I have a story.
When I was 17 I wanted to join the Air National Guard. Mainly for the money benefits, but I needed to do something with my life to stay out of
trouble, and from what I learned about my local Guard unit, they were a combat communications squad and the training I learned there would be a good
start on a good "civilian job".
By the time I was 17 I had around 32 misdeamoners and 1 felony on my juvenile record, no adult charges. All minor charges, the felony being theft by
recieving.
So I contacted a recruiter, and went through the basic questions and information process. I at a point was going to go to take some physical and I
think some other tests, including drug tests.
My recruited under no certain terms informed me that marijuana in your system was not a disqualifying drug, but other drugs would disqualify for years
or months depending on the drug.
Upon arriving at the center for tests, the absolute first thing they tell us is if you have marijuana in your system your wasting your time, 6 months
you are disqualified, coc aine 1 year, etc....
I immediately was like WTF?!?! Why would my recruiter allow me to come here, knowing that I was going to fail, I had informed him that I regularly
smoked marijuana, and if I needed to stop to clear my system out it would be no problem.
So of course my tests come up positive and bam, disqualified.
Somehow, my recruiter worked a loophole where I could go to another facility for the tests, and my first test would be as though it never happened.
Knowing from my first experience, I stopped smoking and went on to pass the test.
Ended up being sworn in, raised my hand all that jazz and was now an "official" member of the Arkansas Air National Guard.
Or was I?
About 2-3 weeks after my swearing in (I also got a nice little coffee mug) I recieved a call from my recruiter, telling me there was "some kind of
problem with my drug test" and I needed to come in and speak to him, and the Colonel.
Apparently "further" tests on my already passed drug test found "something" and I was being given the boot. They kindly explained that since I had
just gotten in, no paperwork had really went through, I wasn't officially in the AANG, there would be no discharge, and have nice day. Oh, and I
couldn't apply for ANY branch of the Air Force.
I was like

I couldn't understand it, and honestly still can't make since of it. My best guess, was that they got access to my juvenile
records, deemed me as a troublemaker or someone who would be a hardhead and figured I'd be better suited in the Army or Marines.
The OP explaining that even a juvenile felony counts against you, makes that seem more likely.
