Not a crock at all. To provide just one example, I'm a caregiver (the non MMJ kind) for an elderly blind man. Another condition prevents him from walking. Before he took my advice and got on the registry, he was having a terrible time with unreliable dealers and poor quality control. He was being ripped off. It wasn't because he was "not trying" but because he is a homebound disabled man in a rural part of the state. Centers have been a godsend for him, finally providing reliable access to reliable medicine at much lower cost than he was paying before. He's also discovered some hash and extracts that ease his back.
