Is e-cigarette to become In the last two decades, rapidly popular, especially among young people. These smooth, delicious taste smoking devices are often marketed as a safe alternative to traditional cigarettes, but threatening new research challenges.
In a study published on 25 June in the journal Central scienceResearchers tested dangerous metals and metaloids such as lead, chromium, antimony and nickel tested the brands. Increasing these toxins can increase the risk of cancer, respiratory disease and nerve damage. Conclusions suggest that e-cigarette toxic metals emit highly high levels-the order of more magnitude than the levels emitted by traditional cigarettes and other e-cigarettes. One brand released more lead during one day Use About 20 pack cigarette packs. Given the widespread use of vapes, the conclusions underline the immediate need for regulatory action, concluding the researchers.
“Our study highlights the hidden risk of these new and popular disposable electronic cigarettes–Emphasis emphasizes the need for urgency in the enforcement with the nurotoxic lead and carcinogenic nickel and dangerous levels of the antimony,” Co-author Brett Polyin, a supportive professor of environmental toxic science in the University of Californea, said a supportive Professor, Davis, a tributary said, one said. statement“These risks are not worse than other e-cigarettes, but in some cases compared to traditional cigarettes.”
The Food and Drug Administration (FDA) has torn the brands of tasting, disposable vep selling in the US due to concerns about the access, health risk and unauthorized sales of the youth. Despite this Ongoing Warning letters to popular brands, Slap Retail seller with civilian punishment, and Blocked E-cigarette imports from other countries, such as China, have failed to keep these devices out of the US market.
Over the years, the sales of disposable veps have overtaken the sale of old, refillable veps. According to FDA Annual national youth tobacco survey For 2025, disposable e-cigarette is the most commonly used tobacco product among young people. The survey found that 5.9% middle and high school students (1.63 million) reported the current use of e-cigarettes, and 55.6% of those students use disposable vep.
Previous studies have examined the fundamental structure of refillable e-cigarettes, but some have noticed these new equipment. To fill that difference, Palin and his colleagues analyzed metals and metaloids inside the seven disposable vep made by three brands, including the taste and unaffected fluid. He selected brands based on popularity and bought e-cigarettes from online vendors located in the US, testing nicotine except one except one, which allows researchers to test whether nicotine affects the metal concentrations of e-ekes (usually known as “VAPE Juice”).
The major component of any VAPE is known as a battery, e-leane (usually “Vape Juice” or “E-Juice), and a heating coil. When the user presses a button on the device or in some cases heats the inhales, then heats the horoscope and turns the horoscope into an aerosol.
Researchers tested unused e-tail and metal concentrations of aerosol, using a special tool to activate the e-cigarette and generate between 500 and 1,500 puffs per device. He found that “toxins in these disposable devices are already present in the e-faction, or they are leaching on e-lengths with their components on a large scale and have finally shifted to smoke,” said a PhD candidate, Mark Tarszer, a PhD candidate in the Polin laboratory.
Some unused e-liquids consisted of high level of antimony, a toxic metaloid. The heating coil leacked Nickel in e-towel, while some devices led the bronze alloy components and led Nickel and lead. The vapor of some devices has surprisingly high metal levels, including antimony and lead. Interestingly, the metal concentration of aerosol increased as the number of puffs increased, suggesting that the device deteriorates as the exposure as age.
Overall, researchers determined that disposable e-cigarette users are made aware of high levels of toxic metals and metaloids, which use refillable vAPEs, which can increase health risk. Three vapors of the tested VAPEs were produced which included nickel levels that were higher than cancer risk threshold, and two emitted potential cancer volume antimony. The four devices had nickel and lead emissions that crossed the risk threshold for diseases in addition to cancer, such as neurological damage and respiratory disease.
Among the about 100 disposable e-cigarette brands available in the US, this study tested only three. Despite regulatory efforts, these devices are wildly popular among teenagers. Researchers hope that their job motivates others to examine health risks associated with disposable e-cigarettes, as it appears that they will never be away soon.
