I agree. Perscription drugs are much better off left in the bottle.
From what I can tell, in your case the fact that you RAN FROM THE COPS magnified the situation. I mean, the police are thinking you ran for a reason right? Could the reason have been the unidentified pill on your person?
If it was a routine traffic stop and the cop noticed a pill in the center console it usually isn't going to turn into anything. I have OTC meds and supplements all over my gym bag. No cop is going to suspect/book me on charges for that.
