E-cigarettes help Brits to quit

The study, led by UCL researchers and funded by Cancer Research UK, found that as use of e-cigarettes in quit attempts went up from 2011 onwards, so did the success rate of quitting. And, when the increase in use of e-cigarettes flattened off somewhat around 2015, so did the increase in quit success. This led the team to estimate that in 2017 around 50,700 to 69,930 smokers had stopped who would otherwise have carried on smoking.

This study used data from the Smoking Toolkit Study, a series of monthly cross-sectional household surveys of individuals aged 16 and older in England going back to 2006. Data were based on approximately 1,200 past-year smokers each quarter (total n=50,498) between 2006 and 2017. Time series analysis assessed the association between current use of e-cigarettes and use of e-cigarettes during a quit attempt with quit attempts, overall quit rate, quit success rate and average cigarette consumption. Statistical adjustments were made for seasonality, underlying trends, population level policies, spending on tobacco mass media and the affordability of tobacco.
