Members of Greek-letter societies are the heaviest drinkers on college campuses, and experience more alcohol-related problems than their peers. This study reports the results of a web-based survey administered to stratified random samples of college students from 10 North Carolina universities. Greek-letter status was a significant independent risk factor for increased injury (both experienced and caused to others), even after adjusting for drinking behaviors. Prevention, screening, and intervention strategies are discussed in the context of these results.
