Yes, of course asbestos has been banned in the US from friction materials. However, some members have reported getting some types of PBR pads with a warning on the box that they contain asbestos. PBR is not an OEM company and they are not manufactured in the US. I would not use any pads that contained asbestos on my car. Most of the PBR pads are asbestos free, but a select few might not be, I would be sure before I used them.
I refer you to the following thread. If you scroll down a little you will see a discussion on some PBR pads containing asbestos.

That is just my 2 cents. You are, of course, free to use whatever you want.
