What you’re referencing are Aminita Muscaria mushrooms. The active hallucinagenic compound is not psilocybin but rather muscimol. Psilocybin is a classic psychedelic, while muscimol is a depressant with sedative and dissociative properties.
It is true that muscimol doesn’t break down completely after ingestion, and shamans have used reindeer urine to consume what was left over.
I’m not sure how much psilocin (a metabolate of psilocybin) remains in urine, but it stands that the two compounds are very different, and interact with the human nervous system differently, even though the perceived effects are similar.












This is untrue. In many cooking styles using animal based stock as the entire foundation of the dish is completely normal. Subbing veggie stock isn’t always possible given the chef is going for a certain flavor profile. Veggie fond is not the same as animal fond, which also changes the flavor. Animal proteins denature differently, and some proteins are specifically used for their chemical and physical properties (think cream for a sauce, or eggs for a souffle).
While it is usually possible to sub vegan ingredients to approximate most of the effects of non-vegan ingredients, doing so entirely changes the flavor profile, presentation, and shopping list.
Can it be done? Absolutely. Is it as trivial as you make it out to be? Not even close.
I say this as a seasoned chef who has worked in commercial kitchens and cooks 3 meals a day at home from scratch. When I know I have guests coming over for a meal I attempt to accommodate for their dietary requirements (this doesn’t just apply to vegans), but it is rarely as easy as leaving one thing out. It usually means making two (or more) sets of completely separate mains and sides, which doubles the work and significantly increases the time spent.
