Medical marijuana advocates were thrilled in 2009 when President Obama's Justice Department advised federal attorneys to avoid prosecuting patients who use medical marijuana in accordance with state laws, or their caregivers. Now, the thrill is gone. Deputy Attorney General James Cole has issued a new memorandum offering "guidance" on the earlier policy: All marijuana use and commerce is illegal under the Controlled Substance Act, Cole reiterated, and the new crop of state-sanctioned, large-scale marijuana warehouses and dispensaries are in federal crosshairs. Is this a flip-flop on pot?

Obama broke his word: There's obviously a "blatant contradiction" here, but Obama's trying to have it both ways, says Jacob Sullum in Texas' Odessa American. As late as last summer, his administration told Congress that state-approved pot purveyors could rest easy, as Obama had promised during his presidential run. This new "unacknowledged reversal" is a ploy to "get credit for tolerance" and for being tough on drugs.
