Reuters:  “State-run medical marijuana dispensaries will not be coming to Rhode Island after Governor Lincoln Chafee scrapped the plan for fear it was illegal under federal law.  Chafee, who had earlier vowed support for the measure, said he decided the state’s planned dispensaries could violate superseding federal law and become a target of federal law enforcement efforts.”

This is probably the tactic Arizona Governor Jan Brewer will take to prevent medical marijuana dispensaries in Arizona after her Arizona vs. United States lawsuit gets dismissed by the federal court.
