Why Would Anyone Need Sapo/Kambo Training?

Someone on a social media platform asked me what I thought of people being trained in kambo --frog sweat -- medicine by an organization called IAKP which has been training people in the medicine use for several years now. They suggested that indigenous kids just get the medicine a couple of times and are good to use it on themselves and others. This was my response:

I do not have any direct experience with IAKP, but have met some of their practitioners and they appear well trained. I know that when I occasionally train people -- and I don't know where I get the right to do that other than wanting people to use the medicine in a careful and positive fashion -- it is not at all similar to someone being brought up in an indigenous culture that depends on the medicine for hunting, for eliminating the grippe, and so forth. Those kids are around the medicine from birth, just like they are around the jungle from birth and so are at home with it without any need for formal training. But then you take a kid from Whitestone, Queens, New York, like me and put me in the jungle and I need lots of training to be able to survive well out there. I think the same applies to sapo/kambo training. 
Yes, a person can just use it once or twice and then give it to other people, but what happens when something goes wrong? What happens when you allow a guest to walk, unattended, to a bathroom and they black out and hit their head on a counter top? Or wind up with their head in a bad position and start to vomit and then choke and panic? What do you do when someone absolutely freaks out on taking the medicine? There are so many things to learn to use the medicine in our cultures that it is impossible to compare the learning to indigenous culture learning. I have guests who need two or three hours to come together again after a session, and other guests who are good to go 20 minutes after initial application. How do you judge when to give them back their car keys and let them drive off? 
I am not a believer in shrouding the medicine in a whole lot of mysticism and pomp theatrics, but I do sing people into the first four or five minutes of the experience to help them go into it gently -- as you all know it's darned abrupt!!! So while I do not know the IAKP directly, I think that training people to the things to be aware of prior to serving others, is probably a good thing. And I do not know what they charge, but if they are giving you 10 days or two weeks' attention, well, someone has to get paid to do that. That is a lot of work.
