The Wikipedia page ( https://en.wikipedia.org/wiki/Hallucinogenic_bolete_mushroom ) talks about effects lasting for days, even in animal studies. Some of the historical records claimed effects lasting even longer, from months to years, though this sounds like triggered psychosis.
So perhaps not very recreational as might be assumed given the topic.
Sorry to use a reddit-ism, but "this should be at the top" - for safety.
"Days"?!? Hard pass. My experiments with shrooms in college was fun, but I couldn't deal with the 8-12 hours of hallucinating.
I wonder if Hamilton Morris has tried it yet. Hamilton, if you're reading let us know when you're going to let us hear about it :)
For anyone vaguely interested in psychoactive/psychedelic drugs, his books and videos are amazing:
