IntroductionConcurrent use of cigarettes with alternative tobacco products (ATPs), even among very light smokers, may be harmful. This study examined current use of e-cigarettes, cigars, and hookah, and susceptibility to future use of these products in a sample of college student cigarette smokers.MethodsParticipants were 1161 18–29 year old (M age = 21.15; SD = 2.72; 52.7% female; 41.2% non-Hispanic white) current, or past 30-day cigarette smokers, drawn from a larger study. Current smokers were categorized as very light smokers [≤5 cigarettes per day (cpd)] and heavier smokers (>5 cpd).Results88.6% of all participating college student smokers were very light smokers and 67.7% used at least one ATP concurrently. The prevalence of current use in this sample was 42.9% for e-cigarettes, 36.4% for hookah, and 25.9% for cigars. Compared to heavier smokers, very light smokers were more likely to be younger, racial/ethnic minorities, and four-year versus two-year college students. Multilevel logistic regression models showed that after controlling for socio-demographic characteristics and substance use, being a very light smoker, compared with a heavier smoker, was negatively associated with concurrent e-cigarette use, but positively associated with concurrent cigar use, and not associated with concurrent hookah use. Moreover, compared to heavier smokers, very light smokers reported being more susceptible to future cigar and hookah use, but not e-cigarette use.ConclusionsConcurrent use of cigarettes with ATPs is popular among all college student smokers, but very light smokers are more likely than heavier smokers to use combustible ATPs. Smoking intervention programs and campus policies should caution smokers, especially very light smokers, against ATP use.
