THIQ is a biochemical compound found in the brains of alcoholics that is closely related to heroin. A scientist discovered THIQ in the brains of homeless alcoholics who had died. THIQ is produced when the body breaks down alcohol consumed by alcoholics, but not by social drinkers. THIQ accumulates in the alcoholic brain over time and is highly addictive, eventually causing the alcoholic to lose control over their drinking. The discovery of THIQ in alcoholic brains provides evidence that alcoholism is a disease, not a moral failing, and can be treated rather than punished.
