Who chooses the drinking age?

Answer 1

The minimum purchase and drinking age is a state law. Each individual U.S. state establishes by law the minimum age at which an individual may purchase Alcoholic Beverages. The U.S. Government passed the National Minimum Drinking Age Act on July 17, 1984. This did not change the drinking age. However, it forced the individual states to establish the minimum drinking age as 21 or lose 10% of their federal highway funding.
