What is Alcohol?
Ethyl alcohol, or ethanol, is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars, and starches. It is a central nervous system depressant that 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).

Who is at risk most?
According to a National Survey on Drug Use and Health (NSDUH) report, 26.6% of youth ages 12 to 20 reported drinking in the month before they were surveyed and 8.7% of them also purchased their own alcohol.
