Drugs are found in foods, beverages and medication. Alcohol is a drug. It affects behavior after it reaches the brain. Alcohol is generally a depressant, not a stimulant, but sometimes a drinker imagines he or she is being pepped up.
Different people react differently to the same amount of alcohol.
Even the same person may react differently to the same amount of alcohol under different circumstances. An ounce of liquor contains about 70 calories. A 12-ounce can of beer contains about 150 calories. The flavor of the liquor does not affect drinkers. It is the alcohol content that affects them.
