A problem facing American universities is heavy drinking by the student body which results in unintentional injuries and deaths, illegal offenses, sexual assault, altercations, and academic demise. The relationship between the type of alcohol policy enacted on campus and alcohol consumption among undergraduate students attending 4-year public universities in the Midwestern U.S. was investigated. The social ecological model provided the theoretical foundation for this study. A random sample of students from universities that have policies in place allowing the sale and use of alcohol in approved locations was compared to samples of students in universities that have policies in place prohibiting the sale and use of alcohol on campus. The Core Alcohol and Drug Survey was used to quantify drinking behaviors among students. Multiple logistic regression analysis was used to test the hypothesis that heavy drinking is associated with alcohol policy while adjusting for the effects of student characteristics. The type of policy in place (wet or dry) was not significant against the odds of heavy drinking (p = 0.323) after controlling for age, gender, ethnicity, participation in sports, and participation in Greek organizations. Gender, age, and participation in sports were associated with heavy drinking while participation in Greek organizations was not. This study provides insight into the relationship of alcohol policy type to heavy drinking. The reduction in the number of students who drink heavily could promote positive social change by reducing the number of negative consequences that are associated with heavy drinking for them and their friends, families, and communities.
