(Washington Examiner) — D.C. Mayor Vince Gray officially proposed on Thursday the rules to govern the dispensing and growing the drug in the District. The mayor can’t move forward with the plans until either the D.C. Council gives its approval or 90 days have passed since Gray’s proposal. Once one of those has happened, Gray can assemble the five-member panel that will review and approve the applications for the 10 growing centers and five dispensaries the rules call for. The D.C. Department of Health will then run the medical marijuana system. Gray said Thursday that he hopes Congress doesn’t try to kill the city’s marijuana program.
