You get better replies when you do the whole story on one post.
It doesn't matter if you say it is not yours
Possession makes it yours. The only way you could possibly get out of that is IF someone steps up and says it was theirs and you had no idea they left it in the car. I doubt any of your friends would be willing to admit to it being theirs.
Even then they can still charge and convict you for it.
You told the officer up front though so there is no denying your possessing it.
At the very least they would reduce it to a summary offense and give you around a $250. Fine for each count, but with the second charge you probably won't get off so easy.
It depends on the quanity too. I don't do drugs so I am not sure on the technical details.
