Louisville University receives funding for e-cigarette research
University of Louisville receives $3.6 million for research on harmful chemicals in e-cigarettes, testing flavors on mice and cells.

The University of Louisville has received a total of $3.6 million in funding from the U.S. Food and Drug Administration (FDA) and National Institutes of Health (NIH) for research into potentially harmful chemicals found in electronic cigarettes.

 

Researchers will be creating electronic cigarette products with various flavors to determine potential short-term and long-term health effects.

 

Based on our current understanding, there is toxicity present in some flavors," said Alex Carll, co-leader of the project and associate professor at the University of Louisville.

 

Researchers aim to identify which chemicals have adverse effects on the body, particularly the heart, due to the plethora of flavors available on the market.

 

To determine the risks associated with various flavor combinations, researchers will test them on mice and monitor their heart rates, simulating the way people inhale electronic cigarettes.

 

Subsequently, researchers will test individual chemicals on myocardial cells.

 

Researcher will analyze data to determine the short-term and long-term health effects of certain chemicals over time.

 

Carll stated, "As a scientist, I may not be able to determine what is right or wrong, but I can at least inform the public about the toxicity of certain seasoning chemicals.

 

According to researchers involved, funding for this study will continue until 2027 and they have reported preliminary results.

Canada Health Minister Says She Is Not Considering Looser Nicotine Pouch Retail Rules as PMI-Linked Group Pushes for Wider Access
Canada Health Minister Says She Is Not Considering Looser Nicotine Pouch Retail Rules as PMI-Linked Group Pushes for Wider Access
Canadian Health Minister Marjorie Michel says she is not considering loosening retail restrictions on nicotine pouches. Canada regulates pouches containing 4 mg or less of nicotine per unit as non-prescription nicotine replacement therapy and requires newer NRT formats such as pouches to be sold from behind pharmacy counters. Meanwhile, Unsmoke Canada, linked to Philip Morris International's Canadian business, is pushing to allow pouches in convenience stores and other general retail outlets. Health Canada also acknowledges continued unauthorized sales, while recent research shows rising pouch use among Canadian youth aged 16 to 19.

China Tobacco Yunnan files patent for cellulose-free nicotine pouch scaffold to replace microcrystalline cellulose
China Tobacco Yunnan Industrial Co., Ltd. has filed a patent application for a cellulose-free scaffold material for nicotine pouches, proposing a combination of bioceramic material, polydextrose and sugar alcohols to replace conventional microcrystalline cellulose and cellulose derivatives. The filing aims to address issues including powdery mouthfeel, residue and limited release control, while also reducing reliance on existing cellulose-based patent portfolios. In patent examples, one fast-release formulation reached a nicotine release rate of 50% at 10 minutes and more than 90% at 20 minutes.

UK HMRC Launches Vape Duty Stamps on October 1, Ushering in Supply-Chain Traceability as Chinese Exporters Face New Compliance Hurdles
UK HMRC Launches Vape Duty Stamps on October 1, Ushering in Supply-Chain Traceability as Chinese Exporters Face New Compliance Hurdles
HM Revenue & Customs put the UK's Vaping Products Duty and Vaping Duty Stamps Scheme into effect on October 1. All vaping liquids manufactured in or imported into the UK are now subject to duty at £2.20 per 10ml, regardless of nicotine content. The stamp regime will introduce digital functionality designed to provide traceability throughout the supply chain, with approved manufacturers, importers and warehousekeepers required to report product movements and retailers and consumers eventually able to scan stamps to verify authenticity. China exported $177 million of vape-related products to the UK in August, up 51.4% year over year, increasing the significance of the new compliance regime for China's Shenzhen-centered vape supply chain.

NAS 2026 | Former FDA Tobacco Chief Mitch Zeller Calls for Shift From “End Game” to “End State”
At the 2026 New Approaches Summit in New York, former FDA Center for Tobacco Products Director Mitch Zeller called for the tobacco harm reduction debate to shift from the traditional “end game” toward defining a desired “end state.” He also highlighted unresolved concerns around dual use, argued that biomarkers of exposure may be more meaningful than cigarettes-per-day in assessing risk reduction, and said nicotine misperceptions remain a major barrier to public health progress.
