The Impact of Marijuana Use in Patients With Psychosis

Kia Faridi MD, a psychiatrist at McGill University in Montreal, discusses the results of his study on the impact of marijuana use in patients with psychotic symptoms.¹ At the time of enrollment, 192 participants were ages 14 to 30 years, experienced at least 1 week of psychotic symptoms, and had not been previously treated with antipsychotic therapies. Results showed that marijuana users were more likely to experience continuous illness than those who did not use marijuana.
