Phoenix New Times:  “A new rule on foster parenting released by the Arizona Department of Child Safety still discriminates against cannabis patients, but it defies federal authorities in approving cannabis extracts.  The rule codifies a September decision about a possible foster-care license for a woman who treats her adopted 12-year-old son’s self-injuring behavior with cannabidiol (CBD).  Phoenix New Times received a copy of the ruling last week after a public-records request.”
