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.

U.S. Rep. Krishnamoorthi Questions FDA Over Planned PMTA Rewrite, Seeks Communications With Altria and Reynolds
U.S. Rep. Raja Krishnamoorthi on Oct. 6 questioned the FDA over its plan to reassess and potentially replace the 2021 PMTA regulatory framework, asking the agency to identify provisions it may change or eliminate, state whether current scientific evidentiary standards will be maintained, and disclose communications with Altria, Reynolds and other parties challenging the rule. Krishnamoorthi led a congressional investigation into JUUL and youth vaping in 2019 and has since remained active on e-cigarette regulation and enforcement.

Special Report | From Oversupply to Supply Gaps: Global Tobacco Leaf Markets Diverge Ahead of 2027

U.S. demand improved in some leaf categories, but growers in Brazil, Colombia, Tanzania and Zimbabwe faced pressure from prices, buyer access, costs and weather. With nicotine consumption patterns also shifting, 2027 will test whether supply, demand and grower profitability can move back toward balance.

Beyond IQOS ILUMA, PMI Expands Lower-Priced BONDS Heated Tobacco Platform: Seven Markets Added in Q3, With Rollouts in Japan, Europe and North Africa
Philip Morris International (PMI) is expanding the international footprint of BONDS by IQOS, its lower-priced heated tobacco platform.

In November, PMI announced plans to extend sales from three to 17 Japanese prefectures and introduced BONDS in Spain and Morocco. The platform uses ROUNDHEAT external heating technology and proprietary tobacco sticks, separate from the IQOS ILUMA system. In Japan, BONDS retails for ¥2,980, approximately 25% below ILUMA i ONE, while BLENDS costs ¥570 per pack. PMI management says BONDS targets cigarette smokers who have not adopted heated tobacco. Separate sales and revenue figures remain undisclosed.

Russia's Vape Ban Decisions Reach 17 Regions With 39 More Considering Laws, Putting Over 3,000 St. Petersburg Retail Outlets in Focus
Russia's regional vape retail restrictions are expanding. State Duma Speaker Vyacheslav Volodin said on November 7 that 17 regions had adopted decisions to ban vape sales, while another 39 were preparing or considering similar legislation. On November 12, lawmakers in Leningrad Oblast and the Republic of Karelia adopted bans scheduled to begin on March 1, 2027. A day earlier, St. Petersburg unanimously approved a five-year ban proposal in its first reading. The city has 615 specialist vape shops and more than 2,400 other retail outlets selling vaping products alongside other goods. Under Federal Law No. 186-FZ, enacted in June 2026, Russian regions may prohibit retail sales of electronic nicotine delivery systems and related liquids between March 2027 and March 2032. The legislation also restricts licensed suppliers from delivering covered products to retail premises in regions where bans apply.

Japan Survey Finds 49.5% Would Cut Tobacco Use if Prices Rise, 64.6% Show Interest in Nicotine-Free Alternatives
Japan Survey Finds 49.5% Would Cut Tobacco Use if Prices Rise, 64.6% Show Interest in Nicotine-Free Alternatives
A September online survey commissioned by Japanese smoking-accessories company Lightec found that 49.5% of respondents would consider reducing tobacco use if prices rose further, while 25.1% would consider switching to cheaper brands and 14.5% would consider using or combining alternatives such as vapes and nicotine-free herbal sticks. Another 64.6% expressed some level of interest in such alternatives. The survey covered 1,088 respondents aged 20 to 70 and was conducted by a company that sells NICOLESS nicotine-free vaping and herbal-stick products, meaning its findings should not be treated as representative of Japan's smoking population.
