Tucson Weekly:  “While marijuana advocates look to legalize in Arizona, concerns remain about medical marijuana program.  When Arizona voters approved medical marijuana in 2010, the traditionally conservative state did so tentatively. . . . State officials now call Arizona’s system a model for other states, and members of the pro-legalization campaign deem the system a big success. . . . However, opponents of marijuana legalization said the system is ‘cloaked in secrecy’ and questioned whether Arizona is a model state, pointing to factors like its high number of medical marijuana cardholders. They also raise concerns about a lack of transparency and question whether the system has hindered drug cartels as supporters claimed it would.”
