Oral health: Vaping inflicts damage and can lead to ‘irreversible’ problems

The Zhengzhou Tobacco Research Institute of China National Tobacco Corporation has filed a patent application for an end-to-end method to analyze the migration and transformation of chemical compounds in heated tobacco products. Using GC-Orbitrap/MS non-targeted analysis, the method compares tobacco substrate and aerosol samples to distinguish compounds transferred directly from the substrate from those newly formed during heating, while also calculating transfer rates. In an example involving nine heated tobacco products, the patent identified 17 newly formed thermal decomposition compounds and 38 transferred compounds.

Australia's Therapeutic Goods Administration published a final decision on September 25 to classify 6-methylnicotine as a Schedule 9 prohibited substance under the Poisons Standard, effective October 1, 2026. TGA said the chemical has been reported in e-cigarette liquids sold in Australia and marketed as nicotine-free or nicotine alternatives, while evidence also indicates its use in preparations such as oral pouches. The government originally proposed a Schedule 7 classification but ultimately adopted the stricter Schedule 9 designation, citing acute toxicity, dependence risk, use in unapproved consumer products and misleading marketing.

Imperial Brands has agreed to acquire 100% of Swedish modern oral nicotine company Yoik Group AB for an initial SEK515 million, equivalent to about US$53.9 million, plus a deferred payment linked to performance over the next two years. Yoik owns nicotine pouch brand Helwit, which held about 3.4% of Sweden’s modern oral nicotine market over the past 12 months. Imperial says the acquisition will more than double its existing share of the Swedish market. Helwit is also sold elsewhere in the Nordics, through European online channels and in selected UK retail outlets.

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.

New York State will extend its tobacco products tax to “alternative nicotine products,” including tobacco-free nicotine pouches, from September 1, 2026, at a rate of 75% of the wholesale price. Distributors, wholesalers and retailers must also inventory products held as of 11:59 p.m. on August 31 and pay a floor tax. Vapor products are excluded from the new category and remain subject to New York's separate 20% supplemental sales tax on the retail price.

Philip Morris International (PMI) has launched ZYN Melts in the UK, introducing a fully dissolvable oral nicotine tablet format alongside the brand's existing nicotine pouches. The range includes Cool Mint and Peppermint, each offered at 1mg and 2mg of nicotine per tablet, creating four SKUs. Each can contains 20 tablets and is priced at £6.50 in the UK. Unlike ZYN nicotine pouches, Melts are placed between the upper lip and gum and dissolve completely during use.
