> Flavoring compounds, though... there are liquids out there that contain diacetyl (a "buttery" flavoring).
That name rang a bell; diacetyl is the compound behind "popcorn lung", so called because its use for its buttery taste in microwave popcorn was common but is damaging to the lungs if the fumes were inhaled; e.g. https://nyti.ms/2h7ls4G. Interesting to see that it's being used as a vaping flavorant.
