This is the opposite of drug tolerance , in which the effect or the subject’s reaction decreases following its repeated use. Alcohol Tolerance occurs when regular drinking or drug use causes changes in the brain’s function and structures, and the metabolism adapts to the regular presence of drugs in the body.
