Epidemiologic data suggests the smoking trajectory for some adolescents escalates rapidly and that tobacco dependence can develop quickly after initiation. In this study, we examine variation in cigarette consumption and individual characteristics associated with the rapid development of tobacco dependence, focusing particularly on the 24-month interval after tobacco initiation. The analysis is based on public use data files of the National Household Survey on Drug Abuse conducted in 1994-1996. Representative samples of adolescents aged 12-17 years old, totaling 13,831, completed a standardized interview assessing demographic characteristics, tobacco involvement and past year dependence, and psychological functioning over the preceding 6-month period as assessed by the Youth Self-Report. Analyses were restricted to the 1,734 youth who had started smoking within 0-24 months prior to being assessed, of which the onset for 70% of them was between 11-24 months. Logistic regression models took into account sample weights and used a variance estimation procedure appropriate for the complex multistage sampling design. Overall, 210 recent initiators met dependence criteria (13.5%, 95% CI = 12.0-15.2). Dependent smokers had greater cigarette involvement than youth who had not transitioned to being tobacco dependent by the time of assessment. Variation in mental health and sociodemographic characteristics were also detected. Disruptive behavior (p = .05) and being female (p = .02) were associated with being tobacco dependent. The rapid transition to dependence in youth depends not only on cigarette consumption features, but may also be associated with individual characteristics.
