Canadian Researchers Say Mental Health Harm Increases with Cannabis Exposure


“A large prospective study of teens shows that “in adolescents, cannabis use is harmful” with respect to psychosis risk, study author Patricia J. Conrod, PhD, professor of psychiatry, University of Montreal, Canada, told Medscape Medical News.

This study was published in JAMA Psychiatry, Association of Cannabis Use With Adolescent Psychotic Symptoms, Bourque J, Afzali MH, Conrod PJ.”

“The effect was observed for the entire cohort. This finding, said Conrod, means that all young cannabis users face psychosis risk, not just those with a family history of schizophrenia or a biological factor that increases their susceptibility to the effects of cannabis.”

“The whole population is prone to have this risk,” she said.”
