Objectives:
Evaluate the association between perceived risk of harm and self-reported binge drinking, cigarette smoking, and marijuana smoking among college students.
Participants:
Participants were 599 students (ages 19-28) at a large Midwestern university recruited from October 2015 to December 2017.
Methods:
Hurdle regression was used to test the relationship between perceived risk of harm from substance use (i.e., binge drinking, cigarette smoking, and marijuana smoking), and self-reported use. Demographic characteristics were tested as moderators of this relationship.
Results:
Engagement in all three substance use behaviors was less likely when perceived risk was high. Age moderated the association between perceived risk and self-reported marijuana smoking with younger participants demonstrating a stronger relationship between perceived risk of smoking marijuana and self-reported marijuana smoking.
Conclusion:
Intervention programs will be most effective when perceived risk of substance use is high. Therefore, intervention programs should aim to increase college students' perceived risk of substance use.
