I’ve mentioned that psilocin, which is what psilocybin quickly becomes as it enters your metabolism, is 4 hydroxy dimethyltryptamine. It is the only 4-substituted indole in all of organic nature. Let this rattle around in your mind for a moment. It is the only 4-substituted indole known to exist on earth. It happens to be this psychedelic substance that occurs in about eighty species of fungi, most of which are native to the New World. Psilocybin has a unique chemical signature that says, “I am artificial; I come from outside.” I was suggesting that it was a gene – an artificial gene – carried perhaps by a spaceborne virus or something brought artificially to this planet, and that this gene has insinuated itself into the genome of these mushrooms.”
