Getting high as shit has had an important cultural role in most of the world at one point in time or another. Westerners got away from it post-Christendom but even then it’s been a thing basically everywhere at one point or another, unless nothing psychedelic grows there, and even then there are ways to achieve ecstatic states to roughly similar effect through extreme asceticism - if there’s not something to eat or smoke to get there then your shaman might have to starve and dehydrate himself then be suspended in the air through rods run through his chest, but you can get there either way.
