Using national and state Youth Risk Behavior Survey (YRBS) data, we found no evidence of an association between medical marijuana laws (MMLs) and marijuana use among teenagers. In addition, we found a negative and statistically significant association between recreational marijuana laws (RMLs) and marijuana use.
