Is it the microwaves effect on the popcorn, or the fake butter that might cause "popcorn lung" if the fumes get inhaled, getting modified into PFAs by microwaving?
If it's the first, I'd expect almost everything you nuke to be at least a risk of PFAs. If its the second, that's easier to deal with by avoiding fake popcorn butter.
