i would say im pretty damn sure that you will pass the test. Generally speaking, a month is a good amount no matter if you are a heavy smoker or not. I dont know if you have been doing this, but as you know, your stores are located in your fat cells. Working out, or just sweating/drinking water in general is the best natural way of trying to get clean. Even if you have been slightly inactive over the 33 days, i would still think you should be fine. I can generally get myself clean in 7-10 days tops, but that is with every day hard workout, large amounts of water consumption, and having a seriously heavy duty metabolism. You should be fine
