From the lying liars at Cleveland Clinic:
Popcorn lung (bronchiolitis obliterans) is a condition that affects your bronchioles. Toxic substances, vaping and infections damage these small airways, which causes breathing problems like coughing, wheezing and shortness of breath.

Now, a truthful article from Cancer Research UK (wish it had a date on it):

So as regards vaping, the ingredient in the hot seat was diacetyl, which imparted a buttery taste to eliquid flavors. As you can see in the UK article, Diacetyl was banned in vape products in the UK, as a safety measure. In the US, most vape makers stopped using Diacetyl voluntarily.
