I once worked with a guy who had previously worked for GCHQ doing something with cyphers/cryptography. He said he had never consumed more drugs in his life than during that period. They didn't care he took drugs as long as he was open about it and couldn't be black mailed through his use of drugs.

Interesting! Though GCHQ is UK, I'm not sure what the NSA is like. My impression so far here has been that they tend to hire people who live rather boring, quiet personal lives, since they're easier to vet.

I'm sure non-mainstream political views likely count against you more, though.
