Alcoholic hallucinosis is a complication of alcohol misuse in people with alcohol use disorder. It can occur during acute intoxication or withdrawal with the potential of having delirium tremens. Alcohol hallucinosis is a rather uncommon alcohol-induced psychotic disorder almost exclusively seen in people with severe, recurrent alcohol use disorder (formerly known as chronic alcoholics) who have many consecutive years of severe and heavy drinking during their lifetime. Alcoholic hallucinosis develops about 12 to 24 hours after the heavy drinking stops suddenly, and can last for days. It involves auditory and visual hallucinations, most commonly accusatory or threatening voices. The risk of developing alcoholic hallucinosis is increased by long-term heavy alcohol abuse and the use of other drugs. Descriptions of the condition date back to at least 1907.
