Abstract:
Research findings are inconsistent regarding a positive association between the passage of state medical marijuana laws (MML) and the adolescent access and the use of marijuana. We utilized a novel analytical approach to examine this issue with multiyear data from the 1997–2013 Youth Risk Behavior Surveillance System of the State of Michigan. After controlling for the historically declining trend in marijuana use prior to the passages of MML in Michigan, we found that marijuana use among adolescents had increased subsequent to the passage of state MML. The study findings suggest the need for considering the increased risk of marijuana use in adolescents, as more states have implemented laws permitting marijuana use.
