Cardiovascular effects of electronic cigarettes

The available literature suggests that electronic cigarettes (e-cigarettes), although not without risk, might decrease cardiovascular risk in long-term smokers of tobacco cigarettes who switch to e-cigarettes. However, to safeguard our youth, e-cigarettes must be required to meet product standards, all flavourings must be banned and laws regulating e-cigarette sales must be strictly enforced.
