I reside in Pennsylvania and I am 18 years old and I did have a clean record till now. So I was sitting my car in a parking lot with some friends and a cop rolled up and proceeded to question us. He asked to search the car, probable cause being he smelled marijuana. He seized around .5 grams of marijuana, a straight pipe with residue, and a grinder. Since everything belonged to me, I was the only person arrested and taken into custody. I was then taken to a hospital where blood was drawn to determine the concentration of THC in my system. I am being charged with DUI, possession of a small amount of marijuana, and one count of possession of paraphernalia. Needless to say, I have really no clue what's going to happen to me now, hence why I am posting this. I ask of anyone who has knowledge on a situation like this to please tell me what kind of punishment I can expect.
