What are the chances that Vaping CBD will give me a popcorn lung and other related illnesses?

The chances that vaping CBD will give you popcorn lung are literally zero. The popcorn lung claim has to do with diacetyl, a common ingredient in artificial flavors like butter and caramel. There's no diacetyl in CBD vapes. An outbreak in vaping-related illnesses also caused a huge stir, with researchers concluding that vitamin E acetate was a likely cause. This is a cutting agent found in illegal THC vape cartridges, but it may also be a listed ingredient in hemp CBD vapes. Don't consume products containing that ingredient.
