E-cigarettes have become vastly popular among current and new smokers. They have been marketed as a healthier alternative to traditional cigarettes. There are many models that allow consumers to customize different aspects in the vaping process, such as flavors and nicotine concentration in e-liquid and, in some models, the power/temperature setting used to vaporize the e-liquid. These have a lesser known health hazard from the presence of carbon monoxide (CO) in the e-cigarette effluent. This project utilizes diode laser spectroscopy to quantify the CO concentration present in the effluent among various power settings and flavoring agents. The preliminary tests show that higher power settings yield higher CO concentrations and there are some variations among flavors which need to be further explored. The observed CO production under these vaping conditions along with an understanding of the chemical reactions that occur during the vaporization process could inform the public as well as regulators about the possible health effects of e-cigarettes.
