Section 1 of the Twenty-first Amendment expressly repeals the Eighteenth Amendment. Section2 bans the importation of alcohol into states and territories that have laws prohibiting the importation or consumption of alcohol. Several states continued to be "dry states" in the years after the repeal of the Eighteenth Amendment, but in 1966 the last dry state (Mississippi) legalized the consumption of alcohol. Nonetheless, several states continue to closely regulate the distribution of alcohol. Many states delegate their power to ban the importation of alcohol to counties and municipalities, and there are numerous dry communities throughout the United States. Section2 has occasionally arisen as an issue in Supreme Court cases that touch on the Commerce Clause.
