E-cigs At Least 96% Less Harmful
Compared to combustible cigarettes, e-vapor products are at least 96% less harmful and may substantially reduce individual risk and population harm
In this article from BMC Medicine, the author looks at recent studies on the effects of vapor products on lung function and concludes that switching to e-cigarettes from combustible tobacco could improve lung functions.
Although large longitudinal studies are warranted to elucidate whether ECs (e-cigarettes) are a less harmful alternative to tobacco cigarettes and whether significant health benefits can be expected in smokers who switch from tobacco to ECs, the emerging evidence that EC use can reverse harm from tobacco smoking should be taken into consideration by regulatory authorities.
