Tucson Weekly:  “It’s going to get a lot easier for medical marijuana dispensaries in Tucson to expand thanks to three zoning amendments the City Council passed Tuesday evening.  Here’s the good news:  Outdoor cultivation of medical weed is now allowed in industrial zones in accordance with state law. The Arizona Medical Marijuana Act says that outdoor growing is good to go only if the area is surrounded by 10-foot walls made of metal, concrete or stone that prevent outsiders from seeing the marijuana plants.”
