Abstract
Results from the 2009 National College Health Assessment were analyzed by gender and sexual orientation for college students’ nonmedical use of prescription drugs. Male and female students identified as having a minority sexual orientation (gay or bisexual) were significantly more likely to use nonmedical prescription drugs than heterosexual students. College students with a minority sexual orientation were engaged in more high-risk substance using behaviors than their heterosexual peers. Implications for assessment, counseling, and future research are discussed.
