Recent findings from national surveys indicate that marijuana use has been increasing in this population over the last decade with more than one-third of college students reported using marijuana in the past year. Researchers have shown that perceived normative support of others consistently predicts personal alcohol use among college students (Borsari and Carey, 2001). Especially for young adults, an individual’s perceived risk often accounts for significant variance in illicit drug use and is an important determinant of behavioral intention (Parsons et al., 1997). However, there has been little research on perceived support or risk as predictors of college marijuana use. For this study, the Core Drug and Alcohol Survey was administered to freshman living on campus in residence halls in a large southeastern university. Findings from this survey show that 21.9% of students reported using marijuana in the last year and 13.2% used the drug during the last month. Chi-Square analyses reveal that there was a significant relationship (X2=56.87, p<.001) between marijuana use in the last month and peer approval of regular use. For non-users, 68.3% felt that their peers strongly disapproved of regular use, while only 17.0% of marijuana users felt strong disapproval from friends. Similarly, perceived risk of regular marijuana use was significantly greater among non-users (53.7%) than current marijuana users (15.1%, X2=46.38, p<.001). Based on these findings coupled with the increasing use of marijuana among college students, colleges should address perceived risk and peer approval in their prevention efforts to reduce illicit drug use on campus.
