Background check

I had got a job offer from Sears and they sent me some info for a drug test & background check. I'm not worried about the drug test but the background check I'm a little worried because I have a misdemeanor for CDS/marijuana from last summer. I was not convicted & I got a nolle prosequi, meaning my charges were dropped & thrown out. My case never went to trial and I didn't have to pay a fine neither. But my expungement is still pending. I told them about it and they were completely cool with it after I told them about they situation and how I was wrongfully locked up because I didn't have marijuana on me but one of the people I was with did. The damn police locked all of us up anyway because in his words it was all about "number", meaning his greedy *** wanted to make a quota. Anyway I'm so worried about this because I know it would show up on my background check with HireRight, but will it affect my chances of getting the job?

soo....how did it all turn out?
