Jeez....Um find a new girlfriend? Or watch the movie Harsh Times with Christian Bale and check out how he tries to pass his drug test...not for the faint hearted. I don't want to describe it here.

Or get a urine sample from someone you know that doesn't smoke (and is obviously willing to give you their urine.) and use that for the test.

Or try and put it off for a couple of weeks and not smoke and maybe you will test negative.
