Medical Marijuana Laws Don’t Lead to Increased Teen Use
A new study published in the Lancet medical journal—the most comprehensive study of its kind to date—looks at adolescent marijuana use in states with legalized medical marijuana from 1991 to 2014. Using annual, repeated cross-sectional surveys of over one million teenagers, the study finds that marijuana use does not increase when states legalize medical marijuana.
The authors of the study write that “the risk of marijuana use in states before passing medical marijuana laws did not differ significantly from the risk after medical marijuana laws were passed.” The study finds that states with higher rates of teenage marijuana use before enacting their medical programs into law were unaffected by the new legal framework.
According to the U.S. Department of Health and Human Services, 40% of adolescents nationwide have tried marijuana at one or more times in their life. In Utah, that number is only 20%. As the new study indicates, based on indicators from over 20 other states, this number is unlikely to rise if Utah’s legislature allows a medical cannabis program.
While a slight uptick in teen use would not have justified denying sick Utahns the medical treatment they need, it is nevertheless a welcome development to have findings indicating that this concern—shared by some Utah legislators—is resolved.
