*This study, although conducted under very high exposure conditions in a small, non-ventilated vape shop with many employees and customers vaping and clouds of vapor visible, did not document any dangerous levels of exposure to any hazardous chemical. Nicotine exposure was essentially non-existent. *Formaldehyde exposure was no different than in many indoor and outdoor environments at baseline. Acetone, acetoin, other aldehydes, toluene, benzene, and xylene were not detected. Chemicals that have been associated with "popcorn lung" were also not detected by the standard method. | *This study, although conducted under very high exposure conditions in a small, non-ventilated vape shop with many employees and customers vaping and clouds of vapor visible, did not document any dangerous levels of exposure to any hazardous chemical.

*Tobacco cigarette smoke provided the samples containing highest concentrations of all compounds analyzed. Besides nicotine it contained benzene, toluene, xylenes, ethylbenzene and naphthalene in high abundance as well as other compounds such as isoprene, pent-1-ene, n-pentane, n-hexane, n-heptane and others. | |||
*This composition was in strong contrast with that of vapor from the e-cigarettes in which all these compounds were virtually absent except nicotine | |||
