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.

UK PM Andy Burnham Reshapes Vape Retail Rules as Licensing Could Raise Barriers for New Shops
UK Prime Minister Andy Burnham is pushing a high street reform agenda that could give local authorities greater powers over commercial activity, including vape retail. The reforms could involve expanded planning powers and a potential vape retail licensing system, allowing councils to play a larger role in store locations and market access. The measures are part of the UK’s broader shift toward tighter vape regulation, although no nationwide vape retail restrictions have yet been implemented.

China Tobacco Hubei explores staged nicotine pouch delivery, using dynamic membranes to slow early release and gradient particles to sustain later delivery
China Tobacco Hubei explores staged nicotine pouch delivery, using dynamic membranes to slow early release and gradient particles to sustain later delivery
China Tobacco Hubei Industrial Co., Ltd. disclosed several oral nicotine-related patent applications in August 2026, including two that approach staged nicotine release from different directions. One uses a high-viscosity membrane that forms inside the pouch after contact with saliva to slow rapid early release, while the other uses gradient particles with a faster-disintegrating outer layer and a slower core to create a fast-to-sustained release profile. Together, the filings explore how nicotine pouches could balance initial delivery with release later in use.
