title: Do smokers of specialty and conventional cigarettes differ in their dependence on nicotine?
abstract: Specialty cigarettes, bidis and kreteks, have commonly been viewed by adolescent users as being less harmful than conventional cigarettes. Biochemical studies, however, have shown that the concentration and delivery of nicotine from these tobacco products are not insignificant. The current study tested whether the diagnosis and symptoms for nicotine dependence differed among conventional-only smokers (n=16 959), specialty-only smokers (n=313), and poly-tobacco smokers (n=1288) from the 2002 and 2003 National Surveys on Drug Use and Health. Compared with the specialty-only smokers, the conventional-only and poly-tobacco smokers were more dependent on nicotine, assessed by the Nicotine Dependence Syndrome Scale and a single item from the Fagerstrom Test for Nicotine Dependence. However, after accounting for differences in smoking frequency, the specialty-only smokers had significantly greater odds of being nicotine dependent than the conventional-only smokers. The reversed effect was primarily attributed to the specialty-only smokers who smoked less frequently, but reported a shorter time to their first cigarette. These findings suggest that the nicotine acquired from specialty cigarettes may be sufficient in yielding a sense of urgency to smoke.
