New Study by Yale University Raises Concerns About E-Cigarettes
Yale study reveals some e-cigarettes may contain potent nicotine-like chemicals, raising health concerns beyond FDA regulation.

According to a report by Newsweek on August 12, a previous study by Yale University found that some e-cigarettes may contain chemical compounds similar to nicotine that could have unknown effects on health.


These nicotine alternatives interact with receptors in the brain, without being subject to FDA restrictions and regulations. As a result, these products are able to be marketed with flavors that appeal to young people and avoid tobacco taxes.


An FDA spokesperson stated that these new chemicals may be more potent than nicotine and could potentially affect the brain development, learning abilities, and memory of adolescents.


FDA Public Affairs Specialist Jim McKinney told Newsweek that...


The FDA is addressing this issue from the perspective of the entire agency and will continue to utilize all resources within its authority to protect the public, especially American adolescents, from potentially harmful addictive products.


McKinney points out that, although more research is needed, some emerging data suggests that these nicotine analogs may be more potent than nicotine itself, which is already highly addictive, altering adolescent brain development and producing long-term effects.


According to research, nicotine analogs are chemical substances that are structurally very similar to nicotine and therefore target the same receptors in the brain. Examples include 6-methyl nicotine and nicotineamide. A study in rodents suggests that 6-methyl nicotine may be more toxic than nicotine. Furthermore, because these compounds are not subject to the same strict regulations as traditional nicotine, the ingredients listed on labels may not always match the actual ingredients in the products.


Dr. Hanno Erythropel, a scientist at the Yale School of Medicine, stated in a press release,


In conclusion, the company is actually trying to evade regulation by introducing new products containing nicotine analogues with unknown health and addiction risks.


In a study published in the journal "JAMA Network," the researcher and their colleagues analyzed two e-cigarette and e-liquid products on the market. The first product, Spree Bar, claimed to contain 5% of 6-methyl nicotine (50 milligrams/gram), while the second product, Nic-Safe, was tested at four concentrations—0, 12, 24, and 36 milligrams/milliliter.


The research results show that both products do not contain the ingredients as specified on their labels. Spree Bar actually contains 90% less 6-methyl nicotine than advertised, while Nic-Safe contains a low concentration of 6-methyl nicotine without it being clearly marked on the label (excluding tested nicotine-free products).


FDA spokesperson Mackinney said that


In general, the FDA does not comment on specific studies, but instead uses them as part of the evidence to further understand specific issues and help achieve its mission of protecting public health. Regarding nicotine mimetics, the FDA is aware that some companies are reported to be producing products that may contain compounds with chemical structures or properties different from nicotine.

Smoore Seeks to Toss CCELL Price-Fixing Claim as Court Weighs Vertical Distribution Versus Horizontal Conspiracy
Smoore Seeks to Toss CCELL Price-Fixing Claim as Court Weighs Vertical Distribution Versus Horizontal Conspiracy
Smoore and four authorized U.S. CCELL distributors are asking a California federal court to permanently dismiss a core antitrust claim brought by direct purchasers. Plaintiffs allege that Smoore coordinated minimum wholesale prices, customer allocation and limits on price competition among distributors, amounting to a per se unlawful horizontal conspiracy. The defendants say the alleged conduct reflects ordinary vertical relationships between a manufacturer and its distributors. The court previously dismissed a similar claim, and the latest dispute centers on whether the second amended complaint adds sufficient facts to establish a horizontal agreement.

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.

U.S. Customs Plan to Require Foreign Export Declarations Could Deal ‘Devastating’ Blow to China’s Vape Exports, Logistics gl Expert Says
U.S. Customs Plan to Require Foreign Export Declarations Could Deal ‘Devastating’ Blow to China’s Vape Exports, Logistics gl Expert Says
A U.S. Customs and Border Protection proposal to collect foreign export declarations and other overseas customs documents could expose discrepancies in the value, classification and description of China-made vape shipments entering the United States. A veteran Chinese logistics professional told 2Firsts that the measure, if implemented, could undermine the all-inclusive shipping model used by some unauthorized vape exporters and push parts of the trade toward costlier underground channels. The risk extends beyond higher duties: accurately declared products may also be more readily identified as unauthorized e-cigarettes subject to FDA enforcement.

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.

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.
