The main focus on naturally occurring psychedelics has been on a few dozen species identified in North and South America. For example, the Western world knows of roughly 100 species of psychedelic mushrooms. Is this a bias from our bioprospecting or a true distribution of psychedelic plants and animals?
I hesitate to mention the vast collection of psychedelic flora and fauna that grow and live around us, which could encourage their overuse by humans. Any advancement or discovery in this realm should be done responsibly to mitigate the risks to these species. Modern history has focused on a small population of natural producers of psychedelics when in reality this is a vast area with opportunities.
