DT next week.. Will I pass?

I am a casual smoker, usually only on the weekends. I found out I have a drug test sometime next week. I quit smoking on the Dec 5. I'm a 160 lb/5'7/F.. I'm not in great shape.. but not terrible either... i'm working out as much as possible with finals this week... But I need some opinions.. My first new job depends on it! :confused: Is using someone else's urine necessary? Is it too much of a risk? I'm getting tested by firstlabs.. anybody know anything about them? Thanks for the help

just exercise a lot, drink lots of water, cranberry juice and green tea (like arizona green tea) and take like 2-3 niacin b12 pills each day between now and then. this worked for my friend a couple of times, he had last smoked bout 3-4 days before the test. remember dont use the begginin or end of ur piss stream, use the middle. good luck man!
