Objectives: To explore demographics, contextual factors, and health risk behaviors associated with nondaily smoking by college students. Methods: In fall 2005, a random sample of 4100 students completed an online survey. Results: Of those surveyed, 29% reported current smoking; of that 29%, 70% were nondaily smokers. Compared to daily smokers, nondaily smokers were younger, African American (compared to white), had mothers with higher education, belonged to Greek organizations, and attended private (vs public) schools. Nondaily smokers were less likely to have used illicit drugs. Conclusions: Nondaily and daily smokers differed on several demographic and contextual factors, but reported mostly similar health risk behaviors.
