Abuse of methamphetamines, cannabis, cocaine, and newer synthetic drugs (cannabinoids, cathinones) can trigger acute psychotic episodes that resemble psychotic disorders. The severity of substance use and addiction correlates with the likelihood of developing psychosis. Clinicians can identify some phenomenological features to help distinguish substance-induced psychosis from a primary psychotic disorder, though patients with existing psychotic disorders often abuse psychotomimetic drugs, complicating diagnosis. There is a notable lack of information on outcomes, treatments, and best practices for substance-induced psychotic episodes.
