> use a liquid that doesn't contain nasty chemicals that cause popcorn lung syndrome, e.g. diacetyl

The levels of diacetyl found in (certain) vape liquids are probably not a concern. Cigarette smoke contains much higher concentrations of diacetyl and popcorn lung doesn't appear to be endemic in smokers.

Indeed most of the cases in medical literature seem to involve factory workers who were exposed to high amounts of diacetyl, plus a handful of people who consumed massive amounts of microwave popcorn. Are there any observed cases of popcorn lung in smokers?

Interesting. Thanks. Perhaps the idea of particular vaping liquids causing popcorn lung is a myth too. Here's an article I've found that includes some references to research: https://www.snopes.com/fact-check/vaping-causes-popcorn-lung...
