If you've got a prescription you're covered, it don't report as positive.
Like time release morphine
A bear walks into a bar and orders a beer. The bartender says, sorry, but we don't serve bears here.
The bear points at a woman sitting at the bar and says, if you don't serve me I'll eat her. The bartender shrugs and says, doesn't matter.
So the bear eats the woman. He points at the bartender and says, serve me NOW!.
The bartender says, trembling, I can't serve you now for sure, we can't serve you if you're on drugs.
The bear, surprised, says I'm not on drugs! The bartender looks him straight in the eye and says:
That was a bar-bitch-you-ate.
:-) I'm here all week.
