ST. PAUL — Gov. Mark Dayton on Thursday appointed 16 members to a task force that will study the impact of the state’s new medical marijuana law.

The governor’s appointees to the Task Force on Medical Cannabis Therapeutic Research range from law enforcement officials to people who treat substance abuse to potential patients and their parents. They’re charged with overseeing the rollout of Minnesota’s program and evaluating access to the drug, the quality of medication and its impact on law enforcement and the medical community.

Patients are expected to be able to get medical marijuana starting July 1, 2015.

The Legislature passed a bill that gave Minnesota one of the nation’s strictest such laws. Patients can only use a pill, liquid or vaporized form of the drug, and only those who suffer from eight illnesses including cancer, HIV/AIDS and glaucoma will qualify for the program.

That bill also created the 23-member task force, which will also include of two members from each the House and Senate and the commissioners of the departments of Health, Human Services and Public Safety.
