Yes. There is a rapidly growing body of evidence suggesting vaping is an effective means to give up cigarettes.
A study published earlier this year in the New England Journal of Medicine found “e-cigarettes were more effective than nicotine-replacement therapy,” while another study in the Harm Reduction Journal published in 2018 found “vaping is a viable long-term substitute for smoking.”
In fact, a 2018 report by Public Health England found quit smoking success rates in 2017 were at their highest observed level. The evidence suggests that e-cigarettes have contributed to tens of thousands of additional quitters in England.
Another Greek study found the biggest indicator for someone being a former smoker is whether they are a daily user of vapes. A different study again found those who use e-cigarettes every day were more likely to quit smoking (or at least, smoke less) when compared with those who do not vape.
As a quit tool, evidence suggests vaping is the most effective. It is absurd to deny smokers access to a far more effective quit tool and less harmful alternative smoking.
