It's funny, the Republican's generally represent themselves as a States Rights Party, but until Sessions came along, the AG's from both parties pretty much left the State's with legal cannabis alone. I believe they have the discretion to enforce, or not enforce the law as they choose. Sessions initially began to threaten States with the possibility of prosecution, and the Administration eased off a bit, but clearly his actions got the attention of Congress. I believe if he purely left it up to the State's and didn't stir the pot, it would have been less likely that Congress did anything.

Their probably still exist laws regulating everything from spitting on the street, to where you may, or may not tie up your horse. I suspect that many laws will never be taken off the books as long as no one attempts to enforce them, but when you do attempt to enforce an unpopular law, it gets attention.

I frankly believe that had Sessions taken a State legal cannabis operation to court, he'd have been hard pressed to find a jury that would agree with him, even though it clearly was illegal based on Federal law. If as some believe he will be replaced with someone who also opposes legalizing cannabis, the pot will continue to be stirred until Congress takes actions. I know the President has spoken about taking action himself, but I'm uncertain how far he actually can go. I'm not even certain if Congress is necessary if cannabis were reclassified, but it may still be in the case of recreational uses if it's not covered by the way it's classified. Legislation which simply left it up to the States could be the easiest thing to do, it should make it clear that banks could deal with companies that are operating legally in the State. I suspect that before you know it, over 40 States will have in some way legalized cannabis, and over time most will move to legalizing it recreationally.
