I haven't taken the opportunity to bitch about this yet, so I'll do that now - the TL;DR version: drugs are bad, don't do drugs, m'kay?
The way I understand it: at the time my NGB package and waiver request were under review (Sep 2013), there was an inconsistency between ANG and USAF policy. ANG said < 12x is waiverable and USAF said > 1x is DQing. My package was rejected (sts) due to confusion over the inconsistent policy, and my SQ/CC reattacked. The policies were brought into agreement and my self-admitted > 1x DQ'd me.
Not sure if my experience is common or just a one-off. The final explanation I was given for my DQ was that marijuana experimentation > 1x, even if it was in high school over 10 years prior to commissioning, was behavior inconsistent with serving as an officer. 1x is waiverable; anything beyond that is DQing.
I was fed several lines by officers and recruiters toward the end of the years-long process of applying, interviewing, enlisting, waiting around, FC1, TS, waiting around, DQ, waiting around and separation: 1) I probably should have lied about it from the start (poor SA on my part), 2) I never should have been interviewed by a single fighter squadron (or 5) based on my honest reply to the prior use question, 3) I should stick to getting f*#&ed up on alcohol, 4) at least I have a TS and 5) timing/luck is everything.
I honestly thought I could get the kill, but despite the ass pain, I'm thankful I wasn't waved off before making a pass at getting hired. I met some truly kick ass, amazing people and had some unforgettable experiences.
But... I never got the chance to take the controls of a USAF aircraft, so I lost.
Best of luck, and thanks to those who offered advice along the way
