Heating Coil Linked To Serious Vaping Injuries, Animal Study Suggests by Erik Lane | Oct 12, 2020 | DJ Blogs, Erik | 0 comments E-cigarettes are dangerous for a few reasons, but a new study finds the type of heating coil used in the device and the amount of voltage sent through it could be contributing to vaping-related lung injuries. University of California researchers found that lab rats suffered lung injuries when exposed to vapor from devices using high-powered heating coils made of nickel-chromium alloy, an effect not seen when stainless steel heating coils were used. Study leader Michael Kleinman says coils containing nickel and chromium are typically found in e-cigarette devices, and it’s possible that these coils cause more damage to the lungs because the high voltage and the primary components of the e-liquid combine to create a toxic chemical reaction, among other possibilities.
