Objective: The purpose was to determine whether current cigarette smokers who also used smokeless tobacco (dual users) were more likely to quit or continue smoking compared to those who did not use smokeless.

Methods: Data came from Waves I and II of the National Longitudinal Study of Adolescent Health, using information from 3,284 current smokers (grades 7-11,169 grade 12 students were interviewed at Wave II) There is one year between Wave I and Wave II. Multivariate models were used to asses whether use of smokeless tobacco at Wave I was associated with continuation of cigarette smoking at Wave II, controlling for possible confounders.

Results: Among current cigarette smokers at Wave I, 14.5% used smokeless tobacco. Among smokers at Wave I, the proportion who reported continued cigarette smoking at Wave II was slightly lower among those who also used smokeless (73.5%) compared to those who did not(78.3%) (OR =0.71 [95% CI 0.52-0.98]. Females were more likely to continue smoking (OR = 1.29 [95% CI 1.00-1.67]) than males; African Americans (OR = 0.53 [95% CI 0.36-0.78) and Hispanics (OR = 0.65 [95% CI 0.47-0.89) were less likely to continue smoking than non- Hispanic Whites.

Conclusions: Findings are consistent with the conclusion that use of cigarettes and smokeless may not be related to continued cigarette smoking. Longer term follow-ups are needed in order to determine the stability of the relationship over time.
