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 4,100 students completed an online survey. Results 29% reported current smoking, of which 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.
