E-Cigarette Flavor Bans Spark Rise in Teen Cigarette Smoking.

In 2025, D Cheng and team analyzed data from the Youth Risk Behavior Survey and Behavioral Risk Factor Surveillance System to study how state bans on flavored e-cigarettes affected vaping and smoking. They compared states with flavor bans to those without from 2020 to 2023.

For adults aged 25 and older, e-cigarette use dropped from 17% in 2019 to 14% in 2023. But for teens (14-18) and young adults, cigarette smoking went up—by 1.8% for teens and 3.7% for young adults in 2021, with more increases later.
