About The Study: In this study involving 994,000 adults from U.S. states and territories, a slight decrease in the prevalence of current (past 30 days) e-cigarette use was found between 2018 and 2020. This decrease was mainly observed among young adults ages 18 to 20. In contrast, daily e-cigarette use consistently increased, particularly among young adults ages 21 to 24. This increase in daily use suggests greater nicotine dependence among those who use e-cigarettes, warranting continued surveillance.
