using Stata Version 15.Felony drug arrest rates dropped immediately and precipitously for all racial/ethnic groups during the first month, and continued to decrease over time . In the year prior to Prop 47, the proportion of drug arrests that were felonies was highest for Blacks , suggesting that Blacks would have the most to gain from reclassification of drug felonies to misdemeanors. However, Prop 47 did not reclassify all felony drug offenses, only drug possession. In the year before Prop 47 was passed, the proportion of felony drug arrests for offenses that would be reclassified was 73% among Blacks, vs. 86% among Whites and 83% among Latinos. Thus, relative to Whites and Latinos, we would expect a smaller percentage decline in felony drug arrests of Blacks resulting from Prop 47. Consistent with these predictions, the models adjusted for secular and seasonal trends showed a significant, immediate decline in monthly felony drug arrest rates of 81 per 100,000 among Blacks, compared to declines of 44 among both Whites and Latinos . As a result, the absolute disparity in Black-White felony arrest rates declined by 37 per 100,000 in the first month, from a difference of 81 per 100,000 in the month pre-passage ,vertical grow systems for sale and continued to decrease over time. Felony drug arrest rates among Whites and Latinos were nearly equivalent in the month pre-passage and no difference was evident by one year post-passage.

Though Blacks had the largest decline in absolute felony drug arrest rates, they had the least proportional decline, likely because they had lower proportions of felony drug offenses that were reclassified to misdemeanors by Prop 47. In the first month, felony drug arrests among Blacks declined by 60% , compared to 69% among Whites and Latinos . With a larger percentage decline among Whites, the relative Black-White disparity increased by 27% . Though proportional declines in felonies continued to grow over time for all racial/ethnic groups, differences in declines across groups grew as well. By one year post-passage, felony rates among Blacks were 3.09 times higher than those of Whites , compared to 2.16 times higher in the month pre-policy . The difference in the number of felony arrests made, compared to the number expected based on secular and seasonal trends, was substantial. During the first year of adoption, Prop 47 led to an estimated 51,985 fewer felony arrests among Whites, 15,028 fewer among Blacks, and 50,113 fewer among Latinos . These represent reductions of 75.9%, 66.1%, and 73.7%, respectively. Our analysis of 60 months of county, race, and offense-specific arrest rates in California point to several notable effects of Prop 47. There was little indication of elevated drug arrest rates in Latinos compared to Whites before or after Prop 47, while the large absolute Black-White difference in felony drug arrest rates was reduced. With a higher proportion of felony drug offenses affected by Prop 47 , Whites had the greatest proportional decline in drug felonies, contributing to an increase in the relative Black-White disparity. Prop 47 appears to have led to reductions in arrests for drug offenses overall , which saw a decrease in the absolute Black-White difference, while relative disparities remained the same. There has been little study of the impacts of reducing offense severity on racial disparities in criminal justice involvement. In one exception, researchers found that reforming marijuana laws reduced arrests across all racial/ethnic groups, with no change in relative disparities between Blacks and other racial/ethnic groups . This aligns with our finding on Prop 47’s effect on total drug arrests, though we find increases in relative disparities for felonies.

Why did reducing the classification of some drug offenses reduce drug arrests overall? Reductions in drug arrests were unlikely a reflection of underlying crime trends – violent and property crime rates increased during this period . Prop 47 was a ballot initiative and law enforcement may be responding to perceptions of public opinion about public safety priorities. In areas with high rates of violent crime, police agencies may welcome a freeing up of resources to focus on these offenses. Officers may use their discretion to opt out of drug arrests and focus on offenses their department prioritizes. The initial drop in total drug arrests followed by the rise in month three suggests officers may also be responding to feedback from the courts regarding how to interpret and act on the legislative change. Reductions in arrests for all drug offenses may also reflect fluid lines between drug possession and sale. One lieutenant explained to the first author that in his city, sellers typically plead out to possession up to the third arrest, while arrests for possession were used to get information on sellers . Reducing possession to a misdemeanor may have diminished tools police and prosecutors used to enforce drug laws, contributing to a de-emphasis on arrests. These impacts warrant further investigation. While the absolute Black-White disparity in felony drug arrests decreased, the relative disparity increased, in part because of differences in pre-existing felony offense composition by race/ethnicity. Blacks had larger proportions of felony drug offenses unaffected by Prop 47 did not alter, such as sale. Whether this reflects racial differences in offending, or racial biases and practices in drug law enforcement, cannot be determined from our data, but other studies point to the latter . Prop 47 targeted drug possession, with the aim of decriminalizing substance use disorder. However, distinctions between sale and possession can be murky and influenced by prosecutorial discretion concerning which charges to file. Further study of racial inequalities in drug charges could help to address this unintended effect in California and states considering similar policies. Given substantial evidence of the role of social and economic factors in health outcomes , reducing incarceration and felony convictions through policy reform may be a critical component to addressing racial disparities in health. Our findings suggest that reclassifying drug offenses to misdemeanors is an effective approach to decreasing felony arrests across racial/ethnic groups, and absolute differences between Blacks and Whites.

However, a full assessment of how reducing criminal penalties affected racial/ethnic disparities in criminal justice involvement must go beyond the stage of arrest, particularly since groups may differ in the prevalence of prior convictions, which affect the likelihood of prosecution. Still, there is clear evidence that on a population level, there were declines in incarceration resulting from Prop 47,vertical grow system providing an opportunity to evaluate how reducing exposure affects health and associated racial/ethnic disparities, including the health of families and communities most affected by high rates of incarceration. Regarding more direct health impacts, a core component of Prop 47 was to reinvest savings from reduced incarceration to buttress substance use disorder and mental health treatment, with grants totaling $103 million awarded to 23 city and county agencies in mid-2017 . Prop 47 generated debate about whether arrestees would lose the incentive to enroll in treatment without a felony threat, which remains to be evaluated . Alternatively, populations accessing treatment or the proportions entering through voluntary vs. court-referred admissions may change . Racial disparities in substance treatment access could be impacted by Prop 47 as well. Blacks and Latinos arrested for drug offenses are more likely than Whites to receive incarceration, rather than drug treatment diversion . Sentence standardization initiated by Prop 36 in 2001 reduced disparities, but had a greater impact on Latinos than Blacks, perhaps because Blacks had more prior drug and violent offenses that precluded eligibility for diversion. Treatment resources generated by Prop 47 may have more promise for reducing disparities, given broader participant eligibility criteria stipulated in grant requirements . Critical questions remain regarding how shifting funds from a criminal justice to a public health approach to substance use disorders will influence treatment enrollment and outcomes for health, well-being, productivity, and public safety.

New programs funded by Prop 47 offer opportunities to evaluate these questions, and identify the most effective models for improving public health. In arrests with multiple offenses, only the most severe is included in the dataset. Since Prop 47 reduced the severity of drug possession offenses, one concern is whether some reduction in arrests could be attributed to co-occurring offenses that became comparatively more severe than drug possession postProp 47. This could occur only in measures incorporating offenses classified as felonies pre-Prop 47 and misdemeanors post-Prop 47. These would include drug arrests reclassified by Prop 47 and total drug arrests, but would exclude felony drug arrests, misdemeanor drug arrests, and felony drug arrests unaffected by Prop 47. We used data on juvenile arrests, which contain up to five co-occurring offenses, to estimate possible bias. We found that potential masking was minimal and would not alter findings. Approximately five percent of “drug arrests reclassified by Prop 47” may have been masked post-policy – far less than the 46-51% declines in this category 12 months post-policy. Masking in the “total drug arrests” measure was estimated at three percent, compared to declines of 17-22% at 12-months post policy. Data are also event-, rather than person-level. Some arrests may represent the same person, though we minimized this possibility by using monthly rates. We assessed the extent of possible bias by linking individuals on name, date of birth, and jurisdiction for July 2013; just 1.2% were arrested more than once and 0.1% more than twice. We also lacked data on prior convictions; Prop 47 offenses retain felony classification for individuals with serious and/or violent convictions such as homicide and sexually violent offenses, or convictions requiring registration as a sex offender. The history of more frequent arrests and severe charges among Blacks arrested for drug offenses , may have minimized the effects of Prop 47 on reducing Black-White disparities in felony convictions. Given that other states are pursuing similar policy changes to reduce racial disparities , this effect should be further explored, and limiting prior record exclusion criterion considered. Race/ethnicity in arrests data may be based on officers’ observations, rather than self-report, in population denominators. This could lead to misclassification of the numerator in arrest rates, though sensitivity analyses indicated findings were robust. We also only analyzed three racial/ethnic groups; though these groups make up 95% of arrests in California, further research could assess disparities and impacts among other populations.State-level criminal justice reforms often leave a great deal of room for interpretation and discretion. There can be a tension between the goals of state legislators enacting criminal justice laws and county level officials who administer them, leading to highly county-specific implementation . As an example, mandatory minimum sentencing laws were seen as tough on crime and therefore historically supported by state legislators as a symbolic statement. They were opposed by courts, however, because they increased trial rates and case processing times, and penalties were considered disproportionately severe . In his review of two centuries of mandatory minimum sentencing laws, Tonry found a long history of courts using devices to circumvent them: prosecutors refused to file charges, plea bargaining was used to reduce charges, and judges refused to convict or ignored the statute and imposed a different sentence . When severe mandatory minimums for drug sale were in place in Michigan, for example, nearly every charge was reduced to possession , while harsh minimums for felony possession during the Rockefeller drug law era in New York were circumvented by reducing charges to misdemeanors or referring defendants to drug courts . Scholars have proposed that differences in local contexts determine how discretionary options are used within locales, producing geographic variation in case dispositions. Specifically, cases are prosecuted in accordance with personal and local principles of proportionality , local political leanings, resources for prosecution, and community priorities .

In practice, GMO labeling has not given EU consumers greater choice, because food processors in Europe have recombined ingredients away from GMOs to avoid labeling. As suggested by comments from meat packers, the same pattern may develop with COOL. Just as intended, COOL is a non-tariff barrier to trade; this does not necessarily mean that it will be challenged at the WTO, but it could be vulnerable to such a challenge, or subject to negotiation. At the WTO, country-of-origin labeling is covered as a technical regulation subject to the WTO Agreement on Technical Barriers to Trade which states that countries are allowed to take measures to protect human health or prevent deception of consumers, subject to the requirement that countries are not unjustifiably discriminated against, and that measures do not constitute a disguised restriction on trade.In NAFTA, country of origin labeling is allowed, but requirements must be minimally difficult and costly. Concerns about meeting this requirement may have been what initially prompted Secretary of Agriculture Ann Venneman to speak positively about the suggestion that a “North American” label could be appropriate . COOL compliance may be most costly for developing country suppliers to the U.S. market who lack record keeping infrastructure to maintain audit trails. To this extent, COOL directly conflicts with the spirit of trade liberalization in the Doha Development Agenda, which aims to give preference to the trade agendas of developing countries. To justify the continued existence of the Export Enhancement Program, which purports to offset subsidies and other trade-distorting practices used by other countries, Congress expanded its list of unfair trade practices to include “unjustified trade restrictions or commercial requirements, such as labeling, that affect new technologies, including biotechnology” .

The irony of this new requirement in the same bill mandating country-of-origin labeling will not be lost on U.S. trading partners where consumer distrust of biotechnology, whatever its scientific merits,vertical grow system is an important phenomenon. Challenging labeling of GMOs at the WTO may be more difficult after the passage and implementation of the 2002 COOL regulation.The 2002 Farm Bill roughly doubles annual federal expenditure on environmental programs, including the Environmental Quality Incentive Program , the Conservation Reserve Program and the new Conservation Security Program , from $2 billion to $4 billion, over 1996 levels.Each of these programs benefits producers in California.EQIP provides technical assistance, cost sharing, and incentive payments for producers that undertake qualifying practices that provide environmental benefits. The new CSP provides incentive payments of about $300 million per year for the maintenance or implementation of soil, water, and air quality conservation activities. By paying producers to maintain practices they have previously found to be profitable to undertake, CSP payments are not necessarily intended to internalize environmental externalities but are certainly intended to support agricultural incomes. The continued exemption of environmental payments from support ceilings makes payments for environmental benefits an attractive program for policy makers wishing to subsidize agriculture while meeting WTO obligations. International trading rules have only recently become potential constraints on the form and content of U.S. domestic support to agriculture. The Uruguay Round Agreement on Agriculture introduced a major reform that the U.S. must take into account when setting domestic agriculture policy: a ceiling on so-called trade distorting domestic support for agriculture.

All support for agriculture must be classified as trade distorting, minimally trade distorting, or non-trade distorting, and, while total support levels are unconstrained, trade-distorting support must fall at or below a negotiated cap that declines over time. “Amber box” support is trade-distorting and counts towards countries’ negotiated cap, and “green box” support is deemed not trade-distorting and may be allowed without limits.14 Since supposedly non-distorting “green box” spending is not subject to a cap on support expenditure, identifying support measures that can qualify as “green box” is valuable from the perspective of policymakers wishing to both subsidize agriculture and meet WTO obligations. Green box support includes income support not related to production decisions , environmental and land retirement program payments, domestic food aid, research and extension services, and export promotion programs like the MAP. Over 80 percent of U.S. domestic support for agriculture in 1998 was defined as “green box” by the USDA in 1998 .From 1995 to 1998, U.S. aggregate measure of support to agriculture declined while Green box support grew slightly.While the rules for some of the environmental programs, in particular the CSP, are still being developed, in general, environmental payment programs can be designed for inclusion in the WTO green box, making increased funding for these programs attractive. Domestic support qualifies for the WTO green box if the measure, is paid for by federal government revenues , does not provide price supports, and does not distort trade or has minimal effects on trade. Environmental payments in particular must be limited to the extra cost or loss of income incurred as a result of participation in the program. Some authors have argued that, whatever its merits as a negotiating position, subsidies for agriculture as a means of generating desirable joint outputs or environmental benefits is poor public policy . This is principally because subsidies for agriculture or payments to agricultural producers for environmental services do not directly target the production of the desired nonfood outputs but do so indirectly.

In general, less transparent programs lacking clear environmental goals are unlikely to be cost-effective means of achieving desired environmental outcomes. Bohman et al. give the example of beautiful meadows to illustrate this claim. Meadows are desirable, and one way of creating them is to provide support to dairy farmers; in this case, meadow existence is indirectly supported. A more transparent policy, more closely targeted to meadow creation, would be to compensate people for maintaining meadows. Dairy farmers may or may not be the most efficient providers of the desired good. More generally, other social objectives can be accomplished by broader development initiatives , and environmental externalities can be internalized through targeted and transparent regulations and taxes. The key empirical question, on which further research is needed, is which desirable nonfood outputs are genuinely joint outputs of food production, and which of these would be supplied at a socially inefficient level if food production were not subsidized . Too often, proponents of multi-functionality may overstate the extent to which positive environmental or social externalities are truly joint outputs of food production as an excuse to avoid the politically difficult task of reducing subsidies to agriculture. Environmental goals might be more cost-effectively achieved with policies not intended to subsidize agriculture.California agricultural producers cannot all win from increased trade liberalization. Ending government support for agriculture and lowering tariff barriers will inevitably benefit some more than others. On the whole however, California producers sell high value competitive products, and their major markets, especially Japan and the EU,cannabis plant growing remain protected and difficult to penetrate. Coordinated liberalization that affords California increased access to these markets, even if at the expense of increased competition from China and Mexico, could be an important opportunity. This is all the more true because most of California’s agricultural producers have few subsidies to give up. Even the loss of the export promotion programs would not be very costly; these programs provide little benefit to the industries they support. Because California agricultural producers as a whole stand to gain from global trade liberalization, if the 2002 Farm Bill jeopardizes the possibility of wide ranging reform at the WTO, it may be correct to conclude that the Farm Bill was costly to California farmers. Negotiations are currently stalled; largely over disputes about government support to agriculture in the U.S. and EU. The international response to the 2002 Farm Bill has generally been negative; the Bill has been characterized as politically motivated, and a violation of the spirit, if not the law, of the U.S. commitment to reduce domestic subsidies for agriculture undertaken in the URAA and at the commencement of the Doha round of negotiations.

It does appear that the U.S. will not violate its support cap of $19 billion as a result of the 2002 Farm Bill , although this depends on whether the U.S. commits explicitly to reducing support outlays in the event that a violation appears likely. Yet there is some suggestion that the moral authority of the U.S. as a proponent of liberalization at negotiations has been compromised. Others argue that new provisions of the Farm Bill may represent bargaining chips that can be used in negotiations to encourage other developed countries to reduce their own support for agriculture . The current U.S. negotiating position, announced in July 2002, proposes further tariff reductions, an end to export subsidies and a somewhat tighter cap on amber box domestic support . Despite the negative international reaction to the Farm Bill, there remains a relative consensus, at least in the popular press, that the EU’s CAP is possibly more damaging to developing country agriculture than U.S. farm policy. In addition, as recently as January 2003, the French government reaffirmed its commitment to protect French farms from international competition. It is difficult to predict how this unapologetic stance, in contrast to the continuing claims by U.S. representatives at the WTO that their country is committed to reform, will impact WTO negotiations. The U.S. balancing act between a stated commitment to trade liberalization at the WTO and the 2002 Farm Bill also contrasts with the position of the Cairns Group of countries at the WTO.17 The Cairns Group countries , provide little domestic support for agriculture and are relatively competitive producers expected to benefit from trade liberalization. The Cairns group has called not only for substantial reductions in distorting domestic support and an end to export subsidies, but also a stricter interpretation of the rules for including support measures as green box support. The group’s negotiating proposal states that “since the conclusion of the Uruguay Round the green box has been abused” .18 Certainly, it is plausible that, even if individual programs in a country’s green box claim do not distort trade, the total level of green box support may do so. Given the wide differences between the visions of the EU and the Cairns Group, with the U.S. somewhere in between, trade negotiations will continue to be difficult. 19Government influences agriculture everywhere. This chapter reviews some of the most significant governmental programs that influence California agriculture and highlights similarities with and differences from agricultural policy elsewhere. The chapter describes government programs that support California commodities and attempts to quantify that description. We present new producer support estimates building on the work of Sumner and Hart. Federal government programs and some California state programs support California agriculture. The central legislative basis for federal farm programs is now the Farm Security and Rural Investment Act of 2002 . The law affects program crops and provides a framework for government support of some conservation programs that affect a wider array of commodities. We also discuss the implication of implementation of the Uruguay Round Agreement on Agriculture , which became effective in 1995. Federal budget outlays that support California agriculture are also covered. The most important of the California state policies that we cover is the milk marketing order. However, we also discuss other state marketing orders and state outlays for agricultural support.Other chapters in this book have dealt with environmental and resource policies that are particularly important in California. Labor market policy is also important and the subject of a separate chapter. Here we focus the discussion mainly on farm commodity programs, but other governmental policies that provide support to agriculture are also included in the review. As noted throughout this book, one of the most striking aspects of California agriculture is the breadth of commodities produced. This breadth makes it nearly impossible to deal with each of the policies or programs that may be important for government support for agriculture. We highlight major programs that affect the most important handful of the commodities grown commercially in the state. Government’s overall effect on agriculture includes the impacts of a variety of policies that affect business in general. These policies include taxes on sales, income, excise, and real estate property, as well as provisions of infrastructure, education, and other government services. In addition, regulation of certain other businesses may affect agriculture indirectly. While these general policies pertaining to business may be important, they will be dealt with here only to the extent that agriculture is treated differently from other industries.

The lower endorsement of the two trauma items and one schizoid personality item may be the result of the stigma that is associated with abuse, specifically sexual abuse, and severe mental illness, e.g., being afraid of being crazy. For social support, participants indicated that a majority felt they had family members who they could talk to and rely on. Similarly high was the frequency for having peers to hang out with and not talk about work or family issues. Overall, nearly all participants indicated at least one form of social support. That is, they said yes to at least one or more items on the survey. Affirmative responses for substance problems were calculated for answers that indicated some lifetime use. For example, positive answers to using substances one year ago or more recently were coded yes. The majority of participants said that alcohol and other drug use never made them feel depressed or experience any other kind of psychological problem. Half of the participants indicated that they used AOD weekly or more often in the past 2-12 months compared to a third saying they were trying to hide AOD use, and parents or others complained about their AOD use for the same time frame. Irrespective of a time frame, a majority of participants reported using AOD weekly, and indicated that others were complaining about their AOD use at some point in their lives. Therefore, it appears that a large proportion of the sample showed problematic substance use behaviors or substance problems. Table 1 represents the percentages of affirmative responses to the study items.In order to address hypothesis 2.1, a CFA determined whether the measurement model for trauma,growing cannabis outdoors schizoid personality, social support, and substance problems was valid for the youth offender sample. A CFA was performed on the entire sample using the factor structure indicated by previous research.

The aim of the CFA was to validate the four-factor structure for the sample; that is, it served to reveal whether the four latent constructs can be measured by the observed variables or survey items. The trauma factor was specified by eight indicators, all of which comprised a sub-scale of past traumatic experiences on the GAIN General Victimization Scale. Schizoid personality consisted of six indicators, all of which reflect criteria of the DSM-IV-TR and relevant case studies . Substance problems were measured by five indicators of the recency of problematic drug-using behaviors. Social support was measured by nine indicators capturing different sources of support at school, work, home, or outside of school. Each indicator had an error term indicated by the small error pointing to it as depicted in Figure 1. The error on the indicator reflects variance that is not explained by the latent factor. Factor loadings were considered adequate for values greater than 0.30 . The unstandardized factor loading of the reference variable for each factor was set to 1.0, while the remaining variables were allowed to be freely estimated. The following goodness-of-fit statistics helped to determine adequate model fit: the comparative fit index , the Tucker-Lewis Index , and the root-mean-square error of approximation were consulted. CFI and TLI values close to .95 , and RMSEA values below .08 were considered adequate . The chi-square fit statistic was examined but given less weight in determining fit because of its sensitivity to sample size and the increased likelihood for committing a type I error . Modification indices were requested in order to assess whether correlating any indicator error terms would improve overall fit. Decisions for modifications were based on the value of the modification index, the standardized expected parameter change, parsimony, and general fit. Good model fit demonstrated how well the estimated variance-covariance matrix resembled the observed variance-covariance matrix.

Good model fit indicates that the model is appropriate to detect observed relationships and that it is able to explain a large percentage of the endogenous variables. Moreover, parsimony is a critical component of a good model since highly complex models have less free parameters and tend to have more constraints. Finally, the weighted root-mean-square residual , which is a relatively new fit index, was not considered to determine the viability of the model because of a lack of established research on it. A SEM model was specified in which psychological trauma was hypothesized to have an indirect effect onto substance problems and a direct effect on schizoid personality. Another path was modeled from schizoid personality to social support and to substance problems. Social support had a direct regression path onto substance problems. Together, trauma, schizoid personality, and support, were modeled to predict substance problems. All modeled relations are depicted in Figure 2. Factor loadings specified for each factor were allowed to be freely estimated, except for the reference indicator for each factor that was constrained to be 1.0 as part of unit-loading identification. Akin to the CFA, WLSMV was used as an estimation method, which was selected in the presence of dichotomous indicators in Mplus. Since model fit was good, no modifications were made. Results for research hypotheses 3.1-3.5 show that the following path coefficients were significant in the hypothesized direction: trauma significantly and positively predicted schizoid traits when controlling for social support and substance problems. In other words, an increase in one standard deviation in trauma yielded a .53 standard deviation increase in schizoid personality characteristics. This supported hypothesis 3.1. The effect size suggested that trauma explains 28% of the variance of the schizoid personality factor.Another set of findings is related to the viability of the constructs of trauma, support, personality, and substance problems when applied to the youth offender population.

Many of those constructs have been primarily employed with non-offending youths or adults, so that it was important to test whether they would work equally well with this sample before moving into the structural model analysis. Results show that these constructs worked well for assessing personality and risk constructs among youths on probation, and that these constructs are interrelated in meaningful ways. This suggested that the subsequent analysis of direction and significance of the paths between them could be conducted. The relations among the four constructs were examined. It was hypothesized that trauma would have a direct, positive, and significant effect on the development of schizoid personality traits. This hypothesis was confirmed. It was hypothesized that schizoid personality would negatively impact social support due to interpersonal difficulties that result in social withdrawal. This was confirmed by the significant, negative association schizoid personality had on social support. In other words, the more schizoid traits an adolescent endorsed, the less likely he was to have different types of support at school or home. It was also hypothesized that social support would decrease substance problems. This hypothesis was not confirmed. That is, for this sample having access to more and different types of support ranging from school counselor to parents did not decrease AOD use. It was hypothesized that schizoid personality would have a positive, direct,growing cannabis indoors and significant effect on substance problems. This was confirmed because higher levels of schizoid traits predicted higher AOD use. Similarly, the hypothesis of trauma having an indirect, positive relationship with substance problems was confirmed. Trauma had an indirect, significant, positive association with substance problems providing evidence for the role of childhood abuse adversely affecting AOD use behaviors in adolescence. This effect was found for the traumaschizoid pathway only but not for the trauma-schizoid-social support pathway. This implies that substance problems share a pathway with trauma and personality. As a consequence, the epidemiology of substance problems should encompass traumatic experiences as well as personality traits. The conceptualization of problematic underage AOD behaviors requires a multifaceted model that accounts for the association between intrapsychic factors and extrapsychic outcomes. This study explored whether social support decreases the association of schizoid personality with substance problems.

In the literature social support in the form of parental support was found to decrease adolescent substance use by instilling healthier coping mechanisms and better self-control . The measure of social support used in this study did not focus on only one type of support but included a variety of sources to which youths have access; i.e., teachers, parents, friends at school, and friends at home as well as hobbies. Assessing different forms of support including instrumental and emotional support, the hypothesis was not confirmed. For individuals with schizoid traits having different sources of social support did not ameliorate the negative trajectories of childhood trauma to substance problems. Particularly, social support did not act as a resilience factor in the trauma-schizoid-substance problems pathway. Over one third of the participants responded to items on the schizoid personality scale indicating that they did not care to be around people, and they did not feel emotional about people. Besides, twice as many reported not trusting most people, wanting to get even, and space out the world. These findings carry implications for counselors, as well as for probation officers, courts, and school personnel. The endorsement of several schizoid items clearly indicates a differentiated personality profile from the antisocial type. This overlooked type presents with a complex affective, cognitive, and behavioral profile that is shaped by past trauma and personality traits that require a special set of interventions. High levels of introversion, mistrust, and emotional detachment are qualitatively different from the emotional coldness of the so-called psychopath . A person with such a profile is likely to have a rich inner life created in an attempt to compensate for failed relationships with caregivers that is not accessed via conventional AOD treatment. Even though early traumatic experiences do not inevitably lead to personality disorders, they impact the way individuals see the world and others. Hence, assessing for personality traits should not be minimized to diagnostics, but serve the need for a greater understanding of the individual client. Research finds that relational trauma between child and caregiver has long-lasting effects on development . Childhood abuse is a risk factor for psychiatric disorders as it impacts the way individuals relate to others and the self . This is because the experience of abuse becomes internalized psychologically and physiologically in the form of brain function . Research on childhood trauma indicates that physical, sexual, and emotional abuse are associated with interpersonal hostility, low self-esteem, inadequate social functioning, and lower use of social coping strategies . From an object relations perspective, schizoid traits are the result of post-natal failures of loving relationships in which a strong sense of self was prevented from unfolding . Copious research has studied the relations trauma has with mental health and antisocial behaviors, such as substance abuse . Giaconia et al. found that as a result of affective, cognitive, and behavioral vulnerabilities trauma survivors are more likely to experience substance problems as well. This pathway was supported by the results of this study. This study also contributed an additional element, i.e., schizoid personality, into the conceptualization of the pathway between trauma and substance use. While schizoid traits in themselves are not pathological, having more of those traits in the context of trauma predicted substance problems. Hence, moving toward the higher end of the schizoid dimension poses a risk factor for problematic AOD use among youths who committed a crime, including trying to hide one’s use, using substances more frequently, and annoying others with their use. Psychoanalytic accounts of schizoid personality state that underneath the expressions of indifference and emotional coldness is a hunger for love and intimacy, a hyper-reflectiveness about the self, and a curiosity about others . This may help to conceptualize the relationship between schizoid traits and substance problems when thinking of AOD use as a way to numb the potentially distressing, unmet needs for interpersonal connectedness. Generally, results suggest that having experienced trauma in childhood is related to emotional detachment and psychological distress. This study was able to demonstrate that the effects of childhood trauma on personality can entail schizoid traits. Moreover, the alternative model demonstrated that when including personality in the model the direct effect between trauma and substance problems became non-significant, therefore providing empirical evidence for subsequent intrapsychic effects of trauma that led to maladjustment and not the occurrence of trauma per se. This corresponds to a resilience framework whereby maladjustment is not an irrevocable result but instead springs from the presence of additional risk factors that may have emerged from the original trauma. This work contributed to the resilience literature by examining the role of social support for different populations and personality types.

Object relations are interpersonal relationships that are part of a person’s most fundamental desire or libido because they strengthen the self . Objects can be thought of as actual persons that carry a maternal or caregiving role in a child’s life . Babies form a relationship to the world and subsequently to themselves by relating to an external object, i.e., the mother . In other words, relating to others is a behavior external to the individual that has an intrapsychic function. Object relations theory directs attention to disturbances in early parent-child interactions that negatively affect the child’s personality development and interpersonal functioning. Social relationships from a psychoanalytic account are far more than having someone to talk to; they are essential for developing self-regulatory mechanisms. Object relations are critical for developing an inner sense of self that can be distinguished from, yet that is related to, an outside reality . According to Winnicott children need to be reared in a “good enough” home with a mother or caretaker who adapts to the child’s needs and facilitates development. He notes that the mother’s preoccupation with the child’s needs is critical, so that the child experiences an omnipotent object that is strongly attuned to his needs until he is able to tolerate some frustrations without being traumatized by mother’s shortcomings . Recognizing the child’s needs and responding to the child’s internal processes by reflecting them back are essential caretaking roles that communicate emotional availability and interest . Adequate object relations in infancy are established by a variety of activities by the caretaker,cannabis grow table such as looking at the child, smiling, appropriate touching, and joining the child in his gaze or activity. Object relations theorists state that a child requires love, recognition, and attention from an object to develop a sense of self and reality of self.

If the caregiver fails to provide attunement to the child, he will experience this as a rejection regardless of the reasons for the lack of love . As a result the child internalizes the parent as a bad object who failed to meet his most basic needs. This leads to feelings of deprivation and inner emptiness . According to the British object relations school internal and external objects fulfill qualitatively different relationships; that is, the child who experienced frustrating external object relations is turning to internally generated fantasies of mergers and identification with the desired object . Hence, the libido for connection is turned inward toward objects of fantasy. It is this process that has great significance for the development of antisocial behaviors such as substance problems. Object relations theory adds to the biological model of addiction by claiming that impulses have to be met by a self-state. In the case of the schizoid personality type the self has become dissociated, so that drug addiction is a reflection of a dissociated self-state that once was yearning for love . Psychoanalytic self-psychology theorists have proposed that the parents’ or self-objects’ lack of mirroring and love can have long-lasting negative consequences for the development of the child, and it contributes to the development of schizoid personality disorder . The term self-object stems from Kohut’s self psychology theory that is related to object relations and emphasizes the “internal psychological experience of an object” . Mirroring is an important self-object function that serves to satisfy the child’s needs for recognition and praise . It helps the child develop a sense of reality of self that is worthy. Guntrip describes schizoid tendencies as a reaction to negative self-object relations.

Failures by the mother as the mirroring self-object put the child at risk for being traumatized due to experiencing a discontinuity of existence . Hence, from a psychoanalytic point of view the absence or inconsistency of parental adaptation to the child is a risk factor for the child’s self-fragmentation enhancing the vulnerability for maladaptive personality types. Fairbairn , one of the pioneers of the object relations school, studied schizoid personality intensely. He asserts that schizoid states stem from failed object relations that leave the child feeling unloved and rejected. The early rejection translates into a fear of closeness and true intimacy, and behaviors of withdrawal and chosen isolation . Individuals who experience schizoid states fear that their love will destroy the object because it is too consuming . They therefore prefer relying on internalized object relations and inner fantasies. They are able to role-play sociable interactions when necessary and can therefore easily be overlooked and underestimated in terms of their psychopathology and suffering. Similarly, self-psychology theory is helpful for understanding the emergence of personality and personality disturbances because it is concerned with “the self’s structural defects and shortcomings [in an interpersonal context]” . From that perspective a personality disorder results from insufficient self object responding to the child’s needs for “affirmation, merger, and idealization” . Affirmation is related to empathic attunement discussed earlier. Merger describes the experience of fusion of the self with a self object whereby the internal experience is temporarily fused with the external experience. Idealization, from Kohut’s perspective, refers to the three main areas of self, which are the “two polar areas” of the grandiose self, the “idealized parent imago” , and the “executive functions [that are] talents and skills” . The grandiose self is related to feelings of omnipotence and perfection, which can lead to narcissistic disturbances if they are not mirrored by the mother.

For example, a child who stands up for the first time needs to see pride in his mother’s eyes, a smile, and encouragement in order to satisfy an experience of self and of his potential. The child also maintains a feeling of omnipotence by projecting it onto his caregivers, which is called the “idealized parental imago” . The child’s idealizing expectations of the parent will unavoidably be frustrated, which will transform the child’s internalization to accept strengths and weaknesses in himself and others. For example, mother may not look at him every time he takes a new step or makes a discovery. Experiencing such frustrations within an overall caring, consistent care giving relationship helps the child de-intensify his grandiose self to enable more mature self object relations . Finally, the child needs the executive functions to achieve the ambitions represented by the grandiose self and the idealized parent. Ultimately,hydroponic cannabis system this will lead to productivity and meaning creation. Fair bairn notes that schizoid characteristics are an outcome of unsatisfying emotional bonds with parents and particularly with mother . This includes possessive and indifferent mothers who leave their children emotionally deprived, which causes regression to more primitive states for basic love need satisfaction. This more basic state may lead to depersonalization and “de-emotionalization” of object relations. As a result children may develop low distress tolerance and dependence in adult life. The traumatic experience that underlies schizoid characteristics stems from an emotional frustration because the mother does not love the child for himself and because she does not accept and value his love for her . This coins the child’s interpersonal style to adopt a distanced stance toward others since they are unable to fulfill his love needs. Intrapsychically, the child shifts object relations inside of himself where he relates to internalized others by incorporating or taking as opposed to giving and sharing. According to Fair bairn individuals with schizoid traits fear to give themselves emotionally to others because it feels to them like losing parts of their personality. They do not receive the same intrinsically motivating emotions from giving, such as creating values and self-respect . Another resulting feature from the relational trauma is the experience of inferiority due to not feeling loved in their own right . This sense of low self-worth may lead to a fixation on mother and narcissism as a defense against it . The schizoid character, albeit rare in the general population, appears to be relevant for the offender population. That is because it relates to antisocial behaviors in several ways: First, it is known that the prison population has elevated rates of trauma and dysfunctional family relationships that may foster schizoid traits; second, the process of identification with a bad object, i.e., the perpetrator of abuse, can lead to criminal behavior. Because the libido relates to parental objects, forms of abuse create inner conflict that can leave the child feeling ashamed.

By means of identification with a parent who abuses, the child develops a sense of badness . For Fair bairn whether a child becomes delinquent or not depends on several factors; the extent of internalization of the bad object in the unconscious, the degree of dysfunction of the object, the extent of identification with the bad object, and the ego defenses available to protect against acting out the bad object. Fair bairn makes an interesting and important point that a child may be motivated to engage in antisocial behaviors in order to release the repressed badness, and to protect the ideal image of his parents that appear good opposite to his badness. As a result, some of the character traits of schizoid personality may be considered defenses against a repressed, internalized bad object. In sum, parenting is critical in the child’s personality development because by serving as self objects parents help the child develop the affective and self-affirming structures it relies on for development and later functioning. Mirroring and idealization serve the narcissistic development and experience of omnipotence, which precede self-esteem and adaptation . When considering the experience of abuse by the hands of the caregiver or self object, it becomes apparent how devastating relational trauma can be for a child’s development. Surprisingly, differences in personality factors are rarely addressed in treatment allocation and intervention. This is astonishing provided that personality characteristics have significant influence on interpersonal and intrapersonal functioning that are central for recovery and rehabilitation. It is helpful to think of personality in dimensions to represent developmental levels and typologies . The dimensions can have substantial overlap, and people tend to oscillate along the dimensions because their functioning is impacted by stressors.The typology dimension captures the specific kind of defenses used, and helps classify them along the developmental dimension. For example, personality types using denial would be classified at the lower end of maturity and at the higher, more severe end of the typology. It is important to note that this study refers to personality types rather than personality disorders as listed in the DSM-IV-TR because it takes the participants’ developmental stage into consideration. Adolescence is a developmental phase in which personality is still emerging and traits are flexible. It is important to note that personality is conceptualized as a fluid construct consisting of propensities that undergo developmental changes and that are directly affected by stressors in the environment, such as poverty and poor family relations . Therefore, it is helpful to think of personality type as propensity or tendency, rather than a permanent set of thought and feeling patterns. Personality disturbances comprise of patterns of cognition, affect, impulse control, and interpersonal relationships. Individuals who suffer from personality disorders have inner experiences and perceptions that are often not mirrored by the outside world and do not meet society’s expectations and norms . Personality disturbances can therefore result in high levels of distress for the individual. Personality disorders like many other disorders occur on a spectrum of high and low intensities that include overlaps with other, related disorders. For example, schizoid personality shares symptoms of a lack of interest in personal relationships and emotional detachment with autism spectrum disorders. Furthermore, it is critical to diagnostically differentiate schizoid symptoms from contextual factors that affect an individual’s emotional style and behaviors. Growing up in disadvantaged neighborhoods and experiencing ethnic discrimination can cause individuals to display detachment and emotional indifference as a form of self-protection that should not be classified as a personality disturbance. Many individuals with schizoid personalities are highly functioning, hold jobs, and lead productive lives . A schizoid personality style describes individuals who tend to be introverted and solitary . Individuals high on this trait tend to be shy, avoid competitive relationships, and are described as eccentric . Individuals with schizoid traits display autistic thinking that entails daydreaming without a loss of a sense of reality . When confronted with an unpleasant stimulus, such as a disagreement, individuals with schizoid traits rather withdraw than express hostility .
