What would happen if the drinking age was rolled back to 18 or 19? Initially, there would be a surge in binge drinking as young adults savored their newfound freedom. But over time, I predict, U.S. college students would settle into the saner approach to alcohol I saw on the one campus I visited where the legal drinking age is 18: Montreal's McGill University, which enrolls about 2,000 American undergraduates a year. Many, when they first arrive, go overboard, exploiting their ability to drink legally. But by midterms, when McGill's demanding academic standards must be met, the vast majority have put drinking into its practical place among their priorities.
A culture like that is achievable at U.S. colleges if Congress can muster the fortitude to reverse a bad policy. If lawmakers want to reduce drunk driving, they should do what the Norwegians do: throw the book at offenders no matter what their age. Meanwhile, we should let the pregamers come out of their dorm rooms so that they can learn to handle alcohol like the adults we hope and expect them to be.
