To be fair, asbestos is still all over the place. They did this fun thing where they just reclassified different asbestos structures into different categories and banned some of them.
My guess for another substance that isn’t asbestos will be either PFAS or we’ll finally find out what all these micro/nanoplastics are doing to us.


This is about right. Teflon (PTFE) itself is mostly harmless to humans because you aren’t likely to consume large enough amounts or small enough particles of Teflon for it to enter your bloodstream.
Other PFAS like PFOA, PFOS, PFHXS, and PFNA, which are the kind you would find used to coat the inside of a popcorn bag to keep the butter off the bag, are commonly found in human blood and have been linked to negative health outcomes in humans.
