2021 San Diego County Marijuana Prevention Initiative Report

California voters passed Proposition 64, The Adult Use of Marijuana Act, on November 4, 2016, legalizing the adult use and possession of marijuana. Retail sales of marijuana products began in 2018. The San Diego County Marijuana Prevention Initiative (MPI) published an initial report in early 2016 and a subsequent report in 2020. Previous reports included local marijuana-related trends to assess baseline data and identify important public health issues. This new report presents trends and public health data related to youth marijuana use and documents changes observed following legalization.
