Drew has some extremely skewed ethics. Any ethical practitioner would have referred many of these individuals to a higher, more appropriate level of care than what he was able to offer on this show. Regardless of if these people were paid by producers he was treating them as a practitioner in that facility. That is unethical of him to do that knowing these people are not placed appropriately.
They deserved to be placed appropriately. It would be like me taking a suicidal patient is saying well since the producers paid for this you're only going to get the 3 day hospital stay instead of what you probably will need. It's unethical.
