Hallucinogen-induced Psychotic Disorder

This disorder involves hallucinations, delusions, or disorganized thought processes triggered directly by hallucinogen use. Etiologies include acute intoxication with hallucinogens such as LSD, psilocybin, or mescaline. Patients present with perceptual disturbances, agitation, paranoia, and disorganized speech. Diagnosis requires temporal correlation with substance use and exclusion of primary psychotic disorders. Management consists of immediate substance cessation, supportive care, and pharmacologic intervention with antipsychotics if symptoms are severe. Prognosis is generally favorable with early recognition and sustained abstinence.
