I suddenly became strangely inebriated. The external world
became changed as in a dream. Objects appeared to gain inrelief;
they assumed unusual dimensions; and colors became more glowing.
Even self-perception and the sense of time were changed. When the
eyes were closed, colored pictures flashed past in a quickly changing
kaleidoscope. After a few hours, the not unpleasant inebriation,
which had been experienced whilst I was fully conscious, disappeared.
what had caused this condition?

Experience of the world as matter, as object, to which man stands opposed, has produced modern natural science and technology — creations of the Western mind that have changed the world. With their help human beings have subdued the world. Its wealth has been exploited in a manner that may be characterized as plundering, and the sublime accomplishment of technological civilization, the comfort of Western industrial society, stands face-to-face with a catastrophic destruction of the environment. Even to the heart of matter, to the nucleus of the atom and its splitting, this objective intellect has progressed and has unleashed energies that threaten all life on our planet.

It's a forced disappearance...All those who have disappeared are related to the Causeway Bay bookshop and this bookshop was famous, not only for the sale, but also for the publication and circulation of a series of sensitive books.

I was seized by the dreadful fear of going insane. I was taken to another world, another place, another time. My body seemed to be without sensation, lifeless, strange. Was I dying? Was this the transition? At times I believed myself to be outside my body, and then perceived clearly, as an outside observer, the complete tragedy of my situation. I had not even taken leave of my family (my wife, with our three children had traveled that day to visit her parents, in Lucerne). Would they ever understand that I had not experimented thoughtlessly, irresponsibly, but rather with the utmost caution, and that such a result was in no way foreseeable? My fear and despair intensified, not only because a young family should lose its father, but also because I dreaded leaving my chemical research work, which meant so much to me, unfinished in the midst of fruitful, promising development. Another reflection took shape, an idea full of bitter irony: if I was now forced to leave this world prematurely, it was because of this lysergic acid diethylamide that I myself had brought forth into the world.

I believe that shortly after LSD was discovered, it was recognized as being of great value to psychoanalysis and psychiatry. It was not considered to be an escape. It was a very important discovery at that time, and for fifteen years it could be used legally in psychiatric treatment and for scientific study in humans. During this time, Delysid, the name I gave to LSD, was used safely, and was the subject of thousands of publications in the professional literature. Actually, just last week, I had visitors from the Albert Hofmann Foundation, to whom I gave all of the original documentation, which had been stored at the Sandoz Laboratories. This early work was very well documented, and shows how well research with LSD went until it became part of the drug scene in the 1960s. So, from originally being part of the therapeutic pharmacopeia, LSD became a drug of the street and inevitably it was made illegal. Because of this reputation, it became unavailable to the medical field, and so the research, which had been very open, was stopped. Now it appears that this research may start again. The importance of such investigations appears to be recognized by the health authorities, and so it is my hope that finally the prohibition is coming to an end, and the medical field can return to the explorations which were forced to stop thirty years ago.

It was obvious that a substance with such fantastic effects on mental perception and on the experience of the outer and inner world would also arouse interest outside medical science, but I had not expected that LSD, with its unfathomably uncanny, profound effects, so unlike the character of a recreational drug, would ever find worldwide use as an inebriant. I had expected curiosity and interest on the part of artists outside of medicine — performers, painters, and writers — but not among people in general. After the scientific publications around the turn of the century on mescaline — which, as already mentioned, evokes psychic effects quite like those of LSD — the use of this compound remained confined to medicine and to experiments within artistic and literary circles. I had expected the same fate for LSD. And indeed, the first non-medicinal self-experiments with LSD were carried out by writers, painters, musicians, and other intellectuals.

I know LSD; I don't need to take it anymore. Maybe when I die, like Aldous Huxley.

By observing natural scientific discoveries through a perception deepened by meditation, we can develop a new awareness of reality. This awareness could become the bedrock of a spirituality that is not based on the dogmas of a given religion, but on insights into a higher and deeper meaning. I am referring to the ability to recognize, to read, and to understand the firsthand revelations.

I was visited by Timothy Leary when he was living in Switzerland many years ago. He was a very intelligent man, and quite charming. I enjoyed our conversations very much. However, he also had a need for too much attention. He enjoyed being provocative, and that shifted the focus from what should have been the essential issue. It is unfortunate, but for many years these drugs became taboo. Hopefully, these same problems from the Sixties will not be repeated.

I think that in human evolution it has never been as necessary to have this substance LSD … It is just a tool to turn us into what we are supposed to be.

Muy sensible es la reacción de una comunidad de chimpancés en una jaula cuando un miembro de la familia toma LSD. Aunque en el propio animal no puedan comprobarse cambios, toda la jaula se alborota, porque el chimpancé con LSD aparentemente deja de cumplir con precisión las leyes del muy sutil orden jerárquico familiar.

This self-experiment showed that LSD-25 behaved as a psychoactive substance with extraordinary properties and potency. There was to my knowledge no other known substance that evoked such profound psychic effects in such extremely low doses, that caused such dramatic changes in human consciousness and our experience of the inner and outer world. What seemed even more significant was that I could remember the experience of LSD inebriation in every detail. This could only mean that the conscious recording function was not interrupted, even in the climax of the LSD experience, despite the profound breakdown of the normal world view. For the entire duration of the experiment, I had even been aware of participating in an experiment, but despite this recognition of my condition, I could not, with every exertion of my will, shake off the LSD world. Everything was experienced as completely real, as alarming reality; alarming, because the picture of the other, familiar everyday reality was still fully preserved in the memory for comparison. Another surprising aspect of LSD was its ability to produce such a far-reaching, powerful state of inebriation without leaving a hangover. Quite the contrary, on the day after the LSD experiment I felt myself to be, as already described, in excellent physical and mental condition. I was aware that LSD, a new active compound with such properties, would have to be of use in pharmacology, in neurology, and especially in psychiatry, and that it would attract the interest of concerned specialists. But at that time I had no inkling that the new substance would also come to be used beyond medical science, as an inebriant in the drug scene. Since my self-experiment had revealed LSD in its terrifying, demonic aspect, the last thing I could have expected was that this substance could ever find application as anything approaching a pleasure drug.

It gave me an inner joy, an open mindedness, a gratefulness, open eyes and an internal sensitivity for the miracles of creation... I think that in human evolution it has never been as necessary to have this substance LSD. It is just a tool to turn us into what we are supposed to be.

4/19/43 16:20: 0.5 cc of 1/2 promil aqueous solution of diethylamide tartrate orally = 0.25 mg tartrate. Taken diluted with about 10 cc water. Tasteless. 17:00: Beginning dizziness, feeling of anxiety, visual distortions, symptoms of paralysis, desire to laugh. Supplement of 4/21: Home by bicycle. From 18:00- ca.20:00 most severe crisis. (See special report.) Here the notes in my laboratory journal cease. I was able to write the last words only with great effort. By now it was already clear to me that LSD had been the cause of the remarkable experience of the previous Friday, for the altered perceptions were of the same type as before, only much more intense. I had to struggle to speak intelligibly. I asked my laboratory assistant, who was informed of the self-experiment, to escort me home. We went by bicycle, no automobile being available because of wartime restrictions on their use. On the way home, my condition began to assume threatening forms. Everything in my field of vision wavered and was distorted as if seen in a curved mirror. I also had the sensation of being unable to move from the spot. Nevertheless, my assistant later told me that we had traveled very rapidly. Finally, we arrived at home safe and sound, and I was just barely capable of asking my companion to summon our family doctor and request milk from the neighbors. In spite of my delirious, bewildered condition, I had brief periods of clear and effective thinking — and chose milk as a nonspecific antidote for poisoning.
