How Underage and Adult Users Transition Between Nicotine Products? | #GFN26ScienceLab
10 Aug 2026
How do people actually transition between different nicotine products over time? Are young people who experiment with e-cigarettes more likely to become smokers, and is dual use a long-term pattern or simply part of the journey away from cigarettes?
Drawing on a decade of data from the U.S. Population Assessment of Tobacco and Health (PATH) Study, this presentation explores how nicotine product use changes among both underage and adult populations. Using longitudinal evidence that follows the same individuals over time, it examines real-world transitions between cigarettes, smoke-free products, dual use, and non-use.
