Adolescents and young adults who frequently use marijuana may be increasing their risk for psychotic symptoms later in life , say researchers based on findings of a recent study.
The study involved 2,437 young people between ages 14 and 24 for four years. Participants were examined for substance use, predisposition for psychosis, and psychotic symptoms. Results showed a moderate increase in psychosis later in life in adolescents and young adults who frequently used marijuana. Those with a predisposition to psychosis had an even stronger increased risk.
In conclusion researchers say Marijuana use moderately increases the risk of psychotic symptoms in young people but has a much stronger effect in those with evidence of predisposition for psychosis.
