Prevalence of withdrawal symptoms from electronic cigarette cessation: a cross-sectional analysis of the US Population Assessment of Tobacco and Health

Abstract

Electronic cigarette use can produce rapid and high levels of nicotine and thus could produce or maintain a physical dependence on nicotine. No experimental and limited observational studies have tested whether cessation of e-cigarettes is associated with withdrawal symptoms. To examine withdrawal from electronic cigarettes and compare it to that from tobacco cigarettes, we searched the US Population Assessment of Tobacco and Health Survey to locate successful and unsuccessful attempts to stop electronic or tobacco cigarettes. We examined electronic cigarette-only users, tobacco cigarette-only users and dual users. A minority of e-cigarette users who stopped/reduced e-cigarettes reported withdrawal symptoms but reported fewer symptoms than tobacco cigarette users who stopped/reduced tobacco cigarettes. E-cigarette withdrawal was not significantly greater in those who tried but were unable to stop e-cigarettes. In dual users, continued tobacco use appeared to reduce e-cigarette withdrawal but the opposite was not true. Given our small sample size and use of retrospective recall, an experimental test of e-cigarette abstinence is needed to better describe the severity of electronic cigarette withdrawal.
