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

Wisconsin's electronic vaping device directory has been fully enforced for more than a year, and local vape retailers say the reduced range of eligible products has contributed to declining sales, store closures and layoffs. Johnny Vapes owner Ben Hall said he has closed four of seven locations and cut about 70% of his staff. State law bars the sale of vaping devices not listed on the Wisconsin Department of Revenue directory and allows penalties of $1,000 per day for each unlisted device sold or offered for sale. In April 2026, the U.S. Court of Appeals for the Seventh Circuit allowed enforcement of the law to continue.

Malaysia’s withdrawal of its appeal in a landmark liquid-nicotine case has left a High Court ruling that struck down the 2023 nicotine exemption in force, bringing liquid and gel nicotine used in vaping products back under the Poisons Act 1952. At the same time, the Control of Smoking Products for Public Health Act 2024 continues to provide a regulatory framework for vaping products, creating uncertainty over retail sales, taxation and existing inventory. MPs are calling for nicotine vape sales and excise collection to stop, including refunds of more than RM354 million collected since 2023, while industry and consumer groups are asking the government to clarify the current legal position.

Alimentation Couche-Tard said U.S. same-store sales in its “other nicotine products” category grew at a double-digit rate in the first quarter of fiscal 2027, led by nicotine pouches, while overall U.S. same-store merchandise revenues increased 1.7%. The company also said its Canadian nicotine business continued to face regulatory pressure and illicit-market headwinds. The U.S. performance coincides with Couche-Tard's participation in efforts to reopen Canadian convenience-store access to authorized nicotine pouches, though the company has not established a direct causal link between the two.

South Korea's Constitutional Court has upheld fixed taxes on nicotine-containing e-cigarette liquids based on solution volume, ruling that challenged provisions imposing KRW 370 per milliliter in individual consumption tax and KRW 628 per milliliter in tobacco consumption tax do not violate the Constitution. The cases stemmed from historical disputes involving importers that reported nicotine as being extracted from tobacco stems rather than leaves. South Korea has since broadened its tobacco definition to include synthetic nicotine, while current tax laws provide reduced rates for certain products not derived from tobacco.

Less than a week after JUUL2 received U.S. FDA marketing authorization on August 28, 2026, JUUL Labs was sued for patent infringement in federal court in Delaware. AJ Marketing LLC filed the complaint on September 3, alleging that both JUUL 1 and JUUL2 infringe U.S. Patent No. 8,851,068 B2. The patent covers aspects of programmable electronic vaporization devices, including controls over dose delivery, usage frequency and operating parameters. The plaintiff is seeking reasonable royalties and ongoing royalties tied to the remaining life of the patent. JUUL has not yet publicly responded to the case.

German prosecutors and customs authorities are conducting a criminal investigation into an alleged cross-border organised vape network. Authorities say that between January 2024 and March 2025, four employees of an unnamed Chinese e-cigarette manufacturer allegedly built a network of sales agents and wholesalers that brought more than 7.6 million nicotine disposable vapes into Germany, causing an estimated €33.3 million in excise-tax losses. The manufacturer has not been named. Some products visible in enforcement images have packaging resembling products from FUMOT’s portfolio. European regulatory records from 2024, FUMOT’s public overseas-sales materials and records involving German vape importer and distribution company Zamu-Pro GmbH also show FUMOT/RandM products and German distribution activity during the period covered by the investigation.
