Most attempts at smoking cessation result in relapse, and smokers generally make multiple quit attempts before succeeding.
Qualitative research suggests e-cigarettes can meet many of the needs of ex-smokers by substituting physical, psychological, social, cultural and identity-related aspects of tobacco addiction.
According to a time-series analysis of data from the Smoking Toolkit study, in which repeated cross-sectional surveys are conducted with a representative sample of households in England, increasing prevalence of e-cigarette use in current smokers was predictive of higher success rates of quit attempts.
Most participants were self-reported long-term abstinent smokers (86.3%).
Those who start on a low self-reported nicotine e-liquid concentration (strength) will be more likely to relapse to tobacco smoking than those starting on a higher nicotine e-liquid, after controlling for cigarettes per day (CPD) before cessation.
Results suggest a change in flavour choices over the course of vaping initiation and uptake. There was a reduction in the proportion of people using a tobacco flavour, and increase in the proportion using a fruit/sweet/food flavour, from initial to current flavour choice
According to the 2017 ASH-A survey, among current users, fruit flavours were the most popular.
