The Alaska Supreme Court ruled in the 1975 case Ravin v. State that the state constitution's right to privacy protected the ability to use and possess a small amount (defined as less than four ounces, according to law professor Jason Brandeis) of marijuana at home for personal use.

Although there has been opposition to the law, the Washington Post reported in 2014 that courts in the Frontier State have generally upheld the idea that constitutional privacy protects those in Alaska who personally possess, use, or cultivate pot.

In 2015, Alaska officially decriminalized marijuana with the approval of Ballot Measure 2, which allows anyone in the state who is 21 and older "to possess, use, show, buy, transport, or grow set amounts" of it. However, the law bans people from using it in public.
