Living off-campus - either independently or with peers - is a risk factor for heavy drinking and consequences. This group exhibits more risky drinking behaviors and alcohol-related consequences than students living on-campus, independent of age and class year. Therefore, students moving off-campus may be appropriate targets for alcohol misuse prevention programs.

Individuals with the greatest risk of initiation of vaping cannabis during the first year of college are those with a prior history of other cannabis use and ENDS use and who have peers in their network who initiate cannabis vaping.

This study provides strong evidence that perceiving that close peers drink heavily is particularly risk-enhancing for anxious and depressed college students, and offers implications about alcohol intervention targeted at these subgroups.
