Just one other thing to remember, a drug possession charge will result in a 6 month suspension of your driving privilege in PA. The smart move would be to seek a court appointed attorney or talk to the local bar about legal aid. (reduced attorney fees for people who's income qualify)

You do not want a drug possession charge on your record, especially if they charge you as an adult. It will close a lot of doors later in life. This is NOT an easy charge to fight so get your parents involved ASAP!
