As seen on The Joe Rogan Experience!

WIth a new preface by Michael Pollan and an exclusive bonus chapter

A groundbreaking dive into the role psychedelics have played in the origins of Western civilization, and a real-life quest for the Holy Grail.

The most influential religious historian of the twentieth century, Huston Smith, once referred to it as the "best-kept secret" in history. Did the Ancient Greeks use drugs to find God? And did the earliest Christians inherit the same, secret tradition? A profound knowledge of visionary plants, herbs and fungi passed from one generation to the next, ever since the Stone Age?

There is zero archaeological evidence for the original Eucharist – the sacred wine said to guarantee life after death for those who drink the blood of Jesus. The Holy Grail and its miraculous contents have never been found. In the absence of any hard data, whatever happened at the Last Supper remains an article of faith for today’s 2.5 billion Christians. In an unprecedented search for real answers, The Immortality Key examines the archaic roots of the ritual that is performed every Sunday for nearly one third of the planet. Religion and science converge to paint a radical picture of Christianity’s founding event...and, after centuries of debate, to solve history’s greatest puzzle once and for all.

Before the birth of Jesus, the Ancient Greeks found salvation in their own sacraments. Sacred beverages were routinely consumed as part of the so-called Ancient Mysteries – elaborate rites that led initiates to the brink of death. The best and brightest from Athens and Rome flocked to the spiritual capital of Eleusis, where a holy beer unleashed heavenly visions for two thousand years. Others drank the holy wine of Dionysus to become one with the god. In the 1970s, renegade scholars claimed this beer and wine – the original sacraments of Western civilization – were spiked with mind-altering drugs. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The constantly advancing fields of archaeobotany and archaeochemistry have hinted at the enduring use of hallucinogenic drinks in antiquity. And with a single dose of psilocybin, the psychopharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers. But the smoking gun remains elusive.
