Abstract

Is cannabis responsible for early onset psychotic illnesses?

Alain Dervaux,Marie-Odile Krebs,Xavier Laqueille

Several prospective studies in the general population and meta-analyses have consistently found that cannabis use is associated with an increased risk of psychotic disorders, in particular schizophrenia. Continued cannabis use over time increases the risk of psychosis in a dose–response fashion. A higher risk of schizophrenia is predicted by an earlier age of cannabis use.
