Anyone have any experience with this?

I was just offered an internship to BIT Systems to help with satelite dynamics and controls pending gov't clearance. I was given an 8 page document where I am to detail my entire life. They have a section for everything including drug use. At the end, i get a polygraph test im told and if i fail that... im done. And Ill probably need gov't clearance to work at any job in my field most likely.

I wanna know if they care that i've done drugs or just if im honest about it.

If it helps, i know im not addicted to pot or alcohol since i've gone a semester without drinking alcohol for my diet and pot just isnt addicting. Im much more addicted to food than any drug. I've tried coke and shrooms and have had the intention of trying acid.

I'm afraid this won't look good on paper and that i might overly spin it during the polygraph and fail.
