which make inhaled nicotine feel gentler on the throat and are more potent because they allow people to inhale higher concentrations of nicotine without discomfort the ease of vaping with juuls wildly popular sleek devices and the addictiveness of high levels of nicotine could have led some people to vape more and more exposing them to higher amounts of potential toxins like flavorings and to overdoses of nicotine which can make people feel quite sicka study published in 2017 found increased rates of chronic cough and other respiratory problems in teenagers who vaped nicotine including those who had never smoked cigarettesresearch published last week on adults found that while ecigarette users were better off than smokers they were more likely than nonsmokers to develop respiratory disease the risk was greatest among those who both vaped and smoked which was common one of the new articles published on friday in the new england journal of medicine strengthens the case against vitamin e acetate reporting that it was found in lung fluid from 48 of 51 people with the vaping illness 94 percent earlier research had made the same finding but in a smaller number of patientsthe 51 patients came from 16 states indicating that vitamin e acetate was in widespread use and not from just a single local supplier of tainted products dr schuchat said the new study compared the patients with 99 healthy people who had previously given samples of lung fluid as part of other research on smoking that involved nonsmokers smokers and vapers none of the healthy people had the vitamin e additive in their lungsresearchers dont know how vitamin e acetate could harm the lungs but they suggested two possible ways it could disrupt a substance called surfactant which helps keep open tiny air sacs deep in the lungs and is essential for normal breathing a second theory is that the heat of vaping could break down the vitamin e acetate into ketene a dangerous molecule that might produce the kind of chemical burns found in the lungs of some patientsboth ideas need more study and testing in animals the researchers saidthe vitamin e acetate was first found in a thcvaping product from a sick patient that was analyzed in august by scientists at the new york state department of healths wadsworth centersince then the center has found the substance in more than 100 thc samples about 69 percent of all the thc vaping cartridges it has tested david c spink director of the organic and analytical chemistry lab said in an interview most of the samples are 40 percent to 50 percent vitamin e acetate dr spink said the lab has also tested six products marketed over the internet to dilute thc for vaping they came in brown bottles with nice professional looking labels on them but they didnt have a list of ingredients dr spink said three of the six were pure vitamin e acetate science times page on facebook sign up for the
