South Korea to Tighten Vape Regulation in 2026

South Korea will classify synthetic nicotine e-cigarettes as tobacco under the revised Tobacco Business Act, which takes effect on April 24, 2026, marking the first change to the legal definition of tobacco since 1988. The amendment closes a regulatory loophole that previously excluded synthetic nicotine products and brings them under the existing tobacco control framework. Earlier government research found that such products contain carcinogens and other harmful substances.

 

Under the new framework, synthetic nicotine e-cigarettes must carry mandatory pictorial and text health warnings on their packaging. Advertising rules will also become stricter, and use will be banned in smoke-free areas such as schools, hospitals, and government buildings. Flavor marketing aimed at young people will be prohibited, and online sales, social media promotion, outdoor displays, and sponsorship activities will also be banned. Sales of e-cigarettes will be limited to designated tobacco retail stores.

 

Other measures include tighter controls on vending machines, requiring adult verification systems, and a ban on the use of vending machines in education protection zones starting in February 2026. Health authorities said they have prepared a compliance monitoring manual for manufacturers and importers.
