With pharmahuasca or ayahuasca analogues maybe. With a normal/traditional brew it's essentially impossible to overdose (think like 3-4 liters of the stuff). Analogues like syrian rue are a lot easier to overdose though, it's a pretty small amount of material needed.

Also the vast majority of people are done purging within a few hours...not "days"

(Source: work at retreat center and have drank hundreds of times)

You seem to know, what you are doing. Is the retreat center where you work located in europe?

>>lukan+Eq
No (and sorry I don't know enough european centers to suggest any. My perspective is that the substance you drink is only one part of it, the curandero and their experience is the other, and I can't imagine there would be a lot of traditional experience over there)

"and I can't imagine there would be a lot of traditional experience over there"

No, not much. But plenty of new age shamans, who are spiritual, because they flew into the Amazonas once.

"My perspective is that the substance you drink is only one part of it"

Definitely. When I did it with brasilian Santo Deime folks, I was part of the whole ceremony, including cooking it traditionally for a long, long time and preparing mentally for it. Something like this I would like to do again at some point.
