Arizona Republic:  “The top lawyers for the state and county, strong opponents of Arizona’s medical-marijuana laws, will argue in court today that federal drug laws pre-empt the voter-approved law.  Attorneys arguing on behalf of White Mountain Health Center of Sun City, meanwhile, charge that state law does not require anyone to violate federal laws by issuing permits for medical-marijuana activities since the state has decriminalized those acts. In their lawsuit, they also allege that Maricopa County illegally rejected the center’s registration certificate, which is among the state requirements to become a medical-marijuana dispensary applicant.  At stake is the future of medical marijuana in Arizona.”
