Adolescents who live in California may be more likely to use marijuana since adult recreational marijuana use was legalized in 2016, according to a new report in the Journal of Studies on Alcohol and Drugs.
"The apparent increase in marijuana use among California adolescents after recreational marijuana legalization for adult use in 2016 is surprising given the steady downward trend in marijuana use during years before legalization," says lead researcher Mallie J. Paschall, Ph.D., senior research scientist at the Prevention Research Center of the Pacific Institute for Research and Evaluation in Berkeley, California.

The researchers observed significant increases in the prevalence of lifetime and past-30-day marijuana use among nearly all demographic groups from 2017-2018 to 2018-2019 school years, after legalization of adult recreational use: an 18% increase in the likelihood of lifetime use and a 23% increase in past-30-day use. These numbers may reflect greater use of vaping products, and the overall increase was even more likely among those in demographic groups with historically lower rates of marijuana use.

Paschall says he can only speculate as to the reason, but that the greater increases in these normally low-risk groups may be attributed to marijuana use becoming more normative due to legalization, along with relatively greater overall declines in marijuana use among youth in historically 'high-risk' groups during the study period.
The study also indicated greater increases in the frequency of past-30-day marijuana use among older adolescents, males, African American and Asian youth who were regular users. There were notable increases in marijuana use frequency among adolescents in 2018-19, which may reflect national increases in the use of vaping products.
