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).

Reynolds Puts Nearly 183,000 U.S. Contracted Outlets Under Age-Verification Rules, Covering 94% of Volume — Can It Shift an Unauthorized Vape Market?
Reynolds Puts Nearly 183,000 U.S. Contracted Outlets Under Age-Verification Rules, Covering 94% of Volume — Can It Shift an Unauthorized Vape Market?
Reynolds American says nearly 183,000 U.S. retail outlets are under contract, with its Retail Marketing Plan Contract covering about 94% of company volume and requiring point-of-sale age verification. The company combines those contracts with We Card, TruAge, NACS-linked infrastructure and POS integration, while enhanced Vuse Pro retail rules add ID scanning, purchase limits and stronger underage-sales accountability. The initial Vuse Pro rollout targets about 50,000 stores. The system is taking shape as unauthorized vapor products remain dominant in parts of the U.S. market: a 2026 study estimated they accounted for 69.4% of tracked brick-and-mortar e-cigarette dollar sales in December 2025.

JUUL Purchasers Ask Ninth Circuit to Preserve Antitrust Classes in Case Over Altria’s $12.8 Billion Investment
JUUL Purchasers Ask Ninth Circuit to Preserve Antitrust Classes in Case Over Altria’s $12.8 Billion Investment
Private antitrust litigation stemming from Altria's 2018 $12.8 billion investment for a 35% economic interest in JUUL is advancing before the U.S. Court of Appeals for the Ninth Circuit. Direct purchasers, indirect purchasers and indirect resellers of JUUL products filed answering briefs this week seeking to preserve class certifications granted by a California federal court in February. Altria and JUUL argue that individual consumers and large distributors differ too much in purchasing terms to remain in a single direct-purchaser class, while a separate dispute concerns whether California antitrust law can apply to indirect purchasers across 27 jurisdictions. A September trial has been put on hold during the appeal.

NATO Executive Director David Spross Sees U.S. Vape Regulation Improving, Calls for More PMTA Authorizations and Warns of 2027 State Tax Pressure
The National Association of Tobacco Outlets is calling for more FDA marketing authorizations, greater transparency in the PMTA process and continued enforcement against unauthorized e-cigarettes, even as its executive director, David Spross, points to recent regulatory developments as signs of progress. At the state level, excise taxes, flavor restrictions and vapor product directories remain major issues for tobacco retailers. By August 2026, 17 states had enacted laws establishing state-managed e-cigarette directories or similar systems.
