Cannabis use disorder is a developmental disease.

A recent study looked closely at the chronic use of marijuana by adolescents, and found that there is a causal connection to psychosis. In the study by veteran cannabis researcher Jasmin Hurd, M.D. and colleagues, the study, "The developmental trajectory to cannabis use disorder" (to be published in the May issue of the American Journal of Psychiatry), senior author Hurd, working with lead author Jess Hinckley, M.D, an adolescent psychiatrist at Mt. Sinai Hospital in New York City, looked at the many harms of cannabis use to young people who are still developing. [ABSTRACT FROM AUTHOR]
