Arizona Department of Health Services rules divide Arizona into 126 areas called Community Health Analysis Areas (CHAA). The rules limit the number of Arizona medical marijuana dispensaries in a CHAA to ONE! The goal of ADHS Director Will Humble is to disperse the 125 dispensaries throughout Arizona to minimize the number of patients who will be able to grow their own marijuana because the patient does not live within 25 miles of a dispensary.
To view the CHAAs go to the Medical Marijuana Dispensary CHAA Map. You can zoom in and out or enter an address to determine the CHAA in which the address is located. If you click on a CHAA, the map will display the name of the CHAA, its ID number, 2000 population and 2010 population.
