ABSTRACT Marijuana is the most widely used illicit substance among youths and recent epidemiological data indicate that rates of marijuana use are on the rise. The purpose of this study was to examine marijuana craving trajectories among adolescents in an eight-week, placebo-controlled pharmacotherapy trial targeting marijuana cessation. All participants received contingency management and cessation counseling, and were randomized to either N-acetylcysteine (1200mg NAC twice daily; n=45) or placebo (n=44). Craving for marijuana was measured using the short-form of the Marijuana Craving Questionnaire (MCQ). Results demonstrated a significant decrease in MCQ scores over time for the total sample, but no significant differential change in scores between the NAC and placebo groups. This lack of significant difference is in the setting of NAC participants submitting significantly more negative urine cannabinoid tests as compared to placebo participants. This suggests that cessation effects associated with NAC may be mediated by effects other than marijuana craving.

    ABSTRACT: Abstract Background and objectives: Tobacco and cannabis use are both highly prevalent worldwide. Their co-use is also common in adults and adolescents. Despite this frequent co-occurrence, cessation from both substances is rarely addressed in randomized clinical trials. Given evidence that tobacco use may increase during cannabis cessation attempts, and additionally that tobacco users have poorer cannabis cessation outcomes, we explored tobacco outcomes, specifically cigarette smoking, from an adolescent cannabis cessation trial that tested the efficacy of N-acetylesteine (NAC). Methods: Cannabis-dependent adolescents (ages 15-21; n = 116) interested in cannabis treatment were randomized to NAC (1200 mg bid) or matched placebo for 8 weeks. Participants did not need to be cigarette smokers or be interested in smoking cessation to qualify for inclusion. Results: Approximately 59% of enrolled participants were daily and non-daily cigarette smokers, and only differed from non-smoking participants on the compulsion sub-scale of the Marijuana Craving Questionnaire. Among cigarette smokers who were retained in the study, there was no change in cigarettes per day for either NAC or placebo groups during the eight-week treatment phase. Being a cigarette smoker did not appear to influence the effects of NAC on cannabis abstinence, though there was a trend in the placebo group of poorer cannabis outcomes for cigarette smokers vs. non-smokers. Conclusions: No evidence was found of compensatory cigarette smoking during this cannabis cessation trial in adolescents. Further work assessing interventions to reduce both cannabis and tobacco use in this population is greatly needed.

    ABSTRACT: Abstract Current marijuana use rates are the highest in the past decade and not likely to decrease given the legalization of marijuana for medicinal and/or recreational use. Concurrently, the nation is facing epidemic levels of obesity, cardiovascular disease and diabetes but little is known about the intersecting relationships of marijuana use and cardiometabolic health. The objective of this study was to explore emerging issues in context to the intersection of cardiometabolic risk and marijuana use. This topic has potential important implications for our nation's health as we relax our approach to marijuana but continue to have unacceptable rates of cardiometabolic illnesses.

    ABSTRACT: Medical marijuana is currently a controversial issue in medicine. There are strong pro and con opinions but relatively little scientific data on which to base medical decisions. The unfortunate scheduling of marijuana in class I has limited research and only serves to fuel the controversy. This article will review the history of laws to regulate drugs in the United States in the 20th century to provide context for the current status of medical marijuana. It will include the rationale for opposing medical marijuana laws and the problem of the Schedule I inclusion of marijuana as well as other drugs. It will examine the problems associated with smoking raw marijuana and review other routes of administration. Finally, it examines the inadvisability of medicine's promotion of smoked marijuana.
