I was given a traffic ticket for possession of marijuana in California and I am on probation in the state of Washington. All I had in the car was a little nug not even worth 5 dollars and it wasn't even mine, it was my roomates. Will this affect my probation in Washington? I'm really stressed about this because I could effect my schooling. I wasn't high and I don't smoke, the car smelled like smoke because my roomates smoke in it prior to me picking up the vehicle. Can someone give me some advice?

Yep, call the probation officer and explain it all to him, you violated probation now in several ways, being around those smoking pots, so you associated with the wrong people, next you had it in the car ( if it is in the car, even if it belongs to someone else, you can be charged) so possession.

So most likely if your probation is not drug related, you will be OK, but get with them ASAP, don't let them find out by other state notifing them
