In a 2019 report from the University of Rochester, 11 of 12 patients (92 percent) who were admitted to the hospital for vaping-related illness had used an e-cigarette product that contained THC. None was found in similar fluid from participants who didn’t have EVALI. While the exact cause for the EVALI cases hasn’t been identified, CDC reports that laboratory data suggests vitamin E acetate, an additive in some THC-containing vaping products is “strongly linked” the EVALI outbreak.Ī recent study of 51 individuals with EVALI found that vitamin E acetate was found in the lung fluid of 95 percent of them. Over the last year, e-cigarette, or vaping, product use–associated lung injury (EVALI), which include bronchiolitis obliterans from diacetyl exposure (aka: popcorn lung) have skyrocketed in people who vape.Īccording to the Centers for Disease Control and Prevention (CDC), as of February 18, 2020, there have been 2,807 confirmed cases of EVALI in the United States and 68 confirmed deaths. If you’ve watched the news lately, chances are you’ve heard about the illnesses and controversies associated with vaping.
Other conditions that have been linked to popcorn lung include rheumatoid arthritis and graft-versus-host disease, which happens after a lung or bone marrow transplant. The lung condition now known as popcorn lung was first discovered when workers in a popcorn factory developed breathing problems after inhaling diacetyl, a chemical that’s used to give foods a buttery flavor.ĭiacetyl is also found in some liquids that are inhaled through an e-cigarette. Popcorn lung is caused by breathing in certain harmful chemicals or substances, some of which are found in e-cigarettes. Popcorn lung occurs when bronchioles become scarred and narrow, making it harder for your lungs to get the air they need. The bronchi then split into smaller tubes called bronchioles, which are the smallest airways in your lungs. The trachea then splits into two airways, called bronchi, that each lead to one of your lungs. When you take a breath in, air travels into your airway, also known as your trachea.
It can cause scarring and narrowing of these important airways, leading to wheezing, shortness of breath, and coughing. Popcorn lung, or bronchiolitis obliterans, is a disease that affects the smaller airways in your lungs called bronchioles.
