As research continues, it will be important to include underrepresented populations as patterns of use for medical purposes may differ by socioeconomic status, race, and access to medical care. Despite the lack of evidence on the efficacy of marijuana use for health conditions, nearly half of those who disclosed medical marijuana use to their doctors […]

GfK created a representative sample of US adults by random sampling of addresses
However, most published studies have focused only on adolescents under the age of 18 years and do not reflect the adult population to which medical marijuana policies apply . Therefore, long-term longitudinal studies are needed to monitor the effects of marijuana legalization, marijuana initiation/ re-initiation, cigarette initiation/ reinitiation, and patterns of co-use across all age […]
Occipital deactivations are thought to relate to perceptual priming as information is reprocessed
To assess volume of activation within posterior parietal and left prefrontal ROIs, we calculated the number voxels showing significantly greater activation during SWM relative to vigilance for each participant within each ROI. We then performed regression analyses to predict volume of activation from age, gender, and their interaction. To determine whether movement during fMRI scanning might […]
Public hearings were subsequently held to elicit further public perspectives
After further review, involving the Planning Commission and additional public hearings, the county voted to permit marijuana production and processing establishments if they complied with notice provisions and strict zoning restrictions. On the eastern side of Washington state, the Spokane County Commission imposed a moratorium on outdoor marijuana farms in November 2016, because of residential complaints about […]
The risk pathway from anhedonia to marijuana use may be incremental to risk of other drug use
Although we report complete data for all analyses, meta analyses of cross-sectional studies examining cough, sputum production, and wheezing were limited by heterogeneity. Heterogeneity was likely related to the lack of uniform assessment of marijuana use and outcome ascertainment . Our current understanding of the long-term health effects of marijuana could be improved by standardized […]
The mechanisms for the causal connections between marijuana and OPR are not clear
It appears that the gaps in hospitalizations involving marijuana dependence and abuse were continuously widened between the states adopting and non-adopting medical marijuana policies with states adopting medical marijuana policies increased more sharply. Throughout the study period, the states with medical marijuana policies continuously had higher rates of hospitalizations related to opioid dependence or abuse. […]
We also conducted sensitivity analyses for different classification of marijuana use
Participants were invited to participate in 9 in-person clinic examinations over the study period . We used data from the first seven visits, up to year 20, as ECG measures were available at baseline, visit Year 7, and 20. Each participant who attended the examination received non-monetary gifts and monetary reimbursement to cover expenses. All […]
Field census is typically considered the gold standard in retail outlet research
Current research indicates that secondhand marijuana smoke contains many of the same chemicals as secondhand tobacco smoke and some in greater concentrations with recent studies demonstrating that secondhand marijuana smoke has negative cardiovascular effects similar to tobacco smoke.Non-smokers exposed to secondhand marijuana smoke had detectable levels of THC and metabolites, with levels increasing when higher potency […]
The impact of marijuana use on smoking behavior differs across the two schools
In a few instances the difference between these two variables is zero, which appears to be a reporting error as they reported all their usage in the last 30 days and yet that they started at a young age. We code them as a zero at t1 under the presumption that this earlier usage was very limited, […]
The mechanism by which marijuana may alter brain tissue during development remains unclear
Few group differences in cortical thickness were observed; the majority of areas were no longer significant after controlling for lifetime alcohol use. Thicker medial temporal lobe estimates were found in the user group at baseline and follow-up when ICV and lifetime alcohol use were controlled for. We observed subtle decreasing thickness estimates from baseline to follow-up in […]
