History of LSD
PREFACE
There are experiences that most people hesitate to talk about, because they do not fit into everyday consensus reality and defy rational explanation. We are not speaking of external occurrences, but of internal subjective transformations, which are frequently dismissed as mere illusions and banished from memory. The familiar image of the surrounding world undergoes a sudden, strange alteration—joyous or terrifying—appearing in an entirely new light and taking on profound significance. Such an experience may touch us fleetingly like a gentle breeze, or burn itself permanently into our consciousness.
From my own childhood, I retain a particularly vivid recollection of such an enchantment. It was a radiant morning in May. I no longer recall the exact year, but I can still point out the precise spot on the forest footpath of Martinsberg, north of Baden, Switzerland. As I strolled through the fresh green woods, the morning sun filtered down through the canopy of the trees. The forest was filled with birdsong. Suddenly, everything stood revealed in an unusually brilliant, lucid light. Had I never truly looked before, and was I now perceiving the spring forest as it actually existed? The landscape shone with an eloquence that touched my soul in an indescribable way, as if inviting me into its radiant being. An overwhelming feeling of joy, belonging, and boundless peace washed over me.
I do not know how long this enchanted state persisted, but I clearly remember the thoughts that occupied my mind as the transfiguration slowly faded and I resumed walking. Why could this blissful revelation not endure, when it felt like a deeper, authentic reality revealed through immediate, profound experience? My overflowing joy urged me to share this discovery with someone, but I immediately sensed that no words could articulate what I had perceived. It seemed strange to me that a child had witnessed something so wondrous that adults evidently did not perceive, for I had never heard anyone speak of it.
In subsequent years of my youth, I experienced several more of these spontaneous visionary episodes during walks through meadows and forests. They fundamentally shaped my worldview, providing me with the unshakeable certainty that a deeper, living, fathomless reality lies hidden behind everyday perception. At that time, I often wondered whether, upon reaching adulthood, I would ever be able to convey these experiences to others, perhaps communicating them through poetry or painting. But I felt no artistic gift for poetry or the visual arts, and so it seemed I would keep these transformative encounters locked within myself.
From Chemistry to Hallucinogens
In an unexpected, yet surely meaningful way, it was not until the midpoint of my life that a connection emerged between my professional work and the visionary epiphanies of my childhood. Seeking to understand the fundamental architecture and essence of matter, I studied chemistry. Having felt an intimate kinship with the plant kingdom since boyhood, I chose as my research field the chemical investigation of active substances in medicinal plants. There I encountered psychoactive, vision-inducing compounds that, under specific conditions, provoke altered states of consciousness closely mirroring the spontaneous experiences of my early years. The most famous of these compounds became known throughout the world as LSD. Certain hallucinogens entered biological and psychiatric research as valuable scientific tools, while achieving widespread, controversial dissemination across youth culture, especially LSD. Studying the literature surrounding these substances, I recognized the profound cultural importance of visionary contemplation throughout history. It occupies a central role not only in comparative religion and mysticism, but in the creative processes of literature, visual art, and science. Modern investigations have revealed that many individuals experience spontaneous visionary moments in daily life, though they rarely recognize their value or significance. Mystical experiences like those of my childhood are far from rare anomalies.
A deeper and more comprehensive understanding of reality than that afforded by ordinary rational consciousness is sought today along many avenues, not only by followers of Eastern spiritual traditions, but also by mainstream psychiatrists who incorporate holistic visionary states as foundational therapeutic catalysts. I share the conviction of many contemporaries that the spiritual crisis pervading the Western industrialized world can only be resolved if we replace the materialist paradigm—which alienates human beings from their living environment—with an expanded awareness of reality that integrates the perceiving self, recognizing that humankind, living nature, and the cosmos constitute an inseparable whole.
Consequently, all instruments and pathways capable of fostering such a fundamental renewal of our experience of reality deserve serious investigation. Foremost among these are diverse contemplative and meditative disciplines, both sacred and secular, aimed at inducing mystical experiences of wholeness and cultivating deeper awareness. Another vital, albeit contentious, avenue is the thoughtful application of consciousness-altering hallucinogens. LSD, for example, can serve as a potent psychoanalytic and psychotherapeutic tool, enabling patients to perceive their psychological conflicts in their authentic context.
My Problem Child
Unlike spontaneous visionary experiences, deliberately inducing unitive mystical states—particularly through LSD and related chemical substances—entails profound hazards that must never be underestimated, given their power to reach into the deepest foundations of the human psyche. The history of LSD demonstrates all too clearly the catastrophic consequences that arise when its profound potency is treated casually, confusing a transformative sacrament with a recreational stimulant. Careful preparation, both internal (set) and external (setting), is indispensable if an encounter with LSD is to prove fruitful and safe. Widespread careless use and social misunderstanding turned LSD into my problem child.
In this book, I aim to provide a comprehensive account of LSD, its origins, pharmacology, and therapeutic applications, while warning candidly against the dangers of applications that ignore its singular properties. I believe that if medicine and contemplative practice can properly harness LSD’s capacity to induce visionary states under guided, responsible conditions, my problem child may yet mature into a child of wonder.
