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

Japan Tobacco International (JTI) is expanding its Ploom heated product ecosystem with LYO tobacco-free nicotine sticks. Designed specifically for Ploom devices, LYO contains nicotine but no tobacco. Public information shows that the product has gradually entered several European markets, including Spain, Portugal and Germany, and was officially introduced in Romania in July 2026. The launch highlights JTI’s efforts to explore broader nicotine consumable formats beyond traditional tobacco-based sticks.

South Korean lawmaker Jeong Jin-wook has again called for stronger government action against liquid synthetic nicotine vape manufacturers and sellers, alleging that some businesses may have avoided regulation through product labeling changes and corporate restructuring. According to Newsworks, JNILBO and other Korean reports, Jeong has held his third press conference on the issue, calling for a government-wide investigation. The dispute involves whether synthetic nicotine products should fall under tobacco regulations, tax implications and supply-chain transparency. South Korean government agencies have previously said some estimates of potential tax losses cannot be verified due to limited sales data.

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.

The U.S. Food and Drug Administration authorized 11 ZYN ULTRA nicotine pouch products made by Swedish Match USA through the premarket tobacco product application pathway on August 21, 2026. Ten of the authorized products have a labeled nicotine content of 9 mg, while ZYN ULTRA Smooth was authorized at 11 mg. The reviews were conducted through FDA’s nicotine pouch PMTA pilot program. FDA has now authorized 43 nicotine pouch products, including 23 through the pilot.

The U.S. Court of Appeals for the Ninth Circuit upheld the FDA’s denial of MH Global LLC’s applications to market flavored electronic nicotine delivery systems (ENDS). The court ruled that FDA’s comparative-efficacy framework, which requires applicants to show that flavored products provide greater cessation or switching benefits than tobacco-flavored alternatives, is consistent with the Tobacco Control Act’s “appropriate for the protection of the public health” standard. The court also found that FDA was not required to establish the framework through notice-and-comment rulemaking.

Cochrane’s 2026 update of its living review on electronic cigarettes for smoking cessation included 80 randomized controlled trials involving 29,861 adult smokers, with nine trials added in this update. The review retained its high-certainty conclusion that nicotine e-cigarettes increase smoking cessation rates compared with nicotine replacement therapy. In absolute terms, about 10 in 100 people using nicotine e-cigarettes may quit smoking for at least six months, compared with about 6 in 100 using NRT. The review found no clear difference in serious adverse event rates between the two groups, while longer-term safety and the relative effectiveness of newer device types remain less certain.
