Psilocybin Mushrooms
Timeline
| 1000 - 500 BCE | Central American cultures build temples to mushroom gods and carve "mushroom stones" found in Mexico & Guatamala. 1 | |
| c. 290 CE | Chang Hua's "Record of the Investigation of Things" (Po-wu chih) describes what may be hallucinogenic mushrooms in Chin Dynasty China. | |
| 13th Century | In his treatise "De Vegetabilibus", Albertus Magnus cautions against eating mushrooms that "stop up in the head the mental passages of the creatures [that eat them] and bring on insanity". 2 | |
| 13th - 15th Century | Vienna Codex depicts the ritual use of mushrooms by the Mixtec gods, showing Piltzintecuhtli and 7 other gods holding mushrooms in their hands. These were most likely psilocybin-containing mushrooms. (The Wondrous Mushroom) | |
| 16th Century | Xochipilli statue carved. Aztec statue depicts the Prince of Flowers decorated with 6 psychoactive plants: mushrooms, tobacco, morning glory, sinicuichi, cacahuaxochitl, and one unidentified. | |
| Jun 15, 1521 | The use of hallucinogenic mushrooms and peyote are driven underground as use of "non-alcohol" intoxicants is forbidden by Europeans in Mexico. Catholic priests punish the use of entheogens by native people. | |
| 16th Century | Dutch physician Pieter van Foreest describes a case of a woman who was "flung into violent convulsions and the Riscus sardonicus [fixed grin, or uncontrollable laughter] by eating mushrooms". 2 | |
| 16th Century | Codex Magliabecchiano written and illustrated, with at least one depiction of teonanácatl. 3 | |
| 1560 | Spanish priest Bernardino de Sahagún writes in his Florentine Codex about the use of peyote and hallucinogenic teonanacatl mushrooms by the Aztecs. He estimates peyote has been in use since at least 300 B.C. 4 | |
| 1772 | Physician W. Heberden writes to the Gentlemen's Magazine of a family eating mushrooms, which rendered them "all much disordered". The man "was unable to shut his eyes and was so giddy he could hardly stand; the woman felt the same symptoms in a more violent degree; and the child, who had but just tasted them, had convulsive agitations in its arms." 2 | |
| Oct 3, 1799 | First psychedelic mushroom experience/ingestion documented in a scholarly journal takes place in London. Dr. Everard Brande attends a family whose members, upon eating wild mushrooms, were seized with visions and laughter. The mushrooms were examined and determined to be Agaricus glutinosus, later reclassified as Psilocybe semilanceata (Liberty Caps). 5 | |
| Mid 1800s | Xochipilli statue discovered by Europeans in central Mexico. | |
| Aug 1904 | American mycologist Franklin Sumner Earle (1856-1929) is the first to collect identified Psilocybe cubensis (originally designated Stropharia cubensis) in Cuba. | |
| 1936 | Blas Pablo Reko confirms the existence of teonanacatl as the psilocybin mushroom, refuting the scholarly misunderstanding of that time that teonanacatl was peyote. | |
| 1938 | Schultes and Reko travel to Mexico and collect specimens of several psychoactive mushroom species which are deposited in the Harvard herbarium. | |
| 1938 | American anthropologist Jean Basset Johnson and his wife Irmgard Weitlaner become the first "modern" white people to witness a mushroom velada (healing ceremony) in Huautla, Mexico. 6 | |
| 1939 | Richard Evans Schultes publishes a paper describing teonanacatl as a specific psilocybin-containing mushroom. (Probably the first academic release of this fact.) | |
| 1953 | Amateur mycologist R. Gordon Wasson visits Oaxaca Mexico and sits in on a mushroom velada. In 1954 returns to Huatla with Alan Richardson a photographer, to 'complete' his research of mind altering mushrooms. He returns again in 1955 with Richardson for the fateful velada with Maria Sabina. | |
| Jun 29, 1955 | R. Gordon Wasson and photographer Allan Richardson participate in a mushroom velada led by Maria Sabina. | |
| May 13, 1957 | Wasson publishes an article about psychoactive mushrooms in Life Magazine, the first popular media coverage of their existence. | |
| 1958 | Psilocybin is first isolated from psychoactive mushrooms by Albert Hofmann working at Sandoz Pharmaceutical in Switzerland. 7 | |
| 1959 | Albert Hofmann first publishes the synthesis of psilocybin. 8 | |
| 1960 | Sandoz Pharmaceutical begins producing psilocybin pills. They contain 2 mg of psilocybin per small pink pill. | |
| Aug 1960 | Timothy Leary first ingests psilocybin-containing mushrooms in Cuernavaca, Mexico. 9 [Details] | |
| Oct 1960 | Timothy Leary first tries pure psilocybin. 9 [Details] | |
| 1960-1961 | Timory Leary and Richard Alpert begin a series of experiments with Harvard graduate students, using pure psilocybin. 7 | |
| 1960s | Hofmann gives synthetic psilocybin to Maria Sabina. | |
| Apr 1962 | Good Friday Experiment - 20 students at Boston University participate in a psilocybin ritual/experiment. 10 [Details] | |
| 1963 | Leary and Alpert were dismissed from their academic positions at Harvard due, at least in part, to their continued experiments with students and psychedelics. 7 | |
| Oct 24, 1968 | Possession of Psilocybin & Psilocin are banned federally in the U.S. after the passage of the Staggers-Dodd Bill (Public Law 90-639) which amended the Food, Drug, and Cosmetic Act. | |
| Oct 27, 1970 | The Comprehensive Drug Abuse Prevention and Control Act is passed. Part II of this is the Controlled Substance Act (CSA) which defines a scheduling system for drugs. It places most of the known hallucinogens (LSD, psilocybin, psilocin, mescaline, peyote, cannabis, & MDA) in Schedule I. It places coca, cocaine and injectable methamphetamine in Schedule II. Other amphetamines and stimulants, including non-injectable methamphetamine are placed in Schedule III. | |
| 1960-1977 | Psilocybin is studied as a psychotherapeutic medicine through the 1960s and 1970s. FDA approved research with humans ends in 1977, not to be continued until the late 1990s. | |
| Late 1990's | Research with psilocybin begins to see a small resurgence. | |
| Jun 1999 | An improved synthesis method for psilocybin is published. 11 [More Info] | |
| 2002 | Possession and sale of psilocybin containing mushrooms becomes legal in the U.K. due to a statement from the Home Office that they are not illegal as long as they have not been prepared in any way. | |
| Jun 5, 2002 | Japan. Psilocybin mushrooms become illegal to sell in Japan. Although already illegal to eat, Japanese head shops had previously been allowed to sell mushrooms. | |
| 2003 | Mushroom selling stalls and storefronts pop up around England, especially in London. | |
| Jul 2004 | The British government announces that they have "re-interpreted" the law and are now declaring the sale of fresh psilocybin mushrooms a "preparation" and therefore illegal. Some shops close, but other remain open and some are shut down by police. Eventually charges are dropped and some shops remain open. | |
| Apr 7, 2005 | The British government passes a new Drugs Bill expanding police powers and explicitly making fresh mushrooms illegal. | |
| Jul 18, 2005 | New British ban on psilocybin mushrooms goes into effect. | |
| May 2006 | Survey results published in Neurology show that both psilocybin-containing mushrooms and LSD may reduce severity and frequency of cluster headaches. 12 [Details] | |
| Jul 11, 2006 | Research shows psilocybin can induce mystical experiences. 13 [More Info] [Details] |
