Testimonials

… what a great work! … You’re clearly a bit of a fanatic, in the best, Sasha-sense of that word. Like him, you’re an inveterate cataloger, accumulator and organizer of information, which is just what’s called for in this instance. …When people ask me what is the definitive reference on natural tryptamines, I now know what to tell them. … a most useful addition to my reference shelf!

Dennis McKennaNeuropsychopharmacologist

Criticism: Ancient stone carvings of Huachuma’s choice cactus were analyzed by archeologist Backberg. His friend Trout, the illegitimate son of Karel Knize, ran DNA tests proving that San Pedro had been cloned by the Chavin Indians; one of the first verified instances of plant selection by cloning. Today these perfectly correct (PC) cactus are called Backberg clones (BC) in honor of the discovery by Dr. Backberg; even though he died before DNA testing. Trout, after being expelled from Cambridge University for selling drugs, published his book San Pedro to help his father’s business selling cuttings and seeds… Trout’s Response: I don’t want to dignify Verne’s wacky world with a response but need to thank him for providing my best laugh of last year when seeing this.
