The study found that mint-flavored e-cigarettes are carcinogenic

U.S. researchers found that e-cigarettes flavored with mint and menthol, as well as the potential carcinogen huminsterone in smokeless cigarette products, exceeded the standard, adding a new health risk to e-cigarettes.
ketones are an extract component of mint plants and may cause liver cancer, deformation of lung tissue, and metamorphosis in mice. The World Health Organization lists hue mintone as a potentially carcinogenic Class 2B carcinogen, and the U.S. Food and Drug Administration last year banned the use of hue mint as a food additive.
Duke University School of Medicine tested six types of e-cigarettes and non-smoking cigarettes containing hu mint ketones. It was found that the exposure limit of lynum in e-cigarette liquid was between 325 and 6012, and smokeless cigarettes were between 549 and 1646, all of which had a risk of cancer.
the FDA stipulates that the "exposure limit" for carcinogens (i.e., maximum non-carcinogenic use divided by expected daily use) must not be less than 10,000. The lower the number, the greater the health risk.
in a paper published in the Journal of the American Medical Association, the team said that the daily exposure to huminol, which uses these scented e-cigarettes, is about 86 to 1,600 times higher than that of mint-flavored flammable cigarettes. Panais Galliasatos, director of the Tobacco Therapy Clinic at Johns Hopkins University in the United States, called the findings "highly worrying."
U.S. Department of Health and Human Services announced Monday that it will introduce rules in the coming weeks to ban the sale of non-tobacco-flavored e-cigarette products to control the trend of e-cigarette use among teenagers. U.S. health authorities have repeatedly suggested the health risks of e-cigarettes, and are investigating more than 450 cases of severe lung disease linked to the use of e-cigarettes. Early last month, the FDA said it had received 127 reports of seizures after using e-cigarettes and was investigating whether e-cigarettes were the direct cause.
e-cigarettes consist mainly of batteries, heating evaporation devices and a pipe filled with fumes, which can be atomized to turn nicotine-containing fumes into vapors for the user to inhale. WHO has published a report that there is insufficient evidence that e-cigarettes help to quit smoking and that smokers can only benefit most from the complete withdrawal of nicotine.
