East Valley Tribune:  “State Health Director Will Humble refused Thursday to expand the conditions for which marijuana can be legally recommended. . . . Humble’s decision disappointed Suzanne Sisley. She is a physician with the Telemedicine Program at the UA College of Medicine and a specialist in internal medicine and psychiatry.  She said that, despite the lack of formal full-blown scientific studies, she believes marijuana works. . . .Sisley said, though, the decision comes as no real surprise.  She said that Humble, in demanding evidence from scientifically backed peer-reviewed studies, essentially set the requests to expand the medical marijuana program up for rejection. That’s because the National Institute for Drug Abuse, which controls the only legal supply of marijuana for medical research has consistently refused to give the go-ahead for the kind of studies Humble said he needs.”

“I’ll concede that the clinical-trial type of research is controlled by NIDA (National Institute on Drug Abuse) and they are pretty strict when it comes to clinical trials, when it comes to the use of testing medical marijuana.  But there are all kinds of studies that can be conducted that don’t need NIDA approval.”
