apparently 2 weeks average.
BUZz UK Reviewed by BUZz UK on . Plz Help!! I was clean from marijuana since 3/12/04. Last weekend I took like 3 or 4 puffs off a blunt, 2 days in a row. I did the same last night. I know it is different for everyone, but how about someone whose system was totally clean for marijuana? For example, if I had to take a urine test on Tuesday, most likely i'd be dirty but a week from then? So basically I smoked twice , a week later smoked again. What is the likely time I will be dirty for? I am 5'8, 170 lbs. Metabloism could be better Rating: 5
