Overview: There is an Amazonian frog called Phyllomedusa Bicolor or the Sapo which I have been reading about for years. It is totally different from the psychedelic toads found in North America. The Sapo's venom produces an effect much closer to morphine than LSD, but really it's not like either of those things. It's a distinctly vomitous dissociative experience unlike anything else I've ever encountered.
