Summary
Thirty-six states have legalized medical marijuana and 18 states have passed recreational marijuana laws (RMLs). Using data from the Youth Risk Behavior Survey (YRBS) for the period 1993-2017, Anderson et al[2] found that RML adoption was associated with an 8% decrease in the odds of marijuana use among high school students. These authors, had prelegalization and postlegalization data from only 7 states and pre– and post–recreational sales data from only 3 states, calling into question the generalizability of their results.[3]. Preand post-RML data from the YRBS are available from 10 states; 7 states contributed more than one Author affiliations and article information are listed at the end of this article
