A recent study looked at marijuana and alcohol use in people between the ages of 18 and 24. It’s probably not surprising that the results show a drastic increase in alcohol consumption in people just over 21; after all, that’s the minimum legal age to drink. What an economist-researcher found remarkable is that, at the same age, there was an equally dramatic drop in marijuana use.
