In a study by the Lawrence Berkeley National Laboratory, researchers discovered two previously undiscovered, potential cancer-causing chemicals that can be found in the vapors of an e-cigarette. Those chemicals are Propylene Oxide and Glycidol. Both chemicals have been listed in the “probable carcinogen” category which includes red meat and fireplace smoke, but is just a step below “known human carcinogen.” Regardless of whether or not you believe that these two chemicals are carcinogens, the Centers for Disease Control (CDC) does suggest that any exposure to these chemicals can cause irritation of the skin, eyes, and respiratory system, to name a few.

Previous studies have shown that e-cigarettes release other harmful chemicals such as diethylene glycol, an ingredient in antifreeze, and formaldehyde. Altogether, the researchers found 31 harmful chemicals in the e-cigarettes they studied.

The study looked at e-cigarettes with two different types of heating coils, which creates the vapors for the user to inhale. They found that devices that only had one heating coil were linked to an increase of chemicals that were released, as compared to those with a double coil. Researchers also found that stronger voltage for the battery, meant hotter coils, which meant more chemicals being released. How long an e-cigarette has been used will also determine how much harmful chemicals are being emitted, with longer used devices increasing in chemicals released.
