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).

Imperial Brands has agreed to acquire 100% of Swedish modern oral nicotine company Yoik Group AB for an initial SEK515 million, equivalent to about US$53.9 million, plus a deferred payment linked to performance over the next two years.

Australia Brings in Deloitte to Support Illicit Tobacco and Vape Enforcement Across Data, Processes and Project Delivery
Australia’s Department of Home Affairs has hired Deloitte to provide data analytics, business-process, communications and project-delivery support to the Office of the Illicit Tobacco and E-Cigarette Commissioner. The government says Deloitte personnel do not provide policy advice to the Commissioner or the Australian government, with policy development and decision-making remaining with public officials. The arrangement has nevertheless drawn scrutiny because Deloitte has previously provided professional services to several tobacco and vaping companies.

Australia Extends Illicit Tobacco Crackdown From Tougher Penalties to Customs and Logistics Supply Chains
Australia Extends Illicit Tobacco Crackdown From Tougher Penalties to Customs and Logistics Supply Chains
Australia's federal government introduced a new illicit tobacco enforcement bill on September 10 that would strengthen evidentiary presumptions, representative sampling, seizure and forfeiture procedures, proceeds-of-crime powers and obligations for customs and logistics operators. The proposal follows the Combatting Illicit Tobacco Act 2026, which took effect in August and increased penalties while expanding investigative and asset-recovery tools. Together, the reforms extend Australia's crackdown from tougher criminal sanctions into import, logistics and evidentiary enforcement.

GSTHR Estimates 200 Million People Use Non-Combustible Nicotine Products as 28 Countries Show Rising Use Alongside Falling Smoking Rates
GSTHR Estimates 200 Million People Use Non-Combustible Nicotine Products as 28 Countries Show Rising Use Alongside Falling Smoking Rates
The Global State of Tobacco Harm Reduction, a project operated by Knowledge·Action·Change, estimates that about 200 million people worldwide use non-combustible nicotine products including vapes, heated tobacco, nicotine pouches and snus. Its 2026 report says use of these products rose alongside declining smoking rates in 28 countries it analyzed. The data do not establish that all 200 million users have quit smoking, nor do they prove a direct causal relationship. GSTHR also says regulatory restrictions on the products continue to expand in many markets.
