I personally don't agree with the interpretation that drug control is a federal jurisdiction, but that is the status quo. Your second statement is true: Federal law DOES apply across all states. State law does not nullify or override this. There was a damn big bloody war over that question. Allowed does not mean legal. That's why it is still illegal, but unenforced, in several states. A state CANNOT legalize a controlled substance. To trust lax federal enforcement + state "legalization" is not a wise move. But practical. And besides, security clearances come from the Feds not the states, so who's laws do you think they go by?
