How Much Does Culture Influence the Psychodelic Experience?

There's a lot of good reasons to focus on iwaska use in south american countries. Different groups living relatively close to one another can have very different traditions around the use of iawaska. The question at stake is how much does culture impact the psychodelic experience, versus how much is inherent to the way tat these particular substances interact with our perceptual and cognitive systems? I find that a fascinating question, and it's one for scholars and scientists to understand.
