That doesn’t jive with me being legal as an 18 year old in 1980? I know when I turned 18 and I know when I first bought beer at the store 3 weeks laterIt was a state law. The drinking age was 18 in 1978 and earlier. Then it was raised to 19 in the spring of 1979. Then the federal government threatened to take away funds from the states that did not raise it to 21 in 1984.
