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.

2Firsts First Look|China to End VAT Export Rebates on Vape Devices and Nicotine in April 2027, Following Earlier Removal for HTP Devices and Nicotine Vapes
2Firsts First Look|China to End VAT Export Rebates on Vape Devices and Nicotine in April 2027, Following Earlier Removal for HTP Devices and Nicotine Vapes
China's Ministry of Finance and State Taxation Administration announced on October 12, 2026, that value-added tax (VAT) export rebates for vape devices, nicotine and its salts, and certain non-combustible inhalation products will be eliminated from April 1, 2027. The measure adds four tobacco- and nicotine-related customs codes, including 8543400010, which covers vape devices and qualifying empty pods. China previously eliminated rebates for nicotine-containing vaping products and devices under code 8543400090 in April 2026. According to industry classification information held by 2Firsts, the latter currently corresponds to heated tobacco devices. Export excise tax refund and exemption arrangements will remain unchanged.

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.

U.S. Health Groups Seek to Overturn FDA Enforcement Discretion for Pending PMTAs as Altria's Helix, NJOY and AVM Move to Intervene
American Vapor Manufacturers (AVM) and Altria subsidiaries Helix Innovations and NJOY filed separate motions on October 7, 2026, seeking to intervene on the FDA's side in a lawsuit challenging its enforcement guidance for certain e-cigarette and nicotine pouch products with pending premarket tobacco product applications (PMTAs). Seven public health and tobacco-control organizations, including the Campaign for Tobacco-Free Kids, sued the agency in July to overturn the policy. AVM argues that vacating the guidance could disrupt orders, inventory, retail distribution and investments in regulatory submissions.

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.
