How do "abortion pills" work?

Can you provide a cite for Canada having more generic drug makers than the US ?

It seems Canada increasingly imports more pharmaceuticals from India; with 2021 imports worth about half a billion dollars.

Note: the USA has a US pharmacopoeia, UK has BP, India has IP, there is also a WHO Pharmacopoeia Internationalis online:

etc. On the other hand, there can’t be too many discrepancies, if any, can there?

Welp, looks like off-label medication abortions are going to be harder to come by in red states. And a lot of sick people who aren’t pregnant but need those drugs for their labeled use are going to get screwed too.
