The National Minimum Drinking Age Act of 1984 made it so that a state with a minimum drinking age below 21 would be subjected to a ten percent decrease in its annual federal highway apportionment, effectively setting the national drinking age to 21 years old.
Upon turning 18, United States citizens gain the ability to enter contracts, marry, vote, gamble, and even join the military, but are unable to legally purchase alcohol. Setting the drinking age to 21 does not prevented 18-20 year olds from drinking, but rather drives their alcohol use underground, making it more dangerous.
Please repeal The National Minimum Drinking Age Act of 1984, and allow the states to decide on their own drinking ages.
