According to a report from the Montreal Chest Institute, e-cigarettes helped so called “hardcore smokers” quit smoking and stay off of cigarettes for up to a year later. Forty-three percent of smokers who tried to quit by switching to vaping were still off of cigarettes three months to a year later, according to the results, which tracked smokers a year after switching.

In the study, 32 out of 75 smokers that switched to e-cigarettes quit for good, according to the results. 

“It really is encouraging as a jumping off point to really look at this long term with the clients that we follow,” said Siobhan Carney, a nurse practitioner with the project.
