Substance-Induced Psychosis

Psychotic symptoms directly caused by intoxication, withdrawal, or long-term effects of substance use.

Full Definition

Substance-induced psychosis is a condition where psychotic symptoms (hallucinations, delusions, disorganized thinking) develop as a direct physiological consequence of substance use, intoxication, or withdrawal. Common causative substances include stimulants (methamphetamine, cocaine), cannabis, hallucinogens, alcohol, and certain prescription medications. The key diagnostic criterion is temporal relationship between substance use and symptom onset, with symptoms typically resolving as the substance clears from the system. Differential diagnosis requires careful assessment to distinguish from primary psychotic disorders that may be triggered but not caused by substance use. Documentation must specify the substance involved and temporal relationship to use.

Usage

Usage note: Always hyphenate 'substance-induced' when used as a compound modifier.
