Use of e-cigarettes may help between 50,000 and 70,000 smokers in England quit every year, new research has shown.
Researchers from University College London (UCL) assessed the correlation between the use of e-cigarettes and success rate of quitting smoking.
The study, published in scientific journal Addiction, used data from the Smoking Toolkit, a series of monthly surveys of households in England aged 16 and above that date back to 2006.

According to the study, funded by Cancer Research UK, the success rate of smokers quitting tobacco cigarettes increased from 2011 as the number of smokers using e-cigarettes increased.
The number of smokers using e-cigarettes to quit levelled out around four years ago, as did the success rate of quitting.
By assessing 50,598 smokers between 2006 and 2017, the researchers concluded that in 2017, between 50,700 and 69,930 smokers quit who would have likely continued had they not started vaping.
The scientists investigated the connection between smokers’ current use of e-cigarettes and their use of e-cigarettes while attempting to quit, in addition to their number of quit attempts.
The team also assessed the participants’ quitting success rate and the quantity of cigarettes they would typically smoke. The researchers took several potentially influential factors into account, including the affordability of tobacco cigarettes and seasonality.

Dr Emma Beard, senior research associate at UCL and lead author of the study, explained the study is further evidence that vaping can help smokers to quit.
“This study builds on population surveys and clinical trials that find e-cigarettes can help smokers to stop,” Dr Beard said. “England seems to have found a sensible balance between regulation and promotion of e-cigarettes.” Dr Beard added that marketing of e-cigarettes is “tightly controlled”, so very few people who have never smoked are using e-cigarettes. “Millions of smokers are using them to try to stop smoking or to cut down the amount they smoke.”
