how tall are you. if your 2 foot 2 and 125 (probably 2 foot 2 wide in that case) it will take probably 5 or more days. If your slim and have a high matabolism then it could be un detectable by drug test the next day. I would say 3 and your good if you havent smoked in 3 or 4 months. If you smoke more often it will take longer for all the metabolites to be flushed out and could take up near a month.
