A Columbia University study has found that teens who use cannabis recreationally are two to four times as likely to develop psychiatric disorders, such as depression and suicidality, than teens who don’t use cannabis at all.
The research, published in JAMA Open Network May 3, also finds that casual cannabis use puts teens at risk for problem behaviors, including poor grades, truancy, and trouble with the law, which can have long-term negative consequences that may keep youth from developing their full potential in adulthood.
“Perceptions exist among youth, parents, and educators that casual cannabis use is benign,” said Ryan Sultan, MD, assistant professor of clinical psychiatry in the Department of Psychiatry at Columbia and lead study author. “We were surprised to see that cannabis use had such strong associations to adverse mental health and life outcomes for teens who did not meet the criteria for having a substance use condition.”
