Good. What's important is whether you are impaired, not whether you ever consume impairing substances.<p>If marijuana users aren't ever allowed guns why in the world do we permit alcohol users guns? I'd be much more worried about a drunk with a gun than a stoned person with a gun.
I wonder how this interacts with, or not, getting charged with a crime and possessing cannabis and a gun at the same time. It seems like they all really trump up the other charges federally, even when the crime doesn't involve either.
