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.

South Korea Extends Vape Rules to Unmanned Stores After Bringing Synthetic Nicotine Under Tobacco Law
South Korea Extends Vape Rules to Unmanned Stores After Bringing Synthetic Nicotine Under Tobacco Law
South Korea's Ministry of Gender Equality and Family said on September 14 that it plans to designate unmanned e-cigarette stores as businesses where minors are prohibited from entering or working. Operators would be required to verify customers' ages and display notices restricting access by minors. The proposal is open for public comment through October 6. The move follows an April expansion of South Korea's statutory tobacco definition that brought products made with natural or synthetic nicotine under the Tobacco Business Act. Nicotine-free liquids and products using nicotine analogues such as 6-methylnicotine, however, remain an emerging regulatory issue.
