Brief Summary

Electronic or e-cigarettes are battery-powered devices that deliver vapor which may be inhaled in the manner tobacco is smoked. The e-liquid is usually a solution containing propylene glycol and/or vegetable glycerin, nicotine, and flavor concentrates, although some e-liquids also are sold as non-nicotine containing products. The long- and short-term public health consequences of e-cigarette use, including the effects of e-cigarettes on tobacco use behavior, are not well understood. However, the prevalence of e-cigarette use appears to be undergoing a rapid increase.

In this study the investigators propose to analyze nicotine pharmacokinetic in blood and to compare the exhaled breath before and after e-cigarette smoking. They want to obtain a pharmacokinetic model of this population for nicotine. And they want to identify if molecules contained in vapor are absorbed, metabolized or modified by the organism.
