A Longitudinal Analysis of Nicotine Dependence and Transitions From Dual Use of Cigarettes and Electronic Cigarettes: Evidence From Waves 1-3 of the PATH Study.
Electronic cigarettes (e-cigarettes) have gained popularity as a method to reduce conventional cigarette smoking, despite mixed evidence on their effectiveness. This study evaluates the relationship between overall and product-specific nicotine dependence and the transitions between dual use of cigarettes and e-cigarettes versus exclusive cigarette or e-cigarette use over time. ⋯ This study provides new evidence that established dual use and transitions to and from dual use are associated with higher tobacco dependence compared with remaining a cigarette- or e-cigarette-only user and that higher e-cigarette dependence is associated with becoming or remaining an exclusive user of e-cigarettes.
