BISMARCK, N.D. (AP) — North Dakota’s Health Department has chosen operators for medical marijuana dispensaries in Devils Lake, Dickinson, Jamestown and Minot.

Those operators must still go through the registration process and meet all state requirements.

The Health Department earlier named operators for dispensaries in Fargo, Grand Forks, Bismarck and Williston. The Fargo facility opened for business on March 1.

State Medical Marijuana Division Director Jason Wahl says all eight dispensaries are expected to be operating by the end of the year.

North Dakota voters approved the drug in November 2016. The Health Department has been working on the system since lawmakers crafted initial rules in early 2017. The rules are being fine-tuned during the current legislative session.

The state expects as many as 4,000 residents will legally be using medical marijuana by summer 2021.
