Psychological Terms — Amphetamine Psychosis
Amphetamine psychosis describes a set of psychotic symptoms closely resembling schizophrenia that emerge following prolonged or excessive use of amphetamine or related stimulants.
Characteristic features include paranoid delusions, auditory hallucinations, agitation, and disorganized thinking. Because amphetamine increases dopamine availability in the brain, especially in mesolimbic pathways, the resulting overstimulation can precipitate symptoms similar to those observed in primary psychotic disorders.
The condition has historically been used to model psychosis in research settings due to its pharmacological similarity to schizophrenia. Symptom onset is typically dose-dependent and can occur after binge use or during withdrawal. Although symptoms often resolve with cessation and supportive treatment, severe or prolonged psychosis may require antipsychotic medication.
Amphetamine psychosis underscores the relationship between neurotransmitter dysregulation—especially dopamine hyperactivity—and psychotic symptomatology. Because of this overlap, clinicians must carefully distinguish between drug-induced and primary psychotic presentations, often through history taking, urine toxicology, and symptom course testing.
