I am a captain in the military, active duty and will tell you that as long as your smart about it and not a Soldier who ****s off / gets in trouble you will be fine. The piss tests look for weed/coke/x and other stuff like that. As long as you are not jacked out of your uniform no one will say anything to you. Just be smart about it and go to the gym off duty and dont tell your brothers in the barracks because that shit gets back to us. BTW what unit / name etc? jk...enjoy
