you really should be fine if you dont over do it and give youself atleast 3weeks before your test, and work out a bit, and you can stop a few days before the test. You should be fine. I passed a DD and i smoked about a bowl or two a day for two weeks and stop 12days before and passed and i didnt workout much and i weighed 140 and 6feet tall. The general rule of thumb for testing positive is between 1-30days after smoking, 30days if your a heavy smoker, so you really should be fine. You should post some more details of your smoking habits you will be doing and stuff in the drug testing forum for better advice from killerweed or fakerealboobs.
