Background: While some smokers use e-cigarettes and stop smoking, a substantial proportion try e-cigarettes and later discontinue or use them concurrently with smoking (current dual users). The aim was to assess factors associated with ongoing e-cigarette use and discontinuation among smokers. Methods: Secondary analysis of data of 1489 currently smoking adults, 18 and above, from a GB population-based online survey conducted in March 2016. A multivariable logistic regression assessed motivation to stop smoking among never e-cigarette users, past triers (= weekly use), and current dual users. A multinomial logistic regression assessed associations of e-cigarette use status with motivation to stop smoking, reasons for use, age, gender, social grade, heaviness of smoking, and type of first e-cigarette used. Reasons for discontinuing use were assessed. Results: Current dual users were more motivated to stop smoking than past users (AOR = 1.95, 95% CI: 1.10-3.46); never users' or past triers' motivation did not differ from past users'. Dual users were less dependent on cigarettes (AOR = 0.54, 95% CI: 0.35-0.86) and more likely to use e-cigarettes as an aid to reduce smoking (AOR = 2.40, 95% CI: 1.59-3.64) and to deal with smoking restrictions (AOR, 2.03, 95% CI: 1.22-3.38) than past users. Smokers mostly discontinued e-cigarettes because they did not feel like smoking, did not help with cravings, or respondents had just wanted to try them. Conclusion: Among smokers, ongoing use of e-cigarettes is associated with reasons for reducing smoking and dealing with smoking restrictions, heightened motivation to stop smoking, and lower dependence on smoking.
