To tell you the honest truth, it depends soley on how much you smoke. No matter what, Marijuana can stay in your hair for up to 4 years.. If you have a blood test, Marijuana can stay in your blood stream for up to 1 month.. If you have a piss test, Marijuana can stay in your urine for up to 2 weeks.. These are based off of you being a habitual smoker. Say you smoke once a month? Marijuana can pass through your urine in as little as 5 days. Add a little bit of exercise to that and drink some water, and it can leave your system in 3 days. The THC in Marijuana is obsorbed in your fat cells, if you are fairly active, you really don't have anything to worry about.
