South Korea Extends Vape Rules to Unmanned Stores After Bringing Synthetic Nicotine Under Tobacco Law
South Korea Extends Vape Rules to Unmanned Stores After Bringing Synthetic Nicotine Under Tobacco Law
South Korea's Ministry of Gender Equality and Family said on September 14 that it plans to designate unmanned e-cigarette stores as businesses where minors are prohibited from entering or working. Operators would be required to verify customers' ages and display notices restricting access by minors. The proposal is open for public comment through October 6. The move follows an April expansion of South Korea's statutory tobacco definition that brought products made with natural or synthetic nicotine under the Tobacco Business Act. Nicotine-free liquids and products using nicotine analogues such as 6-methylnicotine, however, remain an emerging regulatory issue.

Cochrane 2026 Update Adds Nine Trials, Keeps High-Certainty Finding That Nicotine E-Cigarettes Improve Quit Rates Over NRT
Cochrane 2026 Update Adds Nine Trials, Keeps High-Certainty Finding That Nicotine E-Cigarettes Improve Quit Rates Over NRT
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.
