Arizona is the Wild West of medical-marijuana testing, with no more government oversight of product safety in dispensaries than there was in 1800s-era drugstores.
Yet with concern about contaminated legal cannabis rising in recent months with reports of recalls and new state laws that require testing of marijuana products, should the state adopt its own quality standards?
Will Humble, who served as Arizona Department of Health Services director from 2009 to 2015, said he doesn't think the state needs to enforce purity standards for medical marijuana sold at dispensaries, at least for now.
"Until I was to see survey data of illness and injury that was compelling, I would say where's the public health mandate to take action?" Humble said.
