To examine intraindividual change in polytobacco and individual tobacco and nicotine product use across young adulthood. <\/jats:p><jats:p> Method. Participants were 2711 students from 24 Texas colleges participating in a 6-wave online study, with 6 months between each wave. Participants were aged 18 to 25 years at baseline in fall 2014 or spring 2015 and aged 20 to 28 years at wave 6. We used growth curve modeling for an accelerated longitudinal design to examine change from ages 18 to 28 years in polytobacco use (use of 2 or more products) and in use of 5 individual products (cigarettes, smokeless tobacco or snus, large cigars, cigarillos, or little cigars, hookah, and electronic nicotine delivery systems [ENDS]). <\/jats:p><jats:p> Results. There was a statistically significant decline in polytobacco use from ages 18 to 28 years. There were also statistically significant declines in ENDS, hookah, and cigar use but not in smokeless tobacco use, for which use was negligible, or in cigarette use. Importantly, cigarettes were the most used product at virtually all ages. <\/jats:p><jats:p> Conclusions. Young adults may mature out of polytobacco use with increasing age, but they may continue to use some products, most notably cigarettes, potentially the most toxic and addictive tobacco and nicotine product. <\/jats:p>","DOI":"10.2105\/ajph.2018.304850","type":"journal-article","created":{"date-parts":[[2019,1,24]],"date-time":"2019-01-24T20:58:51Z","timestamp":1548363531000},"page":"465-471","source":"Crossref","is-referenced-by-count":31,"title":["Trajectories of Tobacco and Nicotine Use Across Young Adulthood, Texas, 2014\u20132017"],"prefix":"10.2105","volume":"109","author":[{"given":"Alexandra","family":"Loukas","sequence":"first","affiliation":[{"name":"Alexandra Loukas and C.
