Amongst college students, could a close friend that misuses prescription drugs predict an individual’s own misuse? A recent study aimed to answer this question, as well as identify other predictors of prescription drug misuse. The study administered an electronic survey to 279 college students enrolled in a class at a large southeastern university. Participants self-reported past-year use of any prescription drug without a written prescription, as well as reported the frequency of prescription drug misuse by their ten closest friends. Between 2012-2013, 24.6% of participants self-reported misuse of prescription drugs, with the majority misusing prescription stimulants. After controlling for this misuse, logistic regression analysis predicted that if a participant’s close friend misuses prescription drugs once, the participant is 1.4 times more likely to misuse themselves. Although this association was statistically significant, the authors could not establish causality—perhaps participants select friends with similar attitudes toward prescription drug misuse. Take-away: Even with these limitations, prevention and recovery specialists shouldn’t underestimate the influence of one’s social network. Consider this finding—in this study, 70% of all participants reported not having a friend that misused prescription drugs.
