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.

Australia’s One Nation Proposes 75% Tobacco Tax Cut, Says Lower Prices Could Hit Illicit Market
Australia’s One Nation Proposes 75% Tobacco Tax Cut, Says Lower Prices Could Hit Illicit Market
Australia’s One Nation party has proposed cutting tobacco excise by 75%, arguing that lower legal cigarette prices could narrow the gap with illicit tobacco and reduce demand for black-market products. The proposal comes as Australia continues expanding enforcement against illicit tobacco supply chains through border controls, retail inspections and organised-crime investigations. Supporters argue high taxes have contributed to illicit-market growth, while opponents warn that lower tobacco prices could undermine public-health goals. The proposal is a party policy position and has not been adopted by the Australian government.
