Medical marijuana advocates want to see a number of changes made to the proposed measure.
Under the proposed rules, medical marijuana would be available only to patients with chronic medical conditions, such as HIV, cancer, glaucoma or multiple sclerosis.
The rules call for a total of 10 growing locations and five medical marijuana dispensaries.
The D.C. Department of Health will accept applications from individuals interested in running the cultivation centers and dispensaries. Gray will then assemble a panel to review those applications.
In a press release, the Gray administration says the rules are being published on an emergency basis to expedite the District's ability to meet the needs of residents who are suffering from serious illnesses.
The rules will take effect once the D.C. Council approves them or 90 days have passed.
