Teen Cannabis Use Rose in California Following Adult Legalization

Kaiser Permanente published research in JAMA Network Open showing that teen cannabis use in Northern California increased after California legalized adult recreational cannabis, reversing a multi-year declining trend. The study documented this uptick in adolescent consumption following the policy change, though teen use later declined during the COVID-19 pandemic. The findings suggest that adult legalization policies may have spillover effects on youth behavior despite age restrictions. The research contributes to ongoing debates about the public health implications of cannabis legalization for vulnerable populations.
