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.
LSD had the same duration with me, but more psychological & emotional impact. So I avoided it for two reasons. Weirdly, all my divorced 50+ year-old male peers are now into K and DMT. They are raving about DMT, but I feel like my brain is too frail-as-is.
Nah. Everything I've read about hallucinogens says dose doesn't change effect duration, only intensity. Drugs do affect people differently, so I wouldn't jump straight to saying they're exaggerating.
Also, 12 hours is definitely not short of LSD. I'd say it's the standard duration, with the peak lasting 7 hours. Longer trips can happen, at least to some people, but the default assumption should be about half a day.
definitely not hyperbole. last time i took LSD i dropped at 5pm before going to dinner and ended up at a bread factory 15 miles away at 5am watching them run the big mixers. no idea how i got there just remember walking all night.
