it is in your possession so you are committing a crime. If it were me I'd call the po-po's and have them get rid of it so you don't get in trouble.
The punk criminal kid is committing a crime and making you an accessory by using your property without permission, so I'd nail him to the wall.

But that's just me. I don't like drug dealers or people who do things that could get me thrown in jail.
