“There’s a common belief that electronic cigarettes pose less cancer risk because e-cigarettes do not produce tar. But I am not convinced; there have been no long-term studies. E-cigarettes have also been promoted as a way to quit smoking tobacco, but there is no proof they work better than just quitting outright or using FDA-approved aids. And on the flip side, there’s an emerging concern that teens and young adults who vape are more likely to become cigarette smokers.” — Kathy Albain, oncologist at Loyola Medicine
