Over 1-in-4 young adults ages 18 to 24 report vaping nicotine in the past month.20 -22 Similarly, data from the nationally representative Monitoring the Future (MTF) study showed a more than 50% increase in cannabis vaping among 12th graders between 2017 and 2018 (4.9% to 7.5%),22 and other studies suggest increasing rates of cannabis vaping among young people who live in states where cannabis is legal.23 Most studies have focused on co-use of combustible tobacco cigarettes and combustible cannabis.24 -27 Despite the increasing popularity of vaping products, recent longitudinal studies have not considered their use when characterizing longitudinal patterns of T/C co-use in young people, which may lead to mischaracterizations with respect to longitudinal T/C co-use patterns.28,29 However, some recent cross-sectional work has begun to assess co-use with respect to vaping and other types of T/C products.
