I hear you but... nothing. We can't force drug users to not own drugs. If you have a gun, keep it, don't comply, rebel! There's no need to force it from you. Forceful removing comes up a lot but gun control isn't about eradication, like polio!
The point about gun control is that it's not owning the gun, it's _using_ the gun. There'd be additional penalties if you shot someone!
