Summary
Aim: To assess (1) how far smoking patterns, depression and smoking-related beliefs and intentions predict vaping uptake, current vaping and vaping frequency among daily smokers; and (2) how far the aforementioned predictors and baseline vaping frequency predict current vaping among those who reported ever vaped.Findings: Number of cigarettes smoked daily was associated with (1) subsequent vaping uptake (OR=1.69, 95%CI [1.19, 2.39] for 30+ cigarette per day; Reference category: 0–10 cigarettes) and (2) a higher frequency of current vaping (OR=1.97, 95% CI [1.36, 2.85] for 30+ cigarettes). Intention to quit was associated with a higher frequency of current vaping (OR = 1.48, 95% CI [1.21, 1.82]). Among those who reported ever vaped, higher baseline vaping frequency (OR=11.98, 95% CI [6.00, 23.93] for daily vaping at baseline; reference category: Vaped less than monthly) predicted current vaping.
Conclusion: Among daily smokers, amount smoked and intention to quit smoking appear to predict subsequent vaping uptake. Vaping frequency at baseline appears to predict current vaping at follow up.
