PORTLAND, Maine (AP) — Maine marijuana enthusiasts will probably be able to purchase their preferred products in retail stores by March 2020 after years of waiting.

Voters approved legal adult use marijuana at the polls in November 2016, and the road to legal sales has been long and bumpy.

The state's Office of Marijuana Policy says a key act passed by the Legislature is now in effect, and that means the office is in a position to complete final adoption of Maine's marijuana rules.

The act made tweaks to Maine's Marijuana Legalization Act that were necessary for the marijuana office to adopt the rules, which it is expected to do within two months.

That means it will probably be able to accept applications for retail marijuana sales by the end of 2019.
