A form of psychosis resulting from drug use is called?

• A. Substance-induced mood disorder
• B. Toxic psychosis
• C. Drug-induced psychosis
• D. Chemical encephalopathy

Answer: (C)

Drug-induced psychosis is when psychotic symptoms—such as delusions, hallucinations, or disorganized thinking—are directly caused by a drug. The key idea is that the psychosis appears in relation to the drug use or withdrawal and often improves once the substance is stopped or treated. Different drugs can trigger this, including stimulants like cocaine or methamphetamine, hallucinogens, cannabis at high doses, or alcohol withdrawal in some cases, and the underlying brain effects involve disruptions in neurotransmitter systems that regulate reality testing and perception.

Substance-induced mood disorder would involve mood symptoms (like depression or mania) driven by a substance, not primary psychosis. Toxic psychosis is an older or less precise term that can refer to psychosis from toxins, but the standard, specific label is drug-induced psychosis. Chemical encephalopathy describes broader brain dysfunction from toxins with cognitive and neurological signs, not primarily a psychotic syndrome.
