List of alcohol laws of the United States

In the United States, the Twenty-first Amendment to the United States Constitution grants each state and territory the power to regulate intoxicating liquors within their jurisdiction. As such, laws pertaining to the production, sale, distribution, and consumption of alcohol vary significantly across the country.

On July 17, 1984, the National Minimum Drinking Age Act was enacted. The Act required all states to either set their minimum age to purchase alcoholic beverages and the minimum age to possess alcoholic beverages in public to no lower than 21 years of age or lose 10% (Changed to 8% in 2012) of their allocated federal highway funding if the minimum age for the aforementioned is lower than 21 years of age. As of July 1988, all 50 states and the District of Columbia had a minimum purchase age of 21, with some grandfather clauses, and with the exception of Louisiana's complicated legal situation that was not resolved until July 2, 1996. Prior to 1988, the minimum purchase age varied by jurisdiction. After enactment of the Act, states not in compliance had a portion of their federal highway budget withheld. South Dakota and Wyoming were the final two states to comply, in mid-1988. Since the Act does not restrict the minimum drinking age or the minimum age to possess alcohol in private, most states continue to allow those under 21 to drink in certain circumstances. Examples are some states like Tennessee and Washington, which allow those under 21 to drink for religious purposes.
