It’s perfectly fine so long as none of the coating gets in your body, but given you’re making food with it, there’s a high chance it will.

If it get’s too hot it will off gas, if it gets scratched with something harder than it (like a metal spatula, or salt grains) it will flake off. So you should use plastic or wood utensils when cooking in one, and the black plastic utensils have their own issues with often being made from recycled plastics that have fire retardants mixed in, which can leach out.

You can be safe with them but it requires you be careful and deliberate with use. Personally, I think it’s easier just to use something else, even if that means taking the time to learn about how to use them well.
