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.

New Zealand Associate Health Minister Casey Costello Warns on Illicit Cigarettes as Legal Tobacco Sales Halve Over Decade
New Zealand Associate Health Minister Casey Costello said legal tobacco sales in the country have fallen by more than half over the past decade, with sales declining more than 20% in 2025 compared with the previous year. She warned that the decline may not fully reflect lower smoking rates, as increased availability of illicit cigarettes could also be contributing. The government said it would continue strengthening tobacco and vape retail enforcement while monitoring the impact of illicit tobacco on public health and tax revenue.

NATO Executive Director David Spross Sees U.S. Vape Regulation Improving, Calls for More PMTA Authorizations and Warns of 2027 State Tax Pressure
The National Association of Tobacco Outlets is calling for more FDA marketing authorizations, greater transparency in the PMTA process and continued enforcement against unauthorized e-cigarettes, even as its executive director, David Spross, points to recent regulatory developments as signs of progress. At the state level, excise taxes, flavor restrictions and vapor product directories remain major issues for tobacco retailers. By August 2026, 17 states had enacted laws establishing state-managed e-cigarette directories or similar systems.
