The "culture of drinking" on U.S. college campuses has recently gained widespread national attention. A report by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) notes the disturbing consequences of drinking on campus each year: 1,700 college student deaths from alcohol-related causes; more than 500,000 unintentional injuries; more than 600,000 assaults; and more than 70,000 cases of sexual assault and acquaintance rape. Fraternities and sororities are among the key groups that foster this culture of drinking on campus. Given the high rates of heavy drinking in fraternities and sororities and the role they take in promoting frequent and heavy alcohol consumption on campus, college and university prevention efforts should target these social societies. Changing the availability of alcohol in the environment will be more easily achieved with the cooperation of fraternity and sorority leadership. College and university prevention specialists should implement the following five environmental strategies to reduce frequent and heavy drinking in fraternities and sororities: (1) Promoting Alcohol- and Drug-Free Social, Recreational, and Extracurricular Options and Public Service; (2) Creating a Social, Academic, and Residential Environment That Promotes Healthy Social Norms; (3) Limiting Alcohol Availability and Access; (4) Limiting Marketing and Promotion of Alcohol; and (5) Enforcing Campus Policy and State and Local Laws.
