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.

JTI Proposes 25-Cent Irish Cigarette Tax Increase, Says It Could Raise €45 Million
JTI Proposes 25-Cent Irish Cigarette Tax Increase, Says It Could Raise €45 Million
Japan Tobacco International's Irish business has proposed a €0.25 tax increase on a pack of 20 cigarettes in its pre-Budget 2027 submission, below the €0.50-or-more increases typically imposed in recent Irish budgets. JTI says the proposal could generate around €45 million in additional Exchequer revenue while limiting further movement toward illicit and non-Irish-tax-paid tobacco. Revenue's existing estimate for a comparable €0.25 increase, including pro-rata rises on other tobacco products, is about €18 million for a full year.

Philippines Mandates Safety Certification for Nicotine Pouches, Gives Industry 12 Months to Comply
Philippines Mandates Safety Certification for Nicotine Pouches, Gives Industry 12 Months to Comply
The Philippines Department of Trade and Industry has placed nicotine pouches under mandatory product certification through Department Administrative Order No. 26-07, Series of 2026. Nicotine pouches must obtain a Philippine Standard, or PS, license before they can be manufactured, imported, packed, distributed or sold in the country. The regime requires testing for nicotine content, pH and water activity, while packaging must disclose nicotine strength, ingredients, allergens, batch information, the PS certification mark and prescribed health warnings. Existing market participants have a 12-month transition period to comply.

NAS 2026 | FDA CTP Director Says PMTA Pathway Is “Predicated on Tobacco Harm Reduction”
At the 2026 New Approaches Summit in New York, FDA Center for Tobacco Products Director Bret Koplow said the PMTA pathway is “predicated on tobacco harm reduction.” He outlined four CTP priorities: youth prevention, helping adults quit or switch to lower-risk products, improving relative-risk communication, and reducing unauthorized products. Koplow also addressed flavored e-cigarettes, public risk perceptions, industry credibility and efforts to make PMTA reviews more efficient and predictable.

GAO Audit Finds Nearly 132,000 FDA Tobacco Applications Waiting an Average 1,266 Days as Nicotine Pouch Pilot Practices Move Into Vape PMTA Reviews
GAO Audit Finds Nearly 132,000 FDA Tobacco Applications Waiting an Average 1,266 Days as Nicotine Pouch Pilot Practices Move Into Vape PMTA Reviews
A U.S. Government Accountability Office audit found that 131,915 tobacco product applications submitted to the FDA since 2018 remained without a final review as of December 31, 2025, with pending applications waiting an average of 1,266 days. GAO also found FDA lacks the data needed to systematically determine whether scientific reviews meet applicable timelines. HHS agreed to upgrade the agency's tracking systems. At the same time, FDA has begun applying lessons from its nicotine pouch PMTA pilot to e-cigarette reviews, while changes to enforcement policy and electronic submissions are making the specific stage of a PMTA increasingly relevant to market access.
