That would be an apt description! I met one Dr. Facilier who took very little care of the people that trusted him, used the spotlight to play very inadequate songs and feel like a rockstar while people were tripping their guts out. Only to hear him later talk in a low voice to the guy that owned the place if next time they could pack the place even more. Which was very inappropriate, people were already next to each other skin to skin. As far as I understand, in a proper ceremony, you need to be 2 meters away from anybody. Coincidentally enough, that is about the distance the aura spans from the body, to prevent contamination once everybody's mind have been blown open. In that same ceremony I was invited as a by stander, and I saw one mental pathology bounce from mind to mind, the weakest link taking in all the grubby emotions from everybody else... poor guy. He ended up mumbling to himself in pain about a grandma that wasn't his and a loss he didn't live while the owner of the trauma suddenly felt great and was dancing.

I agree on the somewhat, the only place I know that is good to do ayahuasca is in the jungles of Perú with a tribe where the medicine is brewed properly and fresh by an elder that knows what he is doing. Just as the only hands that is proper to receive hikuri is from a marakame... The couple places I know that do such things also have someone not participating, and a doctor.
