I am from Pennsylvania but while I was in Maryland I was charged with a possession and paraphanelia charge. We were leaving the hotel about to go home when some police officers came over to the vehicle. They said they smelled marijuana inside the car and had the right to search the vehicle. While searching the vehicle they found a stem from marijuana with a bud on it no bigger than 0.2 and a bowl/pipe. They asked whos pipe it was and I admitted to it being mine and my friend was also arrested because it was his car and they found the stem in his car. They never told us our rights and I didn't even have any photo i.d. alll I had was my social security card. After being cuffed and being brought to the back of the police van i was then asked if i was 18. in the report it says they identified my with my pennsylvania drivers license (which doesn't exist because i dont have one or even a state i.d.) I then spent the night in jail and have court in october. I was wondering if I could go to jail for having that possession charge and this paraphanelia charge, this is my first offense for anything as a juvenile or as an adult and I've never been on probation or anything what should i expect and what are my options?

also, there was no drug test performed and they did not tell us why we were being arrested the only thing they did was shine a light in my eye while it was closed and they said there was thc in my system because my eyes moved while the light was over them i guess. but my friend who was high passed this test so idk how it works
