hey brandon do you know how pain management doctor testing works? i am on pain management but tend to smoke once in while. do you know if they use the imunoassay testing or the gc/ms testing? trying to figure out a way to be able to smoke once in while and still pass my random test that is done only once a year. what about freezing ones own urine then letting it thaw and get to 98.6 degrees for office visit? anyone tried that?
