Objective: Because little is known about college-age smokers, the authors conducted a qualitative study to better understand this population. Participants: Forty college student smokers from 12 Pacific Northwest colleges participated in the study. Methods: The authors identified themes and built models to ascertain important factors related to smoking and smoking cessation. Four models emerged: smoking facilitators, smoking barriers, cessation facilitators, and cessation barriers. Results: The authors observed physical, psychological, and social influences across models, and social influences were strongly associated with both smoking and cessation. Many smokers were unlikely to define themselves as regular smokers. Most smokers had made prior quit attempts. Conclusions: College students are a unique category of smoker and colleges can play a role in helping them achieve cessation. (Contains 4 figures.)
