This study’s findings rebut the repeated claims from prohibition supporters that the passage of medical cannabis laws increase teen use.

Scientists “found no evidence of intermediate-term effects of passage of state MMLs (medical marijuana laws) on the prevalence or frequency of adolescent nonmedical marijuana use in the states evaluated.”  Again from the study:  Difference-in-differences estimates suggested that passing MMLs (medical marijuana laws) decreased past-month use among adolescents … and had no discernible effect on the perceived riskiness of monthly use. … [These] estimates suggest that reported adolescent marijuana use may actually decrease following the passing of medical marijuana laws.”

For those readers who are research nerds, supporting data from peer reviewed medical literature can be viewed here, and here.

Medical marijuana laws do not increase teen use, rather it is the social use of cannabis in a black market setting that contributes to teen drug use.  Legal cannabis is the best way to protect our children from the black market.
