>>610879It's been mentioned several times but I feel I should clarify.
LSD was isolated and synthesized from a type of fungus. LSA is also similar and can be found in morning glory seeds. It comes from nature, it's just very concentrated when it's synthesized in drug form. Also, most street LSD these days is not actual LSD and/or is not pure LSD. Most often they are NBOMe's like 2C-E or 2C-I that are marketed as LSD. Fungi are a complex group of organisms but the most common used to "trip" from are psilocybin mushrooms which can be found on cow patties after a good rain.
That said, nature is my favorite place to trip, there's lots of relatively harmless stimuli to enjoy and if you're not around bad people it's harder to have a bad trip out there, in my opinion. But I'm a biologist and experienced tripper. If you generally hate nature it might not be good for you. Set and setting are everything.
