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.

PMI Global Communications Chief Moira Gilchrist: Why AI Matters More Than Ever in the Smoke-Free Transition
Philip Morris International (PMI) Chief Global Communications Officer Moira Gilchrist said artificial intelligence is changing how companies understand audiences, manage owned information channels and communicate business transformation. PMI is using AI-generated audience personas to test messaging while optimizing its corporate website and other owned channels for large language models. As PMI continues its transition from cigarettes toward smoke-free products, Gilchrist said owned data and corporate channels are becoming increasingly important in demonstrating the scale of that transformation.

Wall Street Journal: U.S. FDA Plans Faster Vape and Nicotine Pouch Reviews, Revisit of 2021 PMTA Rule
The Trump administration is preparing changes intended to accelerate FDA market authorization reviews for e-cigarettes and nicotine pouches, according to The Wall Street Journal. The FDA is expected to revisit its 2021 PMTA rule and may simplify some scientific study requirements and shorten review times. The agency has not formally announced the changes. Over the past year, the FDA has already accelerated nicotine-pouch reviews, expanded ENDS authorizations and upgraded its CTP Portal NextGen application system. As of August 2026, 43 nicotine pouch products and 48 e-cigarette products had received FDA marketing authorization.

From Nicotine Salts to Cocrystals: China’s Shenzhen Huabao institute explores a more stable form for sustained nicotine release
From Nicotine Salts to Cocrystals: China’s Shenzhen Huabao institute explores a more stable form for sustained nicotine release
China-based Shenzhen Huabao Collaborative Innovation Technology Research Institute Co., Ltd. has filed a patent application for a nicotine-ascorbic acid cocrystal, exploring a new solid-state form of nicotine. The patent proposes applications across e-liquids, heated tobacco sticks, oral tobacco, chewing tobacco and snuff. In nicotine pouch tests disclosed in the filing, cocrystal formulations showed less than a 6% decline in nicotine content after three months of accelerated storage and a release profile combining early-stage release with sustained delivery over 60 minutes. The filing reflects exploration of nicotine forms beyond conventional nicotine base and nicotine salts.
