A Minimum Legal Drinking Age (MLDA) of 21 saves lives and protects health

Minimum Legal Drinking Age (MLDA) laws specify the legal age when an individual can purchase or publicly consume alcoholic beverages. The MLDA in the United States is 21 years.  However, prior to the enactment of the National Minimum Drinking Age Act of 1984, the legal age when alcohol could be purchased varied from state to state.1
