Hidden Dangers in E-Cigarette Products: A Health Hazard
Duke University researchers reveal tobacco companies substituting unknown, potentially harmful chemicals for nicotine in e-cigarettes to avoid regulations.

According to Mirage News on August 8th, health researchers at Duke University in North Carolina reported that some tobacco companies have started using alternative chemicals with similar characteristics but unknown health impacts to replace nicotine in e-cigarette products in order to circumvent public health regulations.


In a research letter published in the Journal of the American Medical Association on August 7th, researchers from Duke University and Yale University also found that the quantities of these chemicals (known as nicotine analogs) were not accurately disclosed on the packaging.


The study's co-author, Senior Research Scientist Sairam V. Jabba, D.V.M., Ph.D., of Duke University School of Medicine, stated that...


E-cigarette products containing nicotine are restricted by federal law, prohibiting sales to individuals under the age of 21.


Currently, nicotine analogs are not restricted by FDA regulations, and their health effects have not been studied. Our analysis of some e-cigarette products containing analogs sold in the United States found significant and concerning discrepancies between the claimed ingredients and the actual ingredients. Furthermore, manufacturers may be trying to circumvent FDA tobacco regulation.


The study emphasizes that a chemical compound called 6-methyl nicotine is shown in rodent experiments to be more effective and more toxic than nicotine in targeting brain nicotine receptors. Another chemical compound called nicotinamide is advertised as targeting the same brain receptors, although evidence suggests it does not bind to these receptors.


These nicotine analogs are added to flavored e-cigarettes, previous studies have shown that these e-cigarettes are more popular among young people and first-time e-cigarette users.


Jabba and colleagues, including co-senior author Sven Eric Jordt, Ph.D., analyzed a e-cigarette product called Spree Bar, which has at least nine flavors and is labeled as containing 5% 6-methylnicotine. The research findings showed that the actual chemical content was about 88% lower than what was indicated on the label. This e-cigarette also contains an artificial sweetener that is 13,000 times sweeter than sucrose, as well as an artificial cooling agent that mimics the effect of mint.


The second brand of e-cigarette (sold under the names Nixotine, Nixodine, Nixamide, and Nic-Safe) contains a nicotine analogue called niacin, with levels lower than indicated on the label, and combined with an undisclosed amount of 6-methyl nicotine. This brand does not contain any sweeteners or cooling agents.


These products appear to be designed to circumvent laws and regulations aimed at protecting people, especially children, from the harmful effects of smoking and tobacco use. We do not know what effects these chemicals may have when heated and inhaled. These questions should be answered before allowing the products to be marketed.

Product | SnowPlus Launches Nicotine-Free DASH in South Korea, Localising an Established Disposable Platform
SnowPlus has introduced a nicotine-free version of DASH in South Korea, adapting an existing overseas disposable platform for the local market. The Korean version retains the series’ flat duckbill-style mouthpiece, ceramic heating architecture and disposable form factor while reducing nicotine content to 0%. By comparison, the overseas DASH 4000 platform typically features 7.5ml of prefilled e-liquid, up to 4,000 puffs and a 530mAh rechargeable battery, with nicotine-containing variants available in some markets. The product update centers on formulation localisation rather than a new hardware generation.

China’s Zhengzhou Tobacco Research Institute develops end-to-end heated tobacco analysis to trace aerosol compound origins
China’s Zhengzhou Tobacco Research Institute develops end-to-end heated tobacco analysis to trace aerosol compound origins
The Zhengzhou Tobacco Research Institute of China National Tobacco Corporation has filed a patent application for an end-to-end method to analyze the migration and transformation of chemical compounds in heated tobacco products. Using GC-Orbitrap/MS non-targeted analysis, the method compares tobacco substrate and aerosol samples to distinguish compounds transferred directly from the substrate from those newly formed during heating, while also calculating transfer rates. In an example involving nine heated tobacco products, the patent identified 17 newly formed thermal decomposition compounds and 38 transferred compounds.

PMI Expands U.S. ZYN Portfolio With New 1.5 mg and 8 mg Strengths, Moves Toward a Unified 20-Pouch-Per-Can Format
PMI Expands U.S. ZYN Portfolio With New 1.5 mg and 8 mg Strengths, Moves Toward a Unified 20-Pouch-Per-Can Format
Philip Morris International is expanding its U.S. ZYN nicotine pouch portfolio with new 1.5 mg and 8 mg strengths and plans to move its core 3 mg and 6 mg dry-pouch products from 15 to 20 pouches per can in the fourth quarter of 2026. ZYN ULTRA is also commercially available, with FDA authorization covering 10 products at 9 mg and one 11 mg Smooth product. PMI U.S. lists the new 1.5 mg and 8 mg strengths as commercially available, but as of September 10 they do not appear on the FDA’s public authorization list. Public materials do not identify which PMTA submissions cover the two new strengths or their current review status.

How Large Is France’s Off-Channel Tobacco Market? Logista Says It Has Become Structural, While the Official Estimate Is 17.7% and Some Industry Studies Put It Above 50%
How Large Is France’s Off-Channel Tobacco Market? Logista Says It Has Become Structural, While the Official Estimate Is 17.7% and Some Industry Studies Put It Above 50%
Logista France says tobacco consumption outside France’s official tobacconist network has become a large and structural market phenomenon, but official and industry estimates differ sharply. France’s TAFE study estimates that 17.7% of tobacco consumption escaped domestic taxation in 2023, with most of that volume attributed to cross-border purchasing rather than street sales. Some industry studies use broader off-channel definitions and put the figure above 50%. Meanwhile, French Customs seized 547.94 tonnes of tobacco in 2025, up 12%, showing continued pressure from illicit trade.

Australia’s TGA Places Nicotine Pouches Under Therapeutic Goods Rules From July 24, Blocking Imports of Unapproved Products
Australia’s TGA Places Nicotine Pouches Under Therapeutic Goods Rules From July 24, Blocking Imports of Unapproved Products
Australia is strengthening controls on nicotine pouches under its existing therapeutic goods regulatory framework. According to the Therapeutic Goods Administration (TGA), nicotine pouch products must meet regulatory requirements, and unapproved products cannot be legally imported. The move follows Australia’s broader approach of maintaining strict oversight of nicotine products, including nicotine-containing vapes. As nicotine pouches expand globally, Australia’s regulatory approach highlights growing differences in how countries manage emerging smoke-free nicotine products.
