This study aims to examine transitions in cigarette smoking among college students over 2.5 years and determine if the use of alternative tobacco products (ATPs) is related to these transitions. The results show that ATP use is significantly associated with transitions from never smoking to non-current smoking, from never smoking to very light smoking, and from non-current to very light smoking.
Background: High prevalence of very light cigarette smoking and use of alternative tobacco products (ATPs; i.e. electronic nicotine delivery systems [ENDS], cigars, and hookah) among young adult college students are causes for concern. The purpose of this study is to examine transitions in cigarette smoking (never vs. non-current vs. very light vs. heavier) among college students across 2.5 years and determine if the use of ATPs is related to these transitions. Methods: This study used six waves of data across 2.5 years from Project M-PACT. Participants who were 18-25 years of age at baseline were included in this study (n = 4,806). Cigarette smoking state was categorized as never smoking, non-current smoking [0 cigarettes smoked per day (cpd) in past month], very light smoking (< =5 cpd in past month), and heavier smoking (>5 in past month). Multi-state Markov models were used to examine temporal transitions in the four smoking states and examine the association of time-varying current ATP use with transitions in smoking states. Results: The probabilities of remaining in a smoking state decreased over time. The time-varying current ATP use was significantly related to increased odds of transitioning from never smoking to non-current smoking, from never smoking to very light smoking, and from non-current to very light smoking. Conclusions: Findings highlight the need to prevent ATP use among college students and in turn inhibit initiation and escalation of cigarette smoking.
