This study by Wechler H and Lee JE Gledhill-Hoyt et al, examined
student alcohol use and associated problems, including drinking
and driving, at Colleges in the U.S that ban alcohol for all students
In the spring of 1999, a nationally representative sample of students
(N= 11,303, 61% women) attending U.S. colleges completed questionnaires
regarding alcohol use and related behaviour. Responses from 2,252
students at 19 ban schools were compared with those of 9,051 students
at 76 non-ban schools.
Compared with non-ban schools students attending ban schools were
30% less likely to be heavy episodic drinkers and more likely
to abstain from alcohol. The lower rates of heavy episodic drinking
apply to students whether or not they were heavy episodic drinkers
in high school or not. Among drinkers, however, students at ban
schools engaged in as much extreme drinking as drinkers at schools
that do not ban alcohol and experienced the same rate of alcohol
related problems This suggests that the students continue to drink
elsewhere. Fewer students experienced second-hand effects of the
drinking of others at the schools that banned alcohol than did
students at non-ban schools.
A campus ban on alcohol may support abstention from alcohol use
at the College itself and reduce heavy episodic drinking and the
associated second hand effects in College. As it was a correlational
study it can not be determined whether the lower rates of heavy
episodic drinking were due to the ban or to other factors (e.g.,
self selection of students to those schools).
