And results seem to lean in this direction. A study was published in BMJ in July 2017, and followed 100.000 Americans. This study actually confirms a growing increase of e-cigarette use linked with decreasing tobacco use figures.
Similar results were reached in another study which was published in the Nicotine & Tobacco review in August 2017. According to this study, there’s a clear link between e-cigarette use and a high success rate of tobacco use cessation.
These different results show a significant impact of the e-cigarette on tobacco use reduction. But some doubts remain regarding this cause and effect relationship. Indeed, studies conducted until now do not distinguish punctual e-cig users from regular e-cig users.
Frequency of use is a key success factor
The last study we will focus on was published in Nicotine & Tobacco. It was led by Professor David T. Levy and his team from Georgetown University. He analyzes further the reasons for the failure of tobacco cessation despite using e-cigarettes
. The data shows that the frequency of use is a key success factor in succeeding to stop tobacco use. Actually, if those who vape quite seldom have a high failure rate in tobacco cessation, those who vape several times a day and for several months have higher chances to succeed.
Future studies should enable to confirm this link between e-cigarette and tobacco cessation, but it’s important to closely monitor the frequency of use of vaping.
