Using a Markov multistate transition model, we estimated transition rates and one-year transition probabilities between never, non-current, ENVP-only, cigarette-only, and dual use among 5,292 adults aged 18\u201345 who participated in at least two of Waves 1\u201316 (February 2022\u2013February 2026), as well as overall transition hazard ratios by sex, age group, and race & ethnicity in a multivariable model.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n About 40% of individuals using cigarettes (39.5%; 95% CI: 36.9\u201342.0) or ENVP (40.1%; 95% CI: 36.4\u201343.7), and 60% of those using both products (60.8%; 95% CI: 58.3\u201363.2) were predicted to remain in those states after one year. Female participants began using cigarettes from never use (adjusted hazard ratio [aHR] 0.44; 95% CI: 0.29\u20130.66) or non-current use (aHR 0.65; 95% CI: 0.48\u20130.88) at lower rates than male participants. Participants aged 35\u201345 years initiated ENVP-only use from non-current use (aHR 0.34; 95% CI: 0.23\u20130.51) at a lower rate than those aged 18\u201334 years. Compared to non-Hispanic White participants, non-Hispanic Black participants initiated ENVP-only use from never use at a higher rate (aHR 4.39; 95% CI: 2.09\u20139.25).<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Rapid response surveys can provide important preliminary information on tobacco use transition patterns while we wait for the slower release of nationally representative survey data.<\/jats:p>\n <\/jats:sec>\n \n What this paper adds<\/jats:title>\n \n What is already known on this topic<\/jats:title>\n \n \n The use of electronic nicotine vapor products (ENVPs) has continued to evolve over time\u2014as well as attitudes towards them\u2014but the release of data from large nationally representative surveys often lags behind these changes.<\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:sec>\n \n What this study adds<\/jats:title>\n \n \n The Rutgers Omnibus Study provides rapid response data on tobacco use trends.<\/jats:p>\n <\/jats:list-item>\n \n Transition probabilities between tobacco use states remained relatively stable over time. Participants in this sample frequently switched between tobacco products, but those using both cigarettes and ENVPs were very likely to continue using one or both products.<\/jats:p>\n <\/jats:list-item>\n \n Female participants began using cigarettes at lower rates than male participants, participants ages 35\u201345 years began using ENVPs at a lower rate than participants ages
