Electronic cigarettes (e-cigarettes) are gaining popularity in the United States, exacerbating concerns regarding limited research on these products’ safety. In order to understand the chemistry of e-cigarettes, a detailed chemical evaluation of their design and chemical composition, including the aerosol generated with use, is necessary. This study will collect and evaluate the chemical composition of e-cigarette liquids and aerosol. Researchers will test approximately 20 e-cigarette product lines from nine different brands to qualitatively screen for constituents present in the e-liquid and the vapor. Data collected from this study may inform the science base needed to effectively evaluate and regulate e-cigarettes.
