Tobacco Consumption and Toxicant Exposure of Cigarette Smokers Using Electronic Cigarettes.
Nicotine Tob Res. First published online: December 21, 2016.
This study extends current literature by measuring change in smoking dependence and disease-associated biomarkers, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and a panel of eight common volatile organic compounds (VOCs) that are toxic tobacco smoke constituents in smokers who switch to electronic cigarettes. The findings support the idea of harm reduction, however some levels of toxicant exposure are still of clinical concern, particularly for dual users. Extrapolation of these results must be careful to separate the different toxic exposure results for exclusive switchers versus dual cigarette+EC users, and not to equate harm reduction with the idea that using ECs is harmless.
