If you get caught in SanBerndino they will confiscate even if you have a license, I was riding with one of my homies who has his license and we got pulled over (i had nothing on me nor do i have a license) he searched us because there was a "drug dealers scale" on my console, which was actually just a electronic address book but he had to have some excuse so he used that one but anyways he found 3 grams on my buddy which was even in the bag from CC along with his license -- he gave us the party-line speech about pot "which causes thousands of teen driving accidents every year" then took the weed giving us a so called warning. he gave me a fix-it-ticket for not having a rear-view mirror (it got yanked off by accident)

I know it is unlikely to get into trouble if your licensed in cali but it can happen.
