The data for this study were collected from the 2014/15 Tobacco Use Supplement-Current Population Survey (TUS-CPS) on cigarette and e-cigarette use, and individual characteristics were supplemented with information on state tobacco control policies. The study authors estimated quit attempts amongst those who had smoked a year earlier and remained abstinent for at least 3 months amongst those making a quit attempt.
The results indicated that e-cigarette users were more likely to have tried to quit smoking than non-users. Amongst those making at least one quit attempt, quit success was lower amongst never users, but higher amongst those who had used e-cigarettes at least 5 times in the last month. “Both quit attempts and quit success were linearly related to the frequency of e-cigarette use,” read the study abstract.
A UK study indicating the success rate of smoking cessation via vaping
“After 90 days, the complete abstinence rate was 36.5% from 0% at baseline. Frequency of daily smoking reduced from 88.7% to 17.5% (P<0.001) and median consumption of cigarettes/day from 15 to 5 (P<0.001),” reported the authors of the UK study.
On the basis of this data the study authors had concluded that it may be beneficial for smokers to be provided with e-cigarettes at zero or minimal costs for at least a short period, by smoking cessation services or any health providers who may be assisting them to quit.
