If you're wondering how long marijuana stays in your system after smoking, it depends on how often you smoke. Light users -- those who smoke pot once in a while -- will have a negative drug screen after a marijuana-free week. Heavy users -- sometimes called "stoners" -- may continue testing positive for a month after last smoking pot.
