I am filling out the paper work to obtain a secret security clearance and have a question.

I was arrested in 2003 in NYC and charged with disorderly conduct and criminal mischief. both misdemeanors and i was 18 at the time however it was placed on my minor record as a minor was charged with me.

So the question I have is when filling out the clearance form do I need to mention this since it was on my minor record?

I have also used marijuana during my party days at college which was two years ago.

also would these two things combined hurt my chances of obtaining a clearance?

I appreciate your help!
