Legal drinking age and alcohol consumption

Abstract
Utilizing samples from two states, one where the legal age for the possession and consumption of alcohol was 18 (Louisiana) and one where the legal age was 21 (North Carolina), we examine the assumption that restricting access to alcohol results in lower alcohol consumption rates for the target population (age 18–20). We find little support for this assumption, but considerable evidence that restrictive legislation drives younger drinkers underground, resulting in overall higher consumption rates for the target population.
