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.
