Association of Cannabis Use With Self-harm and Mortality Risk Among Youths With Mood Disorders

Youth with pre-existing mood disorders who also have cannabis use disorder (CUD) were found to have an increased risk of self-harm, suicide, and death by unintentional overdose and homicide. Youth in foster care and non-Hispanic Black youth were found to be at highest risk. This study is important in showing that reducing or eliminating cannabis use can protect our vulnerable youth with mood disorders. Additionally, studies show that increasing medical and statewide recreational legalization of marijuana has been associated with increased addiction in adolescents.
