alcohol-related negative consequences occur frequently among undergraduates. For example, a large study of Canadian undergraduates estimated that a full 44 % of students reported one or more indicators of harmful drinking such as experiencing memory loss, suffering an injury, feeling guilty or having other concerns about their drinking [7]. An estimated 18–27 % of undergraduates will experience an alcohol use disorder in their lifetime [15]. In addition, one third of undergraduates report one or more indicators of dependent drinking such as being unable to stop drinking and needing a drink in the morning or hazardous patterns of drinking according to the Alcohol Use Disorders Identification Test [16]. This research suggests that a majority of students are negatively affected by drinking on campus [7], whether it is missing classes due to hangover (19 %), engaging in unplanned sex (14.1 %), driving (7.4 %) or unsafe sex (6.0 %) after drinking or experiencing negative consequences due to other students’ drinking such as being assaulted (10.0 %) or sexually harassed (9.8 %).
