“This study examined whether Medical Marijuana Laws (MMLs) and their restrictiveness affect varying current adolescent alcohol and marijuana use behaviors using Youth Risk Behavioral Surveillance System data from 45 states between 1991-2011, including 12 of the 16 states that enacted MML on or previous to 2011, representing the most liberalized categorization of marijuana laws prior to the wave of recreational marijuana legalization laws that began in 2012. It is not well known how MMLs affect alcohol use behaviors, even less so for the adolescent cohort. This study found that states that enacted a MML, and having a less restrictive policy, were associated with lowered odds of current adolescent alcohol use. A unique feature of this study is the analysis of not only the effect of having any MML on these outcomes, but also the effect of state MML restrictiveness, using policy taxonomy scores. The alcohol findings are not as surprising given that Monitoring in the Future, a national surveillance of youth substance use, reports steadily annual declining alcohol use rates among youth from 1991 to 2011. By contrast, prevalence of marijuana use has remained steady from 1994 to 2014, despite a changing marijuana reform landscape.”
