Between 2022 and 2024, researchers observed significant shifts in nicotine product habits among young adults in the United States. During this period, more than 16% of cigarette users transitioned to dual use of cigarettes and electronic nicotine delivery systems.
Why it matters
These transitions represent changing nicotine consumption patterns that affect how people manage tobacco dependence. Understanding these shifts is essential for assessing the long-term health implications of dual product use compared to exclusive use of either cigarettes or e-cigarettes.
A study of 24,756 adults analyzed transitions between cigarette and e-cigarette use from 2022 to 2024. Researchers found that 34.4% of users aged 18-24 shifted from dual use to exclusive vaping, compared to 29.4% of users aged 25-34.
The players
University of Michigan
A public research university where the lead researchers conducted this study on tobacco product adoption and usage patterns.
The details
The analysis utilized data from the Population Assessment of Tobacco and Health Study to track how nicotine users switch products over time. Researchers categorized participants by demographic factors to estimate transition probabilities, finding that intermittent smokers had a hazard ratio of 4.13 for transitioning to noncurrent tobacco use. These findings highlight how dual use acts as an intermediate stage in tobacco product trajectories.
Timeline
From 2019 to 2021, the transition rate to dual use was 4.0%.
During 2021-2022, the electronic nicotine delivery system initiation rate was 0.5%.
Between 2022 and 2024, 16.2% of young adults transitioned to dual use.
The study analyzed 23,803 participants from March 2021 through April 2023.
Findings were published in the American Journal of Preventive Medicine on September 14, 2026.
Health Landscape
This research updates the longitudinal data established by the Population Assessment of Tobacco and Health Study regarding tobacco trajectories. It provides a contemporary view of how young adults navigate the shifting landscape of cigarette and e-cigarette availability.
If you are currently using multiple tobacco products, it is worth discussing with your doctor how these patterns affect your cardiovascular and respiratory health. Your healthcare provider can offer evidence-based resources to help you address nicotine dependence.
The takeaway
The data indicates that nicotine use patterns among young adults are dynamic, with significant proportions moving between cigarette, e-cigarette, and dual-use states. Speak with your physician about creating a personalized plan if you are looking to discontinue tobacco or nicotine use.
