I'm an off and on smoker. I will smoke for about a week straight then not have any for a few months. Currently I haven't smoked in 2 months. And I took about 3-4 hits a week ago. How long will it stay in my system? I have to take a drug test for the medical program that I intend to sign up for. I'm not sure if it's a urine or hair test. How will I wager on both?
