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.

Special Report|CrossBar's High-Puff Vapes Draw Attention on Pennsylvania's 163-Product Directory as Link Between Earlier 1.3mL PMTA Filings and New 13mL Products Remains Unclear
Special Report|CrossBar's High-Puff Vapes Draw Attention on Pennsylvania's 163-Product Directory as Link Between Earlier 1.3mL PMTA Filings and New 13mL Products Remains Unclear
Pennsylvania began enforcing its electronic nicotine delivery system directory restrictions on October 19, 2026. Among 163 product listings recorded before enforcement, four CrossBar 20K disposables stood out with 13mL capacity, advertised puff counts of up to 20,000 and a flattened design distinct from conventional pod systems and compact disposables. Historical records identify earlier 1.3mL CrossBar products associated with Romo LLC, while newer 13mL products appeared in several state directories beginning in 2025 under entities including Blue Nine LLC. PMTA compliance expert Mr. K identified amendments and application ownership transfers as possible regulatory mechanisms, although neither has been confirmed in this case. Separately, Reynolds' $7.5 million acquisition of 16 PACHA products and related assets illustrates the commercial value of products linked to historic PMTA submissions.

Virginia's new retail tobacco permit system took effect October 1, requiring sellers of vapes, nicotine products and related devices and accessories to obtain a Retail Tobacco Permit for each business location.

Qualifying applicants that filed before October 1 may temporarily operate under a Letter of Authorization. The new store-level permit also sits alongside Virginia's existing vape product directory, where sales of unlisted liquid nicotine or nicotine vapor products can trigger civil penalties starting at $5,000.

PMI Pushes Smoke-Free Business in Latin America as Argentina Lifts Heated Tobacco Ban, Mexico City Share Tops 7%
Philip Morris International (PMI) showcased IQOS heated tobacco systems and nicotine pouch products at Technovation 2026 in Buenos Aires on October 7–8, presenting research on consumer attitudes, regulatory developments and illicit cigarette trade across Latin America. PMI Chief Global Growth Officer Stefano Volpetti said smoke-free products accounted for more than 7% of the Mexico City market. Argentina repealed its heated tobacco ban in May 2026 and introduced registration requirements for tobacco and nicotine products, while local media reported nicotine pouch sales in Mendoza. A PMI-commissioned survey found that only 8% of respondents across four Latin American countries were familiar with nicotine pouches. A separate KPMG study estimated illicit cigarette consumption at 77 billion sticks across 11 markets in Latin America and Canada in 2025.

Global Nicotine-Pouch E-Commerce Group Haypp Shuts Sweden’s Snusnetto Over Age Verification as Identity Checks Become Industry Infrastructure for New Nicotine Products
Global Nicotine-Pouch E-Commerce Group Haypp Shuts Sweden’s Snusnetto Over Age Verification as Identity Checks Become Industry Infrastructure for New Nicotine Products
Sweden's Supreme Administrative Court has declined to hear an appeal over age verification for tobacco and nicotine products collected from parcel lockers, leaving in place a lower-court ruling that geo-located BankID verification is insufficient to securely verify the actual recipient. Haypp Group has stopped tobacco and nicotine sales through Snusnetto and is deploying a new system across its other Swedish e-commerce sites to verify the age of the person who actually opens the locker and receives the shipment. The change comes as age verification across next-generation nicotine products expands from purchase checks into retail, delivery and, for some e-cigarettes, device access itself.
