Quotes from the Interview
“If I told you there was a plant that you could take that gave you a slight lightness of being, a slight kind of skip in your step, a sense of well-being that eliminated all these sort of existential little neuroses that we all suffer as conscious beings, and it allowed you to focus at task whatever that creative task was, whether it was a spinning of wool or the writing of digital code, and you could sit at task all day long concentrating on task with immense focus, with no sense of being under the influence of any plant, nothing as harsh as a second cup of coffee, and you found yourself at the end of the day ready to go home, have dinner, and do it all over again the next day, the truth is that coca has this capacity to improve our lives.”
— Wade Davis
“[Coca is] as important to that population as peppermint and chamomile are in European medicine. It’s their major medicinal plant.”
— Andrew Weil
“Coca has been used in South America by virtually every culture of the Andean and Northwest Amazon for 8,000 years. And during that time, there’s been no evidence whatsoever of any toxicity, let alone addiction.”
— Wade Davis
“In coca, there are 14 alkaloids. Cocaine is one of them. They all have similar chemical structures and none of them have ever been studied. Once we isolated cocaine from the leaf, everybody lost interest in everything else.”
— Andrew Weil
“Coca is to cocaine what potatoes are to vodka.”
— Wade Davis
“As the anthropologist Catherine Allen said, to deny people coca in the Andes is not like denying the Germans beer or the British tea or the French coffee. It’s actually an act of cultural genocide because you cannot be runakuna, you cannot be of the Andes, of Pachamama, if you do not use the leaves.”
— Wade Davis
“I think that coca is the most perfect example of how we’ve gone wrong in our relations with the natural world, really failing to see that plant for what it is, confusing it with this one component of it, and then getting ourselves in enormous amounts of trouble.”
— Andrew Weil
“I feel that liberating coca is the final act of my professional life. I feel that very sincerely.”
— Wade Davis

Listen to this one with ethnobotanist Dr. Mark Plotkin, in which we learned about the 8,000-year history of the coca leaf, the varieties of coca and their uses, coca-leaf bonding among the Kogis of Northern Colombia, surviving altitude sickness in the Andes, the adventures of Richard Evans Schultes, ayahuasca and shamanic knowledge, the biocultural conservation of the rainforest, and much more.
