Vapour from electronic cigarettes contains two previously undiscovered cancer-causing chemicals, according to a new study. Researchers at the Lawrence Berkeley National Laboratory found propylene glycol, an eye and respiratory irritant, and glycerin, a skin, eye and respiratory irritant, among 29 other chemicals released in e-cigarette vapour. E-cigs with one heating coil instead of two released higher amounts of chemicals because the coil was hotter, the study found. The higher the temperature inside the vaporizer’s heating coil, the more chemicals were emitted. Decomposition of those chemicals, caused by heating them inside an e-cig, also releases toxic chemicals such as acrolein and formaldehyde, according to the study published in the journal Environmental Science and Technology.
