Just wondering has anyone else wondered why we have to pay for ketamine trials? I was always under the assumption that trials where payed for by the foundation donations or the universities $, goverment funds. NIH trials are payed for. We are the ones taking the risks. I realize we have to pay for the staff caring for us but since it is trials I just don't get it. How do they come up with whatever the cost is like 2500./day. I would somehow find a way to pay out of pocket if I need too, but I was just wondering if anyone knows why a trial that is not approved yet, and is at our risk, costs as much out of pocket as it does. It does not cost 2500. to stay one day in the hospital for just nursing care. What's the deal??
