Bureau of Economic Research, Inc. College campuses have
been cracking down on underage and binge drinking in light of recent highly
publicized student deaths. Although there is evidence showing that stricter
college alcohol policies have been effective at discouraging both drinking
in general and frequent binge drinking on college campuses, recent evidence
from the Harvard School Of Public Health College Alcohol Study (CAS) shows
that marijuana use among college students rose 22 percent between 1993
and 1999. Are current policies aimed at reducing alcohol consumption inadvertently
encouraging marijuana use? This paper begins to address this question
by investigating the relationship between the demands for alcohol and
marijuana for college students using data from the 1993, 1997 and 1999
CAS. We find that alcohol and marijuana are economic complements and that
policies that increase the full price of alcohol decrease participation
in marijuana use.
