I was ticketed 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 roommates. Will this affect my probation in Washington? I'm really stressed about this because I could effect my schooling.

I am sure that others will answer your question. But, if I were you, I'd make sure that you speak with your probation officer as soon as possible about getting the ticket before he or she learns about it second hand.
