Ok here is the deal. I work at a pharmacy, and someone has stolen some meds, now everyone is going to be drug tested. I have been smoking on a regular basis for a few months now. The last time I smoked was thursday night, and I smoked heavily. I may have a drug test on Monday and I am not sure what time so getting someone to piss for me or the fake piss will be tough to do, I am 5'8" 150 lbs with a pretty quick metabolism. I have niacin, but have read so many mixed results I am unsure of whether to trust the pills or not. Do any of you have any suggestions on how to pass my test ? Anything will be greatly appreciated, thanks.
