The Ayahuasca Test Pilots Handbook provides a practical guide to ayahuasca use, aiding seekers in making right—and safe—decisions about where to go, who to drink with, and what to expect. Ayahuasca, the Amazonian psychoactive plant brew, has become vastly popular. Once the sole purview of shamans and indigenous native people in the great Amazon rainforest, ayahuasca is now becoming well known—and widely used—around the globe. Today, foreigners from all over the world flock in ever-burgeoning numbers to the steamy Amazon, drinking bitter ayahuasca with shamans and curanderos in order to access its potent healing and spirit-enlivening effects. What began as a mere trickle of visitors in the 1980s has become a surging riptide of seekers. Chris Kilham has worked closely with South American shamans for two decades and has sat in ayahuasca ceremonies with at least 20 different shamans. Through his "Ayahuasca Test Pilots" program, Kilham has brought numerous people to the Amazon to engage in ceremonies with maestro ayahuasceros.
