This is the first I've heard of this but I believe you're telling the truth. It would explain the behavior of the doctors I've had contact with. One in particular seemed unusually please that I would try a nasal spray they recommended. I tried it once and put the bottle in my cabinet. In fact I have found that doctoring now days is more about collecting money than it is about finding the cause of the problem. To me it sounds like unethical behavior to reward doctors for prescribing certain medicines....like a kickback...
