This is not terribly surprising. For good or for ill, recreational marijuana use never ceased to be illegal under federal law. And despite the various states passing laws legalizing it, there was that pesky little Supremacy Clause in the US Constitution.

It's been kinda annoying that people seemed to forget or ignore that. Hoping that the fed won't enforce a law was always risky. As we've recently seen, the political climate can shift suddenly and severely. And now people who think a law is a Good Thing that should be enforced have the power to do so.
