E-Cigs Can Damage DNA, Increase Cancer Risk
Using electronic cigarettes can damage the DNA in users’ oral cells, which could increase their cancer risk, finds a new study. The findings of the study were presented at the 256th National Meeting & Exposition of the American Chemical Society.
Researchers collected saliva samples from people before and after 15 minutes of vaping. They found three DNA-damaging compounds, including formaldehyde in the users’ saliva.
The damage was mostly found to be related to acrolein exposure, which is produced when glycerol is heated. Glycerol is found in propylene glycol and vegetable glycerin, which are some of the main ingredients in e-liquid.
