Ask AI: Is popcorn lung a myth, or is it real?

Popcorn lung, also known as bronchiolitis obliterans, is a real and serious medical condition. It is caused by inhaling certain chemicals, such as diacetyl, which were previously used as flavorings in microwave popcorn and some e-cigarette products. It can cause scarring and narrowing of the airways in the lungs, resulting in respiratory symptoms like coughing, wheezing, and shortness of breath. While the use of diacetyl in food flavorings has been banned in most countries, it is still important to be aware of the possible risks associated with inhaling certain chemicals, especially when using e-cigarettes or other vaping products.
