Alcohol consumption by youth in the United States

Although the minimum legal age to purchase alcohol is 21 in all U.S. states and most territories (see: National Minimum Drinking Age Act), the legal details for consumption vary greatly. Although some states prohibit alcohol usage for people under 18, the majority have exceptions that permit consumption.

Underage drinking has become an activity primarily done in secrecy. In what is known as pre-gaming or pre-partying, underage drinkers may hide their alcohol consumption by drinking quickly before they go out. Brittany Levine explained in her article "Pre-Gaming" in USA Today that "of all drinking events involving pre-partying, 80% involved additional drinking afterward."
