yea, I'm not sure what would happen if you failed drug test in the military. I'm sure that they would do more than just 'fire' you. I hate to say it but I would stop smoking if I were you. Even if you don't like it, knowing that you were discharged form the military for getting high would probably haunt you for the rest of your life. The last thing we need is someone else blamming the way they ended up on weed. Good luck man.
