When psychedelics were made illegal, an underground emerged that included, academics, students, doctors, chemists and other enthusiasts. In 1961 Dr. Leo Zeff experimented with LSD and its role in the following decades is a crucial part of psychedelic history. As the Secret Chief, Leo’s pioneering influence as a guide cannot be ignored. Fifty years later at the MAPS 2010 conference in San Jose, James Fadiman acknowledged the underground guides expertise around psychedelics as the elephant in the room. His talk gave birth to the Guild of Guides. Six years later the Guild came to an end when it was outed in a RollingStone article. Permission has now been given to talk publicly about these gatherings. The GOG was rich in best practices and the tradition of modern peoples use of these medicines for the last 60 years.The hope is to be able to bring these experts in from cold.
