![]() Why are the flavorings allowed? Excluding the above offenders, most of the chemicals that add flavor are actually formulas that have been approved by the FDA for use in food, Glantz explains. ![]() What’s more, diacetyl-a chemical known to wreak havoc on your respiratory system and cause “popcorn lung”-was found in more than 60 percent of the samples. Meanwhile, research out of UNC Chapel Hill reports cinnamon flavoring in particular likely impairs respiratory immune cell function, lowering your ability to fight off an infection in the respiratory tract.Īnd that’s just the tip of the iceberg of the harm flavorings pose: One 2017 Harvard study analyzed 24 different flavored e-cigarette brands and found all had at least one aldehyde or flavoring chemical on the FEMA “High Priority Chemicals” or FDA Harmful and Potentially Harmful Constituents lists. Vaping also lowers your ability to fight off an infection: E-cigarette liquid and vapor harm alveolar macrophages, our main respiratory immune response that gets rid of infections, toxins, and allergens, according to a 2018 study in British Medical Journal Thorax. For one, the two chemicals found in all e-cigarette liquid-propylene glycol and vegetable glycerin-are the same compounds used in a fog machine, and an older study found theatrical workers often exposed to this mist formula had increased dyspnea (labored breathing), chest tightness, and wheezing. They’ll Still Tear up Your lungs-Especially Flavored E-cigsĪ large study review last year in the Annual Review of Public Health found despite having certain benefits over traditional cigarettes, the electronic kind still exposes you to high levels of ultrafine particles and other toxins that can increase your risk of non-cancer lung disease (and cardiovascular disease)-at rates similar to conventional cigarettes. Plus, if you’re a lifelong e-cig user, even that low level of carcinogen exposure will catch up with you. ![]() “E-cigs are different from cigarettes and they produce a different mixture of toxicants, most of which we don’t even know about yet since people have been studying e-cigs for a fraction of the time we’ve been studying cigarettes,” says Glantz. Most importantly, just because e-cigs deliver less carcinogens doesn’t mean they’re harm-free. “Once you reach the point of dry vaping-continuing to puff at the bottom of the cartridge until there’s no liquid left-there’s nothing to cool down that coil, so the burning creates higher amount of toxins,” Foulds explains. There are a few bad habits that override this benefit, though: If you keep smoking on top of vaping-like most e-cig users do-you’re actually putting more chemicals into your body and draining the vape to the last drop creates its own set of health concerns. The vapor that comes out of e-cigarettes isn’t harmless, but it has maybe 10 to 20 chemicals compared to a cigarette’s thousands, in part because you aren’t getting the chemical reactions from combustion, he explains. “There are more than 7,000 chemicals in cigarettes, including dozens of carcinogens,” says Jonathan Foulds, Ph.D., a professor of public health sciences and psychiatry who studies smokers and tobacco products at Penn State University. They Fill Your Lungs With Less Carcinogens Than CigarettesĬompletely switching over from regular smokes to e-cigs lowers your exposure to toxicants and carcinogens, confirms a 2018 position paper in JAMA. Swapping Out Cigarettes for Vapes Could Prevent Millions of Premature Deaths, Sa.
