Retain age-21 drinking age

All 50 U.S. states, the District of Columbia, and Guam currently prohibit anyone under age 21 from possessing alcoholic beverages; most states also prohibit those under age 21 from purchasing and consuming alcoholic beverages. Under this strategy, campuses and local and state governments support continuation of the age-21 minimum legal drinking age due to its effectiveness in reducing underage drinking consequences.
