A "State's (District's) Rights" Issue

Looks like the medical Cannabis issues are encroaching upon Pennsylvania Avenue.  The pressure is on in D.C. to legalize medical pot right next door to the halls of congress from whence cometh the anti-pot laws to eclipse all other pot laws.  D.C. wants to legalize medical Marijuana but is moving at a snail's pace because the Department of Justice is making louder noises about enforcement.  From a DCist article:

While the rollout of the program has indeed been slow -- initial rules regulating the program were first published last August, and the city hinted that medical marijuana would be available by mid-2011 -- city officials are asking for patience as they navigate the minefield of potential congressional and federal intervention.

Representatives from agencies that would oversee the program met two weeks ago in the Wilson Building to discuss whether the city's program as currently structured would trigger any federal response, especially in light of the recent DOJ memo that seemed to end the Obama administration's permissive attitude towards state-led medical marijuana programs.

Sounds like this could become a deciding moment in the State's (District's?) Rights battle over medical Marijuana.
