I just finished 20 years. Was a command DAPA and AAS are not part of the testing regiment unless specifically requested, which I never saw done. I saw numerous guys never pop while using, but saw 2 guys get thrown out for using AAS because they ran their mouths and eventually 100+ people knew. After that a health & comforth berthing inspection was done and their gear was found.
So, you shouldn't get caught if you keep it a tight lipped secret.
