“The findings of this cross-sectional study of US youths suggest that although the prevalence of current nicotine vaping declined during 2020 to 2024, the youth vaping population may have hardened over this period, evidenced by increasing daily use, more unsuccessful quit attempts, and shifting demographic profiles. Clinicians and policy makers should be mindful that youths with frequent vaping increasingly face unique challenges that may impact treatment and prevention efforts.”

Note: The “hardening” of e-cigarette use in the US is a pattern that should be studied in other countries since it has implications for prevention and treatment in other countries with substantial e-cigarette use. Stephen Hamann
