Most likely tommorow I will have a urinalysis test after my interview. I stopped smoking just about 3 weeks ago and before that I smoked heavily on and off for about a month if that. I drank like 3 big jugs of cranberry juice and I was wondering if that could have done the trick as far as cleaning up my system. I am 5'11" and 230 lbs. I know that your weight has a little to do with how long it stays in the system.
