Abstract
Background and Objectives
Marijuana is the most commonly used illicit drug among college students, with heavy use leading to negative outcomes. Use of marijuana for medical and recreational purposes in select U.S. states has been controversial, with concerns surrounding increased prevalence rates and harm. The current exploratory study aimed to assess marijuana use in college students in Colorado, demographic differences in frequency of use, and motives for using.
Methods
College students (N = 300; 61% female) were recruited through introductory psychology courses and completed a series of questionnaires and a marijuana urine screen.
Results
Almost three‐fourths of the sample reported lifetime use of marijuana. Sixty‐five percent used marijuana within the last year and 29% tested positive on the urine screen. Hurdle Poisson regression models with a subset of participants (n = 117) showed non‐Greek and freshman status were associated with increased number of days participants used marijuana in the last month. Problem marijuana use was positively associated with a range of motives—of note—motives focused on coping, boredom, alcohol, and food.
Conclusions and Scientific Significance
Prevalence rates of marijuana use were high in this sample of college students in a state with legal recreational marijuana use. Particular students (eg, students who use marijuana to cope) may be at higher risk for problem marijuana use. Developing effective, tailored interventions for university students is warranted.
