Comorbid Cannabis Use and Mood Disorders Among Adolescents.

Adolescence is a unique developmental period marked by increased exploration and risk-taking, as well as important brain development milestones. Many people who use substances will begin using during adolescence, and cannabis is the most commonly used illicit substance among adolescents. For adolescents with mood disorders, cannabis use (and, by extension, cannabis use disorder) is even more likely, and the associated consequences are even more significant. In this review, we explore the assessment of cannabis use disorder among adolescents, the impact of cannabis use on mood symptoms, level-of-care recommendations for adolescents with comorbid cannabis use and mood disorders, and effective treatment options.
