A recent CDC study published in the Morbidity and Mortality Weekly Report uncovers a significant shift in adult tobacco use trends from 2017 to 2023. The prevalence of exclusive cigarette smoking declined by 5.2% (from 10.8% to 7.9%), while exclusive e-cigarette use surged by 20.3% (from 1.2% to 4.1%) during this period. These changes translate to a decrease of approximately 6.8 million exclusive cigarette smokers and an increase of approximately 7.2 million exclusive e-cigarette users.
