Study: Medical Cannabis Laws Not Associated With Increased Use By Adolescents
(NORML) The enactment of state laws legalizing the physician-recommended use of cannabis therapy is not associated with increased levels of marijuana use by young people, according to data published online in the Journal of Adolescent Health.
Researchers at Rhode Island Hospital and Brown University assessed the impact of medical cannabis laws by examining trends in reported drug use by high-schoolers in a cohort of states before and after legalization. Researchers compared these trends to geographically matched states that had not adopted medical marijuana laws.
Authors reported overall “no statistically significant differences in marijuana use before and after policy change for any state pairing,” and acknowledged that some states that had adopted medical cannabis laws experienced a decrease in adolescent’s self-reported use of the plant. “In the regression analysis, we did not find an overall increased probability of marijuana use related to the policy change,” they stated.
