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 […]
Decriminalization of possession of allowable quantities of marijuana was assured statewide
In other words, workforce participation at age 23 is associated with lower marijuana-use rate over subsequent years for both males and females. This finding supports key concepts from the life-course theory which emphasizes salient life events such as employment or marriage to explain both continuity in childhood deviant behavior and changes during the life-course, and highlights […]
Substance use data were self-report and subject to recall bias
Education efforts about the adverse impact marijuana use can have on depression are needed, with a focus on subgroups at risk for poor outcome. Together, our results warrant replication and indicate a need for providers to ask depressed patients about their marijuana use, to inform those using marijuana of its potential risks and determine treatment needs. […]
This study was intended to inform local policy and practice in regulating marijuana to prevent youth
Furthermore, the number of dispensaries the cities in LA County have so far allowed may not have reached the threshold where their number has had an effect on the marijuana use behaviors of the adolescents who live/attend school there, but as licensing for recreational outlets proceeds the number of dispensaries in many LA County cities […]
The distance at which both lifetime and recent marijuana use
Proximity to dispensaries in neighborhoods has been shown to have a positive association with more frequent marijuana use among adults , but the effect of proximity to marijuana outlets to schools on adolescent marijuana use is unknown. Research Question #4 was: “Is the effect of dispensary bans on student marijuana use dependent on the distance of […]
The outcome variables were self-reported student lifetime and recent marijuana use
The independent variable was whether or not a city had a dispensary ban and was determined by the city policy that was in effect when the count of dispensaries per city was obtained in September 2016. The research question was broken up into three testable hypotheses: H2.1) there is a direct relationship between city dispensary […]
The extent to which these two measures may differ is dependent on enforcement
Visual cues to marijuana use such as billboard and magazine advertising for cannabis are strongly associated with adolescents’ intentions to use marijuana and eventual use . The presence of dispensaries may be analogous to advertising because many dispensaries in LA County use their exterior walls as advertising space like any other store . It is […]
