Medical marijuana advocates gathered in front of the D.C. Department of Health yesterday to demand that the city’s program be implemented more quickly.

It was two years ago today that the D.C. Council gave approval to the city’s medical marijuana program—and that was 12 years after D.C. voters had overwhelmingly voted to legalize the use of marijuana for medicinal purposes. But today patients still can’t get medical marijuana, and some advocates worry that it may not be until the end of the year until they can.

Medical marijuana advocates gathered in front of the D.C. Department of Health yesterday to protest what they say is the city’s slow pace in implementing the long-awaited program. While licenses have been handed out for six cultivation centers and ANCs are currently weighing proposals for four dispensaries, the advocates said that the city hasn’t started outreach with local doctors—some of whom have said that they’d be nervous to recommend medical marijuana to patients—nor has it started registering patients.

Medical marijuana is expected to be available by the end of the year, but even then there are concerns over whether there will be enough for qualifying patients. While an initial D.C. census estimated that 800 patients would qualify in the first year of the program, advocates say the number could be significantly higher. Additionally, the number of approved cultivation centers and dispensaries is under what the program’s rules envision, leading many to express concerns that marijuana will either be unavailable or prohibitively expensive.
