South Korea announced it will regulate synthetic nicotine e-cigarettes under conventional tobacco laws starting April 24, closing a loophole that previously exempted these products from oversight. Under the revised Tobacco Business Act, synthetic nicotine is treated like traditional tobacco, banning its use in smoke-free zones with fines up to 100,000 won ($69), requiring sellers to register as authorized retailers, and prohibiting online sales. The law also targets youth-focused marketing, limiting flavor descriptors and packaging imagery, with violations carrying fines up to 5 million won ($3,472).
The Korea Disease Control and Prevention Agency reported a youth vaping rate of 2.9% in 2025, close to 3.3% for conventional cigarettes, with 61.4% of youth smokers using both. Health officials said the revision establishes a youth smoking prevention network aligned with WHO FCTC standards.
