Study finds reduced toxicity of ENDS compared to cigarettes.
Researchers validated reliability of results. Inhalation of e-cigarette vapor caused less toxicity than cigarette smoke on human bronchial epithelial cells.

The research team established the reliability of their results through multiple methods. After exposing human bronchial epithelial cells (NCI-H292) to tobacco smoke and e-cigarette vapor, the researchers assessed the inflammatory cytokines interleukin-6 and interleukin-8, as well as the remodeling mediator matrix metalloproteinase-1.


Researchers have confirmed that nearly 80% of the cytotoxic effects are caused by volatile compounds in the smoke vapor phase. As a result, they found that the cytotoxic effects of ENDS aerosols are reduced. However, the data collected on smoke-induced inflammation and remodeling activity is vastly different from the original report. Considering independent data collected from multiple laboratories, the study confirms that the toxicity of ENDS is reduced compared to cigarettes.
