Bad news: Todays needles are coated in PFAS to make punctions more painless.

[–] SuperIce@lemmy.world 19 points 1 day ago (2 children)

That's kinda misleading though. Large molecule PFAS are harmless to us (Teflon for example). It's the small molecule PFAS are dangerous and those aren't really used for any kind of non-stick surfaces.

They're part of the waste of producing non-stick coatings. So you aren't exposed to them by the needle or your Teflon frying pan or the Teflon tape in your plumbing, you're exposed to them by the Teflon plant dumping their waste in the river, legally or otherwise

Which kinda PFAS do they use for hydrophobic coatings

I've never really looked into this, do you have any good sources you recommend looking at?

Uuugh I don’t want to switch to daily gel or patches, it’s such a pain in the ass.

Unfortunately no. Afaik even regular exposition is (for now) considered relatively harmless, with medical professionals bearing the highest risk.

I thought the injection would be the one that is a pain in the ass πŸ€”
