2 words : STATES RIGHTS
http://blogs.ajc.com/bob-barr-blog/...a-welcome-change/?cxntfid=blogs_bob_barr_blogOn October 19th, in a partial but welcome reversal of that Bush-era policy, the Department of Justice issued new guidelines for United States Attorneys in those states (California and 14 others) that have medicinal marijuana laws on the books. Henceforth, so long as individuals in those states are using marijuana for medical purposes and are in full compliance with the laws of their state, federal prosecutors are not to pursue prosecution of those people. The Justice Department memo did provide that if any number of other factors were present (such as violence, sales to minors, ties to other criminal actions, and so forth), prosecution by the feds might be warranted.
