Medical marijuana laws and adolescent marijuana use in the United States: A systematic review and meta‐analysis

“Synthesis of the current evidence does not support the hypothesis that US medical marijuana laws (MMLs) until 2014 have led to increases in adolescent marijuana use prevalence. None of the 11 studies found significant estimates of pre–post MML changes compared with contemporaneous changes in non‐MML states for marijuana use prevalence among adolescents. In summary, current evidence does not support the hypothesis that MML passage is associated with increased marijuana use prevalence among adolescents in states that have passed such laws up until 2014.”  https://onlinelibrary.wiley.com/doi/full/10.1111/add.14136

“Medical Marijuana Hasn’t Affected Teen Pot Use: Meta-Analysis. Medical marijuana laws have had little impact on recreational pot use among U.S. teens, according to a meta-analysis of 11 studies dating back to 1991. The findings appear to debunk claims by opponents of medical marijuana that the laws have led to greater cannabis use among adolescents, wrote researcher Deborah Hasin, PhD, of Columbia University’s Mailman School of Public Health, New York City, and colleagues in the journal Addiction.”  https://www.medpagetoday.com/psychiatry/addictions/71342
