How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence
Michael Pollan (2018); Penguin Press
When Michael Pollan set out to research how LSD and psilocybin (the active ingredient in magic mushrooms) are being used to provide relief to people suffering from difficult-to-treat conditions such as depression, addiction and anxiety, he did not intend to write what is undoubtedly his most personal book. But upon discovering how these remarkable substances are improving the lives not only of the mentally ill but also of healthy people coming to grips with the challenges of everyday life, he decided to explore the landscape of the mind in the first person as well as the third. Thus began a singular adventure into various altered states of consciousness, along with a dive deep into both the latest brain science and the thriving underground community of psychedelic therapists. Pollan sifts the historical record to separate the truth about these mysterious drugs from the myths that have surrounded them since the 1960s, when a handful of psychedelic evangelists inadvertently catalyzed a powerful backlash against what was then a promising field of research.

LSD: My Problem Child
Albert Hofmann (1979); McGraw-Hill
This is the story of LSD told by a concerned yet hopeful father, organic chemist Albert Hofmann. He traces LSD's path from a promising psychiatric research medicine to a recreational drug sparking hysteria and prohibition. In LSD: My Problem Child, we follow Dr. Hofmann's trek across Mexico to discover sacred plants related to LSD, and listen in as he corresponds with other notable figures about his remarkable discovery. Underlying it all is Dr. Hofmann's powerful conclusion that mystical experiences may be our planet's best hope for survival. Whether induced by LSD, meditation, or arising spontaneously, such experiences help us to comprehend "the wonder, the mystery of the divine in the microcosm of the atom, in the macrocosm of the spiral nebula, in the seeds of plants, in the body and soul of people." More than sixty years after the birth of Albert Hofmann's problem child, his vision of its true potential is more relevant, and more needed, than ever.

The Psychedelic Explorer's Guide: Safe, Therapeutic, and Sacred Journeys
James Fadiman (2011); Park Street Press
Called "America's wisest and most respected authority on psychedelics and their use," James Fadiman has been involved with psychedelic research since the 1960s. In this guide to the immediate and long-term effects of psychedelic use for spiritual (high dose), therapeutic (moderate dose), and problem-solving (low dose and microdose) purposes, Fadiman outlines best practices for safe, sacred entheogenic voyages learned through his more than 40 years of experience--from the benefits of having a sensitive guide during a session (and how to be one) to the importance of the setting and pre-session intention. Fadiman reviews the newest as well as the neglected research into the psychotherapeutic value of visionary drug use for increased personal awareness and a host of serious medical conditions, including his recent study of the reasons for and results of psychedelic use among hundreds of students and professionals. He reveals new uses for LSD and other psychedelics, including microdosing, extremely low doses for improved cognitive functioning and emotional balance.

Richard Louis Miller (2017); Park Street Press
Embracing the revival of psychedelic research and the discovery of new therapeutic uses, clinical psychologist Dr. Richard Louis Miller discusses what is happening today in psychedelic medicine--and what will happen in the future--with top researchers and thinkers in this field, including Rick Doblin, Stanislav Grof, James Fadiman, Julie Holland, and Dennis McKenna. Dr. Miller and his contributors cover the tumultuous history of early psychedelic research brought to a halt 50 years ago by the U.S. government as well as offering non-technical summaries of the most recent studies with MDMA, psilocybin, LSD, and ayahuasca. They explore the biochemistry of consciousness and the use of psychedelics for self-discovery and healing. They discuss the use of psilocybin for releasing fear in the terminally ill and the potential for MDMA-assisted psychotherapy in the treatment of PTSD. They examine Dr. Charles Grob's research on the indigenous use and therapeutic properties of ayahuasca and Dr. Gabor Mate's attempt to transport this plant medicine to a clinical setting with the help of Canada's Department of National Health.

The Doors of Perception and Heaven and Hell
Aldous Huxley (1956); Harper Perennial
In 1952, Aldous Huxley became involved in the early psychedelic movement with an experiment that involved 400 mg of mescaline. The psychedelic drug produced a visionary experience that he compared to the mystical experiences of mystics and saints. The experience led him to write "The Doors of Perception," a philosophical essay detailing his experience. The book takes its title from a phrase in William Blake's poem "The Marriage of Heaven and Hell." Huxley recalls the insights he experienced, ranging from the "purely aesthetic" to "sacramental vision," and reflects on their philosophical and psychological implications. "Heaven and Hell" is an essay by Aldous Huxley published in 1956, which discusses the nature of mystical experience and its relationship to art and symbolism. It was published as a companion piece to "The Doors of Perception." Together, these essays explore the relationship between psychedelic experiences, art, spirituality, and the nature of reality, offering profound insights into altered states of consciousness and their significance for human understanding.
