The bong and pot is a non issue ... Raven vs State of Alaska. Small amounts of pot in your home for personal use is legal and has been since 1975. The Trooper had no buisness starting this confrontation over the pot.

In 1975, in Ravin v. State, the Alaska Supreme Court held that the Alaska Constitution�s right to privacy protects an adult�s ability to use and possess a small amount of marijuana in the home for personal use. The Alaska Supreme Court thereby became the first�and remains the only�state or federal court to announce a constitutional privacy right that protects some level of marijuana use and possession.
