PORTLAND, Maine (AP)   Maine’s proposed rules about the sale of marijuana for recreational use would for the first two years limit licenses to residents of the state.

The state released its long-awaited draft rules about the recreational marijuana program late Monday. Residents voted in favor of legalizing marijuana in 2016, but crafting the rules has been a long and sometimes contentious process.

The draft states Maine will only give licenses to grow and sell marijuana to people who have lived in the Pine Tree State and filed income tax returns there for four years. That standard would apply until June 2021.

The draft rules are subject to public comment and face state approvals.

Maine already has a long-established medical marijuana program. It’s also currently legal to grow marijuana for personal recreational use there.
