Study finds reduced toxicity of ENDS compared to cigarettes.
Researchers validated reliability of results. Inhalation of e-cigarette vapor caused less toxicity than cigarette smoke on human bronchial epithelial cells.

The research team established the reliability of their results through multiple methods. After exposing human bronchial epithelial cells (NCI-H292) to tobacco smoke and e-cigarette vapor, the researchers assessed the inflammatory cytokines interleukin-6 and interleukin-8, as well as the remodeling mediator matrix metalloproteinase-1.


Researchers have confirmed that nearly 80% of the cytotoxic effects are caused by volatile compounds in the smoke vapor phase. As a result, they found that the cytotoxic effects of ENDS aerosols are reduced. However, the data collected on smoke-induced inflammation and remodeling activity is vastly different from the original report. Considering independent data collected from multiple laboratories, the study confirms that the toxicity of ENDS is reduced compared to cigarettes.

Australia Adds 6-Methylnicotine to Schedule 9 Prohibited Substances, Effective October 1
Australia Adds 6-Methylnicotine to Schedule 9 Prohibited Substances, Effective October 1
Australia's Therapeutic Goods Administration published a final decision on September 25 to classify 6-methylnicotine as a Schedule 9 prohibited substance under the Poisons Standard, effective October 1, 2026. TGA said the chemical has been reported in e-cigarette liquids sold in Australia and marketed as nicotine-free or nicotine alternatives, while evidence also indicates its use in preparations such as oral pouches. The government originally proposed a Schedule 7 classification but ultimately adopted the stricter Schedule 9 designation, citing acute toxicity, dependence risk, use in unapproved consumer products and misleading marketing.

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.

German Tobacco Tax Revenue Falls 10.8% Through August as Tax-Paid Cigarette Volume Drops 12.6%
German Tobacco Tax Revenue Falls 10.8% Through August as Tax-Paid Cigarette Volume Drops 12.6%
Germany collected €9.789 billion in total tobacco tax revenue from January through August 2026, down 10.8% from a year earlier, according to the Federal Ministry of Finance. Germany's tobacco tax base covers not only cigarettes and fine-cut tobacco but also heated tobacco and vaping liquids taxed as tobacco substitutes. The German Association of the Tobacco Industry and Novel Products, or BVTE, citing federal statistical data, said tax-paid cigarette volume fell 12.6% to 40.6 billion sticks. BVTE is using the latest figures to argue against further tax increases planned from 2027 through 2030, while Germany's parliament is scheduled to hold a first reading of the bill on September 24.

Pennsylvania Vape Directory Law Survives Court Challenge From Nova Distro and Others Amid Similar Rulings Across States
Pennsylvania Vape Directory Law Survives Court Challenge From Nova Distro and Others Amid Similar Rulings Across States
A U.S. federal court upheld Pennsylvania's vape directory law on October 14, rejecting a challenge brought by Nova Distro, 101 Distributors and companies operating Tobacco Hut retail stores. Court records show that vaping accounts for about 60% of Tobacco Hut's profits and that the chain held approximately $2 million in inventory potentially subject to seizure under the law as of June 2. Pennsylvania began enforcement on October 19. The ruling follows similar appellate decisions in other states, even as new research shows that unlisted vaping products continue to account for substantial sales in states with established directories.

U.S. Expands Illicit Vape Enforcement as ATF Brings PACT Act Powers Into Trade Fraud Task Force
U.S. Expands Illicit Vape Enforcement as ATF Brings PACT Act Powers Into Trade Fraud Task Force
The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives said on September 23 that it has joined the interagency Trade Fraud Task Force to strengthen enforcement against illegal, misdeclared and smuggled vape and tobacco products. ATF will bring its authority under the Prevent All Cigarette Trafficking Act into the task force, including registration, reporting, shipping and record-inspection requirements covering interstate sales of electronic nicotine delivery systems. ATF said the move will strengthen its ability to trace illicit products from U.S. points of entry through domestic trafficking and distribution networks.

Special Report | Vape bans and tougher rules: the South Caucasus takes different paths
Azerbaijan's sweeping e-cigarette ban has raised concerns over enforcement errors and the emergence of illicit sales, while neighboring Armenia is tightening technical rules and preparing higher excise taxes. Georgia, meanwhile, has resisted calls for broader vape restrictions and introduced preferential taxes for some domestically produced cigarettes. The divergent approaches across the South Caucasus highlight a regional policy dilemma: how to curb nicotine use and protect public health without encouraging black markets or creating unintended economic consequences for businesses and consumers.
