Liquid-based e-cigarettes emit 12 times more ultrafine dust than regular cigarettes, according to a recent study by the Korea Disease Control and Prevention Agency.

Liquid-based e-cigarettes emit 12 times more ultrafine dust than regular cigarettes: study

By photographing smoke and aerosols emitted from cigarettes to analyze their chemical composition, the results showed that liquid-based e-cigarettes emitted 172,845 micrograms (㎍) of ultrafine dust per 0.2 grams of liquid, 12 times more than what was emitted by non-electronic cigarettes.

 

Meanwhile, heated e-cigarettes emitted 3,100 ㎍ of ultrafine dust per cigarette, lower than emissions from non-electronic cigarettes.

 

Over a three-minute period, the ultrafine dust emitted by liquid-based e-cigarettes spread as far as 10 meters, heated e-cigarettes to between 6 and 7 meters and non-electronic cigarettes to 3 meters.

 

The study also revealed that black carbon, a chemical related to the automobile emissions stains, is released by all three types of cigarettes.

 

The highest black carbon levels were from non-electronic cigarettes, which were also present in liquid-based e-cigarettes (98.8 ㎍ per piece) and heated e-cigarettes (11.41 ㎍ per piece).

Canada Health Minister Says She Is Not Considering Looser Nicotine Pouch Retail Rules as PMI-Linked Group Pushes for Wider Access
Canada Health Minister Says She Is Not Considering Looser Nicotine Pouch Retail Rules as PMI-Linked Group Pushes for Wider Access
Canadian Health Minister Marjorie Michel says she is not considering loosening retail restrictions on nicotine pouches. Canada regulates pouches containing 4 mg or less of nicotine per unit as non-prescription nicotine replacement therapy and requires newer NRT formats such as pouches to be sold from behind pharmacy counters. Meanwhile, Unsmoke Canada, linked to Philip Morris International's Canadian business, is pushing to allow pouches in convenience stores and other general retail outlets. Health Canada also acknowledges continued unauthorized sales, while recent research shows rising pouch use among Canadian youth aged 16 to 19.

JTI Research Finds 31% of UK Respondents Offered Illicit Tobacco, While 63% of Ennis Packs Lack Duty Marks
JTI Research Finds 31% of UK Respondents Offered Illicit Tobacco, While 63% of Ennis Packs Lack Duty Marks
Multiple JTI-backed studies in the UK and Ireland indicate that illicit tobacco remains visible across consumer interactions and local markets. In the UK, JTI research found that 31% of respondents said they had been offered illicit tobacco products. In Ireland’s Ennis area, a JTI-commissioned empty pack survey found that 63% of sampled cigarette packs did not carry Irish duty-paid markings. The findings come from industry research rather than official government estimates of illicit tobacco market size, but highlight continued concerns among regulators, legitimate retailers and tobacco companies over illicit trade.

Malaysia’s Vape Rules Face Review as Health Minister Dzulkefly Ahmad Addresses Dropped Nicotine Appeal
According to Free Malaysia Today on August 26, 2026, Malaysia’s Health Minister Dzulkefly Ahmad said the Health Ministry would explain the government’s decision to withdraw its appeal against a High Court ruling involving the exemption of liquid nicotine used in vape products from the Poisons List. The High Court previously ruled that the exemption decision was irrational. Dzulkefly said withdrawing the appeal did not mean the government would stop regulating vaping, and that future regulatory approaches would continue under existing legal frameworks.

Special Report | Can Nicotine Be Replaced? 6-MN Is Already on the Market While Key Human Evidence Is Still Missing
Special Report | Can Nicotine Be Replaced? 6-MN Is Already on the Market While Key Human Evidence Is Still Missing
Nicotine analogues such as 6-methylnicotine are already appearing in e-cigarettes and oral pouches, even as key human evidence remains limited. A new Nixodine-S study adds nonclinical data showing differences from nicotine in cytotoxicity and receptor activity, while independent studies point to a more complex toxicological picture. With supply-chain activity growing and FDA seeking clearer authority over nicotine analogues, the industry now faces a larger question: what evidence is needed before these substances can credibly replace nicotine?
