On May 9, 2011, the American Civil Liberties Union (ACLU) called on U.S. Attorney General Eric Holder to make clear that the Department of Justice will not prosecute people who comply with state medical marihuana laws.  Concerned about recent letters that threaten state employees and state licensed providers of medical marihuana, the ACLU is seeking clear guidance that state laws will be respected.  According to the ACLU's letter, the Department of Justice's attempt to dissuade states from enacting and implementing medical marijuana laws is an abuse of its role as an impartial prosecutor and undermines the legislative process of various sovereign states.  The ACLU's letter may be viewed here.
