I have been put on probation and I enjoy smoking marijuana as a hobby and I am curious as to how much if any I can smoke and still pass urine drug screen I weigh about 140 and I have a fast metabolism and I am pretty active and I drink lots of fluids and I'm not sure if I even get drug tested but just in case I would like to know what I can get away with if anything cause I have heard the tests have to reach a certain amount of thc metabolites. What would you do?
