Teener nearly lost his lungs to vaping
The case, described Thursday in the Canadian Medical Association Journal (CMAJ), deepens the mysteries surrounding e-cigarettes, which have grown so popular US President Donald Trump earlier this week backed away from a proposed ban on certain vaping flavors, fearing such a move could cost him votes. READ: Advocacy group seeking law banning minors from vaping Vaping has been blamed for 42 deaths in the United States since the past summer. Canada has been relatively spared, with only eight identified patients, and no deaths. The CMAJ study centers around a 17-year-old male vaper who was in good health and vaping daily, particularly green apple and cotton candy flavored refills as well as those containing THC, the psychoactive component of marijuana which Canada legalized in October of last year. The lesions that appeared in his lungs differed from those seen in the US, where more than 2,000 people have fallen ill from what authorities call e-cigarette, or vaping, product use associated lung injury (EVALI). In the US, the lungs of patents presented various injuries, but mainly alveolar lesions in the air sacs at the end of the airways. Some had suffered chemical-like burns. US investigators have recently concluded that the culprit is vitamin E oil, which is added to liquid e-cigarette refills, particularly those containing THC. But in Canada, doctors in the CMAJ study determined the lungs of the young vaper suffered from bronchiolitis obliterans, which is inflammation of the small airways off the lungs called bronchioles. The patient had gone to the emergency room after developing a persistent cough and doctors, believing he had pneumonia, first prescribed antibiotics, before hospitalizing him and putting him on life support.
