Zach, a psychedelic researcher and advocate, offers a necessary overview of psychedelics today―particularly LSD, psilocybin, MDMA, and ayahuasca―including what they are, how to use them safely, and crucially, how to integrate mind- and spirit-altering experiences into the rest of our lives. Zach has a unique perspective on not only where psychedelics have been but also where they’re going. He offers context on both the cultural history and present interest, while acknowledging and honoring the Indigenous roots of many of these traditions.
