8 states have already legalized recreational marijuana.

No they haven't, they just voted to ignore Federal law, they didn't change the law.

This is step that, once taken, there is no way back.

From a procedural standpoint, you're wrong - legislatures repeal laws all the time.

From a practical standpoint, the step has already been taken ... 8 states have already legalized recreational marijuana.

No they haven't, they just voted to ignore Federal law, they didn't change the law.

My point remains.
