Teens who use cannabis are more likely to have psychiatric disorders as young adults, according to “Adolescent Cannabis Use and Risk of Psychotic, Bipolar, Depressive, and Anxiety Disorders” by Kelly C. Young‐Wolff, Ph.D., MPH and colleagues. Published February 20 in JAMA Health Forum , the cohort study of 463,396 adolescents ages 13 to 17 years found a significantly increased risk of incident psychotic, bipolar, depressive, and anxiety disorders by age 26 in people who had used cannabis as teens. The researchers urged the importance of limiting youth exposure in the face of legalization.
