this isn't going to go through. I would wait until it hits the courts and ACTUALLY becomes illegal before buying anything. when substances like this become illegal it usually starts from a few states and then eventually becomes illegal nationwide. I wouldn't think anything of this. and the guy that got fined 500k is because he obviously added it not telling people and calling it something else.
I guarantee it'll happen, either sooner or later. Maybe not in the next month, but sometime in the next few years, for certain. Just look at recent history.
