In a meta-analysis published in the journal JAMA Psychiatry in 2019, researcher Gabriella Gobbi and colleagues analyzed findings from 11 studies including a total of 23,317 participants and found that cannabis use in adolescence (before age 18) was associated with a significantly increased risk of depression, suicidality, and suicide attempts in young adulthood (between 18 and 32 years of age).

The researchers did not find a link between cannabis use and anxiety.

Editor’s Note: Cannabis use is not as harmless as many teens may believe.
