The first LAI antipsychotics (often referred to as simply "LAIs") were the typical antipsychotics fluphenazine and haloperidol.

The mechanism of alcohol-related psychosis is due to distortions to neuronal membranes, gene expression, as well as thiamine deficiency. It is possible in some cases that alcohol abuse via a kindling mechanism can cause the development of a chronic substance-induced psychotic disorder (e.g., schizophrenia).
However, homeostatis does not explain how tolerance influences alcohol addiction in many cases. Epigenetic alterations, including phosphorylation, methylation, acetylation, miRNA, and chromatin remodeling, may help explain the cases not explained by homeostatic mechanisms. These epigenetic mechanisms have been studied in rodents.
Alcohol hallucinosis is a rather uncommon alcohol-induced psychotic disorder almost exclusively seen in chronic alcoholics who have many consecutive years of severe and heavy drinking during their lifetime. [3] Alcoholic hallucinosis develops about 12 to 24 hours after the heavy drinking stops suddenly, and can last for days.
In Brazil, pharmacological torture involved the injection of alcohol into the tongue in the 1940s, the injection of ether into the scrotum in the 1960s, and drugs were used to cause strong contractions in the 1970s. Also, muscle relaxants were used to minimize muscular rigidity and bone fractures caused by electric shock in the 1970s. [4] [2]
