I have a family member who was recently kicked out of Coast Guard bootcamp. He's telling everyone it's becasue he recieved a ticket for underage drinking that he never told them about, and they ran a background check on him at bootcamp and found it. I don't know about the Coast Guard, but I know when I joined the Marines the only background check they performed was when I first joined, if you got arrested in between when you joined and when you left for bootcamp, the only way they would find out is if you tell them. To me it sounds like he failed his drug test upon arrival at bootcamp, but I'm not sure. I doubt even if they did find out about the ticket that it would be grounds for discharge. Any Coast Guard out there have some insight on this?
