My son was arrested in Maryland while traveling with some friends. Police found a bag of marijuana (less than a gram) in his backpack. He was arrested with a citation and released. His charge is did possess a controlled dangerous sub of schedule I marijuana less than 10 grams. Penalty is up to 90 days, 500.00 fine. My son is an 18 year old college student. Never any trouble til this. We live in NJ. Not sure what to do. Do we need an attorney? If so, How do we find the right attorney for this type of matter. How likely is he to actually serve time for this.
