Summary
For many patients with schizophrenia, substance use predates the first psychotic episode. Patients suffering from their first psychotic break are more likely to be daily cannabis users and have a higher rate of tobacco use [1, 2]. Cannabis appears to exert a dose-dependent effect on the risk of developing a psychotic illness and illness onset is earlier [3]. Methamphetamine may increase the risk of schizophrenia on a par with cannabis [4]. Overall, 13–51% of patients entering treatment with their first psychotic episode have a co-occurring substance use disorder [5]. If substance use continues in parallel with a first-episode psychosis, patients fare more poorly in both the short and long terms.
