Prevalence of Electronic Cigarette Dependence Among Youth and Its Association With Future Use

Question What are the prevalence, symptom presentation, and future vaping patterns associated with youth electronic cigarette (e-cigarette) dependence?

Findings In this cohort study of 444 youths aged 16 to 18 years with past-year e-cigarette use, 11.7% of youth reported experiencing at least 1 e-cigarette dependence symptom. While less common and severe than combustible cigarette dependence, e-cigarette dependence had a similar symptom profile and was positively associated with vaping continuation, frequency, and intensity 6 months later.

Meaning These findings suggest that e-cigarette dependence among youth may be an expression of tobacco use disorder that is associated with use escalation.
