Peeing for employment

I came back from a job interview a couple of hours ago and they said I got the job dependent on whether or not I passed a drug test. I understand that it's important to make sure your employee's don't do drugs, but I still insist that smoking pot isn't bad for you. I took a couple hits the other night and aside from that I've taken at most 4 draws off a pipe maybe 2 times in the past month. Am I a criminal? Just because I smoke and relax occasionally? I believe there are faaar worse things that I could be doing than smoking some herb every once and awhile. I don't want people to respond to this thread with "yeah pot rulez" or "legalize!".
I really just need help passing this drug test. How would I go about exchanging my urine for someone else's? OR Tell me what flushes out your system best. Simple math, I smoked Wednesday, my pee will be in a cup by 11:30 tomorrow morning.

Errr, heavy drinking of beer or milk but i think you are screwed. Also cheating is hard because the urine still needs to be warm. You could fill a condom with piss and take it with you + a needle. In your case bribing is best. Ask yourself the question if you would take the money if you were in his place. Or suck dick.

Buy "fruit pectin" at a supermarket.  In the morning, take a spoonful of pectin with a glass of water and a B vitamin.
