OECD definition

> any chemical with at least a perfluorinated methyl group (–CF3) or a perfluorinated methylene group (–CF2–) is a PFAS

I don’t think that includes any of those, and Xanax is not fluorinated at all. You might have been thinking of Prozac, which I believe does meet those criteria.

It is a broad category with competing definitions, some of which are even broader, though, yes.
