Several US states have implemented adult ID requirements, in a way that seems less free than the past wild west.

That's political pandering in the face of a macro trend going in the other direction. Ain't no different than NY tightening up its gun laws after getting slapped in Bruen(sp?).

You see this behavior among the hold outs every time. Southern legislatures passed all sorts of dumb laws at the end of the jim crow era. I bet sure a few states will pass absurd laws as weed continues to get legalized.
