While standing in a parking lot with 3 of my friends a cop pulled up and immediately asked for ID's without question. He then called for 2 other officers to come. On us we had around 1.5g or pot. This was not mine but it was in my pocket because I was looking at it when he came up. When asked if we had anything illegal we gave it up, and I was charged with the possession and no one else got anything. What penalties am I looking at? Anyway around this?
