Thanks, that explains a lot.

I still wonder why the law is that way though. As drugs go, marijuana is probably the least worrying when it comes to gun possession. As it makes people docile and relaxed, it will help de-escalate conflicts.

As opposed to coke which makes people pumped up or even the fully legal alcohol...

It sounds like federal law should catch up to reality. Though as a European I am not in favor of widespread gun use anyway but that's another discussion.
