Here is my info, you can ping if you want. Not that it will do much good, but anyway...
Back when I was in college (late 1980’s), a buddy (white male) interviewed for a DoD job and was turned down immediately upon confessing to having used recreational drugs. I did work for DoD for a while, and met a woman who told me she used them and still got a clearance. There may be some affirmative action in the investigations — obviously two cases don’t prove anything.
