How long does it take for pot to clear your sysyem?

Well first off you shouldn't be smoking pot ;) but if you decide to give in depending on how long you smoke any where from two weeks to a month. There's math behind it ... Smoke once wait 2 weeks. anymore then that you need to wait a month from the last time you smoked. However im 18 5 foot 11 weigh 150 lbs and i passed a test a week after smoking a eigth... So happy blazzin stay high n fly
