Studies demonstrate associations between nonmedical use of prescription stimulants (NMUPS) and depressed mood; however, relevance of NMUPS route of administration and frequency of use have not been examined. We hypothesized frequent NMUPS and nonoral routes would be significantly associated with depressed mood. A Web survey was self-administered by a probability sample of 3,639 undergraduate students at a large U.S. university. The survey contained substance use (e.g., frequency, route of administration) and depressed mood measurement. Past-year prevalence of NMUPS was 6.0% (n = 212). Approximately 50% of frequent or nonoral NMUPS reported depressed mood. Adjusted odds of depressed mood were over two times greater among frequent monthly NMUPS (adjusted odds ratio [AOR] = 2.3, 95% confidence interval [CI] = 1.01-5.15) and nonoral routes of administration (AOR = 2.2, 95% CI = 1.36-3.70), after controlling for other variables. Nonmedical users of prescription stimulants should be screened for depressed mood, especially those who report frequent and nonoral routes of administration.
