If you do it, pay close attention to what's supposedly inside it. Both muscimol and ibotenic acid are supposed to be hallucinogenic, and both muscimol and ibotenic acid are in fly agric mushrooms. However, muscimol appears to be fairly non-toxic while ibotenic acid is neurotoxic and can cause scarring to the brain (sciencists apparently use it to cause brain lesions in rats for testing purposes). Despite this, from what I've seen it's hard to find edibles that don't have ibotenic acid.

Also, note that I said "supposedly" a lot. I tried a chocolate bar that supposedly had muscimol in it once. I felt a little odd the first time I tried it, but that was the full extent of my experience (I tried eating half the bar at one point to see if I just have a high natural tolerance, but that had even less of an effect). Additionally, I think I read a company recently got caught selling gummies that were just straight-up psilocybin.
