Delysid (LSD 25)

"As there are several detailed reports on the discovery of the psychotic and hallucinatory properties of Delysid (LSD 25), we shall confine ourselves to the salient features. During his investigations on the structure of the ergot alkaloids, Dr. A. Hofmann synthesized lysergic acid diethylamide. While working with the substance he experienced a strange, transient state of intoxication associated with changes in perception and personality. In order to ascertain the cause of this disorder he made a personal trial and ingested 250 millionths of a gram of Delysid. Even this small amount exerted dramatic effects: disturbances in the perception of space and time, depersonalisation and colored hallucinations. Subsequent systematic investigations showed that one-fifth of this amount i.e. 30 to 80 millionths of a gram, elicited mental changes reminiscent of symptoms of schizophrenia. An extraordinarily potent substance exerting specific effects on mental functions was thus discovered. It was destined to play a great role in experimental psychiatry.
Delysid has also enabled the doctor to gain an insight into the world of ideas of the mentally ill by experiencing schizophrenia-like symptoms himself. Such "model psychoses" can be studied in volunteers to evaluate therapeutic measures.
The release of inhibitions produced by Delysid has a therapeutic effect; it brings about the re-living of repressed emotional experiences and, by abreaction, facilitates psychotherapy.
The effect of Delysid on artistic production has also been studied under medical supervision. Delysid elicits a release of inhibitions and activates the subconscious without rendering the subject unconscious. Under the influence of Delysid a realistic mode of portrayal may undergo progressive distortion and result in a production reminiscent of abstract art.
It would be wrong to conclude from this that certain modern trends in art are manifestations of mental disorders. If they were, then so would be the artistic productions of primitive people and children. The important feature is the release of inhibitions consequent on the removal of control by reason which normally thrusts emotional experiences out of the consciousness into the subconscious, preventing them becoming active. Logical, rational thought is not alien to primitive peoples and to children even though these concentrate on intuition, pictorial thought and symbolism; their subconscious is not so repressed, can be more readily thrust into consciousness and can also be more easily traumatized, as is evidenced by running amok and falling into trances, reactions in which consciousness is temporarily absent and of which modern, rationally thinking man is not capable. This does not imply that Delysid can make an artist of each of us. The most that can be expected of the drug is activation of latent artistic tendencies. The creative faculties of the gifted artist are usually developed in a more natural way less frequently by the influence of alcohol (for instance E.T.A. Hoffman) or hashish ("paradis artificiel" of Baudelaire). "

LSD is synthetic, but it is derived from the natural substances known as ergot alkaloids, which are produced by ergot (Claviceps purpurea), a fungus that grows on rye, and also by certain members of the Convolvulaceae or morning -glory family, notably Rivea corymbosa, Ipomoea violacea or Ipomoea tricolor, Ipomoea carnea, Argyreia nervosa (Hawaiian baby woodrose) and Merremia tuberosa (Hawaiian woodrose)

  • Dose: LSD is one of the most powerful psychoactive drugs known. As little as 10 micrograms (ten millionths of a gram or .01 milligram) produces some mild euphoria, loosening of inhibitions, and empathetic feeling. The lowest psychedelic dose is 50 to 100 micrograms, and the intensity and profundity of the effects increase up to about 400- 500 micrograms, with individual variations; higher doses may prolong but do not further alter the experience. Only a tiny proporition of the drug actually reaches the brain. The lethal dose in man is unknown. One person is said to have taken 40 mg and survived; in the only reported case of death possibly caused by overdose, the quantity of LSD in the blood suggested that 320 mg had been injected intravenously. Tolerance (resistance to the drug effect) develops quickly- within two or three days - and disappears just as fast.
  • Physiological effects: These are extremely variable and more or less independent of dose. The most common effect are especially conspiciuous in the first hour, before the psychological effects become obvious; dilation of the pupils (the most nearly universal symptom); increase in deep tendom reflexes; increased hear rate, blood pressure and body temperature; mild dizziness or nausea, chills, tingling, trembling; slow deep breathing; loss of appetite and insomnia. Most of the symptoms of sympathomimetic; they indicate activation of the sympathetic nervous system, which prepares the body physically for emergencies. But none of these symptoms is always present; there opposite might appear instead. LSD probably produces a broader spectrum of physical symptoms than any other drug, almost all of them secondary effects of the complex psychological changes. Most physiological measurements- liver function, serum cholesterol, urine, and so on- are unaffected. LSD is almost completely metabolized in the body; very little is excreted unchanged in the urine.

In April 1943 a research chemist at the Swiss Headquarters of the Sandoz drug company had made an extraordinary discovery. Dr. Albert Hoffman was attempting to synthesize a drug from ergot, a fungus which attacks cereals. He began to feel dizzy, tipsy and restless. Hoffman lay down in the hope that the effects would soon pass off. But they did not. As a succession of colours and patterns drifted across his consciousness, he took the first LSD 'trip'.
Hoffman's discovery of LSD soon began to interest psychiatrists who wondered whether a drug which appeared to open the doors of perception might be valuable in treating mental illness. The results of their experiments were soon known to the chemical warfare scientists in all three members of the Tripartite Agreement, who began to evaluate the drug as a potential weapon.
The early results seemed encouraging.
"The British had found that LSD had great value in dealing with psychopaths. The Canadian Psychiatric Association Journal reported good results with LSD in reversing frigidity and sexual aberrations. American mental hospitals reported that treatment of schizophrenic children which LSD met with some success when all other known methods had failed," reported an American assessment.
