As e-cigarette use becomes more popular more questions are being raised about the safety of some e-cigarette ingredients. Researchers at the University of North Carolina Health Care developed a system for rapid evaluation of e-liquid toxicity in which human cells are exposed to different e-liquids. In general, the more ingredients in an e-cigarette, the greater the toxicity. Two commonly-used flavor compounds, vanillin and cinnamaldehyde are suspected of toxicity, depending on their concentrations. Researchers say there are more than seven thousand e-liquid products and their goal is making sure people know more about the ingredients. A database with that toxicity information is available at www.eliquidinfo.org.
