A systematic review and meta-analysis published in the Journal of Psychiatric Research (2022) evaluated the risk of suicide attempt, suicidal ideation or suicide planning in individuals of 11–21 years of age who smoke cannabis.
Twenty studies reported suicide attempts in 34,859 young individuals, suicidal ideation in 26,937 individuals, and suicide planning in 9,054 young individuals.
The meta-analysis showed that cannabis smoking increased the risk of suicide attempt, suicidal ideation and suicide planning in young individuals of 11–21 years of age.
Youth cannabis use prevention programs and campaigns should address the potential risk for suicide among youth smoking marijuana.
