JUNEAU, Alaska — Smoking, growing and possessing marijuana becomes legal in America’s wildest state Tuesday, thanks to a voter initiative aimed at clearing away 40 years of conflicting laws and court rulings.

Making Alaska the third state to legalize recreational marijuana was the goal of a coalition including libertarians, rugged individualists and small-government Republicans who prize the privacy rights enshrined in the state’s constitution.

But when they voted 53-47 percent last November to legalize marijuana use by adults in private places, they left many of the details to lawmakers and regulators to sort out.

Meanwhile, Alaska Native leaders worry that legalization will bring new temptations to communities already confronting high rates of drug and alcohol abuse, domestic violence and suicide.
