Bringing the subject back to Mr. Iye, I recently had the pleasure of seeing him speak, and I walked away with very mixed feelings about his practice. Obviously if it works for him, then that's great and he should keep on trucking, but I'm not sure how comfortable I am with the way he broadcasts it.
While is was very witty, and is obviously sharp as a tack, he said some things that made me raise an eyebrow a few times (there was a long section about super soldiers, the Cold War, and communist Berlin, littered with references to Marvel comics). The whole thing felt very...tangential? Unfocused? Snozz and Joedirt were also there, so they might have other opinions.
While he might be able to handle it, I think there is a very real chance that someone else could get inspired by him, and end up going completely off the deep end, especially if they already were a little unstable to begin with.
It's certainly not the kind of thing I would try without *years* of tripping experience under my belt, and honestly, I don't think even then. At a certain point, I find you just can't take stuff back with you.
