The University of Idaho is teaming up with the National Institutes of Health and other universities to rate strategies for combating underage drinking and alcohol abuse among students. About 41 percent of UI students engage in binge drinking, which is similar to national trends, said Sharon Fritz, who oversees the drug and alcohol programs at the university’s Counseling and Testing Center. Binge drinking is five drinks for a male, or four drinks for a female, within a two-hour period.
