Heavy drinking on college campuses: no reason to change minimum legal drinking age of 21

The recent Amethyst Initiative argues that a minimum legal drinking age (MLDA) of 21 has created a culture of heavy alcohol use on college campuses by making drinking clandestine and extreme. This group and others argue that lowering the MLDA will reduce the problem of "binge drinking" on college campuses. However, such a policy change would remove one of the most researched and supported policies in the nation's alcohol control arsenal. There is little evidence that other interventions or policies are capable of working on the same broad level as MLDA 21, and there could also be a deleterious ripple effect in related legislation because MLDA 21 works in conjunction with other drinking laws. In addition, historic and international experiences with a lowered MLDA indicate there are serious social and public health consequences. Instead of removing efficacious interventions, we must remain committed to implementing and enforcing evidence-based practices and legislation.
