I have a drug test this Monday (October 25). I haven't done any other drugs, and the last time I used marijuana was Wednesday October 6. I used to use marijuana once in a while; there was no pattern to my use. It would be anywhere from once every two weeks to three times a week. I am 160 lbs, I do lots of heavy exercise all the time because I am involved in mixed martial arts, and I have been trying to drink lots of fluids.

What are my chances of failing this drug test/what can I do to pass it? This job is super important to me and I need to pass!
