But you know what? Those are the exceptions. I've taken ayahuasca dozens of times, and am booked for another trip to Peru next month. I've been fortunate only to work with reputable people, and have consistently only met others in my travels that have also worked with reputable people.
Please don't judge a tradition that's thousands of years old, and actually remarkably safe — with a few caveats, that the reputable folks will screen for — on the basis of a couple of cretins who look at the plants and the gringo tourists and just see dollar signs.
I've never done it, but I have a strong sense that pharmahuasca would be cold, sterile, and missing some of the je ne sais quoi that the "shaman piss" [1] experience offers. I'm sure it would still be a valuable experience, and one I'd be open to exploring, but drinking trees works well enough for me, thanks.
I mean, sure you can puke (I often do, sometimes several times in the course of a night), and it tastes horrible, and your sweat smells like tree bark at the end of the night — let alone the end of the week. That's just the process, though, and "optimizing" it out would probably also remove many of the things that are actually among the most valuable (for me, and everyone else who does this more than once with whom I've spoken) aspects.
EDIT: footnote added.
[1] Interestingly, in one of the earliest-documented shamanic traditions, tribes on the Siberian steppe would use amanita muscaria mushrooms, which are visionary, but also mildly toxic. The shaman would take a shaman-sized dose, and journey, then collect his urine (which still contains threshold doses of psychoactive metabolites), and serve that to his "patients".
I agree about set and setting. The "clinics" I picture are probably not what that word normally conjures up.
I'd be fascinated to know then if certain underlying themes and insights would remain similar or not. So far the western experience with psychedelics does show some commonality with that of indigenous peoples-- it's common for people to report a kind of cosmic oneness experience, insights about their character, etc. But there are also unique cultural twists. Ours have a flavor reminiscent of Greek and Roman Dionysian and Bacchanalian ceremonies, and then there is stuff like:

Somewhat off topic question but I'd like to ask anyway - How exactly do you know its thousands of years old ?
I'm not saying it isn't, but how do you know for sure ?
The MAOI has a prolonging and intensifying effect, and has psychedelic effects of it's own. Smoking DMT isn't the same as eating pharmahuasca, which isn't the same as drinking ayahuaska.
That said, it is very, very rare for anyone to have a reaction. The quality tours have trained medics in the village, and the villages are jammed deep in the forest like some of the hippy tours.
Smoking DMT is a very clean experience. It is intensely visual in nature and completely cerebral.
Pharma/Ayahuaska is a heavy body load as you drift in and out of the altered state often called "hyperspace".
I don't really recommend the MAOIs because of the complications they can cause, and you can have just as spiritual of an experience without drinking their "jungle juice". haha ;)
Somehow I don't derive much reassurance from that. :\ I guess some people are just more comfortable rolling the dice with their brains than I am...
I feel the same way with people who take pharmaceutical anti-depressants.
If you live in a major urban area, and hang around in the right circles, it's very likely you can find a local party with which to partake, and thus get to take advantage of top-notch medical care in case of emergency (if that's your worry).
I strongly suspect that with psychedelics, the context in which they are taken is far more influential on the kind of experience you have than the actual neurochemical effects. A sugar pill given to you by a man in a white coat and a soothing bedside manner is going to have a bigger effect than the same pill given to you by your next-door neighbor the handyman.
The service these fake shamans are providing can be of value even though the shamans are fake.
With proper research and preparation, the 'jungle juice' is remarkably safe to consume.
Why appeal to the age of an authority? If there's anything measurably beneficial about Ayahuasca I'm certain it can be extracted into a precisely dosed pharmaceutical.
The danger of your opinion is that it precludes research into things like drumming and chanting. Humans have been using rhythm to build a sense of community for thousands of years. Could there be something here for science? Could we learn how to help therapists and patients bond much faster?
I don't know these answers. Do you?
The shaman by him/herself won't do anything. Neither would the Ayahuasca on it's own. It's having the right combination of both (setting), and your intention (set) that leads to an amazing experience.
The funny thing is, the experience itself is not the most important thing.. it's what you do after the ceremony with your life, and how you change your lifestyle to make you happy.
Obviously, if the shaman isn't giving you the real tea, mixes stuff in, doesn't take care of you, and such, I'd call it a straight up scam.
If you like, you can think of it as a kind of placebo effect. Which, you may be able to imagine, can get really strong under the influence of psychedelics.
Disclaimer: I've never used Ayahuasca, but I did organise a few shroom trips, where I paid a lot of attention to the "set & setting". Compared to other times, it makes a lot of difference.

The first article is not about ayahuasca, but provides some excellent advice for spiritual seekers. The second is the best article. The third is CNN, but it is likely the incident the OP is talking about.
Ayahuasca and salvia both completely scare me. They are not meant to be administered recreationally, and they can both bring about some states that can lead to dangerous behaviours or permanent mental illness. However, if administered correctly by a well trained shaman, each have therapeutic qualities.
The problem is too many people with western dollars read Carlos Castaneda and embark in search of a shaman. And, there are many unscrupulous people who will say anything to make a buck.
