Cannabis use is associated with an earlier age of onset of psychosis and more severe impairments in neurocognition. Continued cannabis use after the onset of psychosis is associated with increased risk of illness relapse, longer hospitalizations, and more severe positive psychopathology. There is also evidence for superior efficacy of clozapine for reduction of substance use and negative symptoms in patients with schizophrenia and comorbid cannabis use.
