“Researchers regularly assess the scientific evidence on whether e-cigarettes can help people stop smoking. Regularly updated evidence across more than a hundred studies continues to show that nicotine vapes can help people who use cigarettes to quit smoking.”

“Researchers don’t yet know whether or how adding flavors to vapes might affect smoking and vaping. While fruity and sweet flavors can be appealing to people who smoke, tobacco and menthol flavors are sometimes more popular among older people who have a history of smoking tobacco.”

“Even more concerning is that in addition to the total nicotine content being high, they have a very high proportion of freebase nicotine, which facilitates faster delivery into the bloodstream. This makes them even more effective in delivering higher levels of nicotine compared to cigarettes.” — Nargiz Travis, MScPH (CAsToR Project Director, Georgetown University)

“A lot of the challenge in regulating in this space is recognising you have a reduced-risk product, but not a risk-free product. So how do we make sure it’s helping the people it can help, and isn’t harming the people who wouldn’t have otherwise used tobacco or nicotine?” — Jamie Hartmann-Boyce, DPhil (Assistant Professor, University of Massachusetts - Amherst and Co-Lead, CAsToR Policy Analysis and Dissemination (PAD) Core)
