“Data were collected via an online survey of participants in the Southern California Children’s Health Study from 2015 to 2016 (baseline) and 2016 to 2017 (follow-up) (N = 1312)…. Relative to never e-cigarette users, past-30-day e-cigarette use was associated with greater frequency of past-30-day cigarette smoking at follow-up. Among baseline past-30-day e-cigarette users, participants who used mods (versus vape pens) smoked >6 times as many cigarettes at follow-up (mean: 20.8 vs. 1.3 cigarettes; rate ratio = 6.33; 95% confidence interval: 1.64–24.5) after adjustment for socio-demographic characteristics, baseline frequency of cigarette smoking, and number of days of e-cigarette use.”
