Jammy, Have your Lawyer check lab work. Depending on where you live they may just toss it once they dont find narcotics. I cant remember exact wording but its like a Felony/Narcotic presentation or somthing. I havent been a criminal in a few years so I cant really rememeber.. lol
I wouldnt worry too much, but that situation could put you on the radar. Like I said it depends what state and how hard the enforecement is.
Keep me posted
