Can I smoke

I have a drug test on april 12 which is 50 days from this saturday...I want to know if I will pass that test if I smoke on saturday? I am 5' 5" 115Lbs. I smoke 3-4/Wk. I have a fairly slow metabolism and subbing is not an option. I think the test will be a 20ng/ml but I dont know for sure. :rastasmoke:

Nobody can say with any certainty. I would say you would probably fine but how important is it to pass the drug test?
