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.

Special Report | Altria Subsidiaries Sue FDA to Vacate 2021 PMTA Rule as Agency Moves to Speed Reviews
2Firsts reviewed the original federal court complaint filed by Altria subsidiaries Helix Innovations and NJOY on Sept. 2 challenging FDA’s 2021 PMTA rule. The lawsuit questions whether FDA’s review process complies with the Tobacco Control Act’s 180-day timeline, even as the agency moves to accelerate PMTA reviews and issues more marketing orders. Drawing on the complaint, FDA records, government audits and recent court rulings, 2Firsts examines the legal arguments, supporting evidence and potential implications for the U.S. tobacco review system.

Japan Tobacco International is stepping up its heated tobacco push in South Korea with Ploom AURA. Since its official launch in April 2026, the device's limited First Edition and Glacier White version have sold out, while distribution has expanded across Seoul, Incheon, Gyeonggi Province and airport duty-free channels. The rollout marks JTI's third major attempt to build a stronger heated tobacco position in South Korea, following Ploom TECH in 2019 and Ploom X Advanced in 2024. At the group level, JT plans to invest about ¥800 billion, approximately $5 billion, in reduced-risk products from 2026 through 2028, with heated products and Ploom identified as its primary investment priority.

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.
