Alcohol is produced by the fermentation of yeast, sugars, and starches. It is a central nervous system depressant, and a drug that slows down the body and reaction times. It is rapidly absorbed from the stomach and small intestine into the bloodstream.
A standard drink equals 0.6 ounces of pure ethanol, or 12 ounces of beer; 8 ounces of malt liquor; 5 ounces of wine; or 1.5 ounces (a “shot”) of 80-proof distilled spirits or liquor (e.g., gin, rum, vodka, or whiskey) (NIDA).
Alcohol affects every organ in the drinker’s body and can damage a developing fetus. Intoxication can impair brain function and motor skills; heavy use can increase risk of certain cancers, stroke, and liver disease. Alcoholism or alcohol dependence is a diagnosable disease characterized by a strong craving for alcohol, and/or continued use despite harm or personal injury. Alcohol abuse, which can lead to alcoholism, is a pattern of drinking that results in harm to one’s health, interpersonal relationships, or ability to work (NIDA).
