A NIDA-funded study using Monitoring the Future data found that Greek life membership is associated with continued binge drinking and marijuana use through early midlife. A scientific study finds that close to half of residential fraternity members had symptoms of alcohol use disorder (AUD) by age 35, and that living in a fraternity or sorority at college is associated with continued binge drinking and marijuana use through early midlife. The research, from the University of Michigan, is published in the Journal of Adolescent Health and was funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.
