What are the chances of getting my possession of a small amount of weed and drug paraphernalia charges dropped?

My friend and I were outside when he decided to whip out a bowl full of weed , then a police officer appeared and charged both of us with possession of a small amount of marijuana and drug paraphernalia . According to Pennsylvania law possession charges only apply if on your person. I was not found with anything on my person so I do not feel I should be charged.

That’s not what PA law says. A person does NOT have to actually possess drugs to be charged with possession of a controlled sustance. What county did this happen in?
