Entheogen
A group of peyotes, in cultivation. Peyote has been used in ritual contexts for thousands of years.[1][2][3] With the advent of organic chemistry, there now exist many synthetic drugs with similar psychoactive properties, many derived from these plants. Etymology[edit] The neologism entheogen was coined in 1979 by a group of ethnobotanists and scholars of mythology (Carl A. Entheogen was coined as a replacement for the terms hallucinogen and psychedelic. Ruck et al. argued that the term hallucinogen was inappropriate owing to its etymological relationship to words relating to delirium and insanity. In a strict sense, only those vision-producing drugs that can be shown to have figured in shamanic or religious rites would be designated entheogens, but in a looser sense, the term could also be applied to other drugs, both natural and artificial, that induce alterations of consciousness similar to those documented for ritual ingestion of traditional entheogens. Entheogens[edit] Species[edit]
Salvinorin A
Salvinorin A is the main active psychotropic molecule in Salvia divinorum, a Mexican plant which has a long history of use as an entheogen by indigenous Mazatec shamans. Salvinorin A is considered a dissociative exhibiting atypically psychedelic effects. Salvinorin A can produce psychoactive experiences in humans with a typical duration of action being several minutes to an hour or so, depending on the method of ingestion.[2] History[edit] Salvinorin A was first described and named in 1982 by Alfredo Ortega and colleagues in Mexico. Pharmacology[edit] Potency and selectivity[edit] Salvinorin A is unique in that it is the only naturally occurring substance known to induce a visionary state via this mode of action; there are synthetic kappa-opioid agonists, (e.g. enadoline, ketazocine, pentazocine and relatives), which show similar hallucinatory and dissociative effects.

Tetrahydrocannabinol
Tetrahydrocannabinol (THC), or more precisely its main isomer (−)-trans-Δ9-tetrahydrocannabinol ( (6aR,10aR)-delta-9-tetrahydrocannabinol), is the principal psychoactive constituent (or cannabinoid) of the cannabis plant. First isolated in 1964, in its pure form, by Israeli scientists Raphael Mechoulam and Yechiel Gaoni at the Weizmann Institute of Science,[8][9][10] it is a glassy solid when cold, and becomes viscous and sticky if warmed. A pharmaceutical formulation of (−)-trans-Δ9-tetrahydrocannabinol, known by its INN dronabinol, is available by prescription in the U.S. and Canada under the brand name Marinol. An aromatic terpenoid, THC has a very low solubility in water, but good solubility in most organic solvents, specifically lipids and alcohols.[6] Tetrahydrocannabinol with double bond isomers and their stereoisomers is one of only three cannabinoids scheduled by Convention on Psychotropic Substances (the other two are dimethylheptylpyran and parahexyl).

Endocrine system
In addition to the specialised endocrine organs mentioned above, many other organs that are part of other body systems, such as bone, kidney, liver, heart and gonads, have secondary endocrine functions. For example the kidney secretes endocrine hormones such as erythropoietin and renin. A number of glands that signal each other in sequence are usually referred to as an axis, for example, the hypothalamic-pituitary-adrenal axis. As opposed to endocrine factors that travel considerably longer distances via the circulatory system, other signaling molecules, such as paracrine factors involved in paracrine signalling diffuse over a relatively short distance. The word endocrine derives from the Greek words ἐνδο- endo- "inside, within," and κρίνειν krinein "to separate, distinguish".

Ibogaine
Ibogaine is a naturally occurring psychoactive substance found in plants in the Apocynaceae family such as Tabernanthe iboga, Voacanga africana and Tabernaemontana undulata. A psychedelic with dissociative properties, the substance is banned in some countries; in other countries it is used by proponents of psychedelic therapy to treat addiction to methadone, heroin, alcohol, cocaine, methamphetamine, anabolic steroids, and other drugs. Ibogaine is also used to treat depression and post traumatic stress disorder. Ibogaine-containing preparations are used for medicinal and ritual purposes within African spiritual traditions of the Bwiti, who claim to have learned it from the Pygmy peoples. Ibogaine is an indole alkaloid that is obtained either by extraction from the iboga plant or by semi-synthesis from the precursor compound voacangine,[3][4] another plant alkaloid. History[edit] An ibogaine research project was funded by the US National Institute on Drug Abuse in the 1990s.
Psilocybin
Psilocybin[nb 1] (/ˌsɪləˈsaɪbɪn/ SIL-ə-SY-bin) is a naturally occurring psychedelic compound produced by more than 200 species of mushrooms, collectively known as psilocybin mushrooms. The most potent are members of the genus Psilocybe, such as P. azurescens, P. semilanceata, and P. cyanescens, but psilocybin has also been isolated from about a dozen other genera. As a prodrug, psilocybin is quickly converted by the body to psilocin, which has mind-altering effects similar (in some aspects) to those of LSD, mescaline, and DMT. In general, the effects include euphoria, visual and mental hallucinations, changes in perception, a distorted sense of time, and spiritual experiences, and can include possible adverse reactions such as nausea and panic attacks. History[edit] Early[edit] Modern[edit] Albert Hofmann (shown here in 1993) purified psilocybin and psilocin from Psilocybe mexicana in the late 1950s. Occurrence[edit]
PiHKAL
The book is arranged into two parts: A fictionalized autobiography of the couple.Detailed synthesis instructions for 179 different psychedelic compounds (most of which Shulgin discovered himself), including bioassays, dosages, and other commentary. The second part was made freely available by Shulgin on Erowid.org while the first part is available only in the printed text. Shulgin's choices of synthesis procedures in the second half of the book are themselves perhaps a small act of subversion: while the reactions are beyond the ability of people with a basic chemistry education, some tend to emphasize techniques that do not require difficult to obtain chemicals. Impact & popularity[edit] Through PIHKAL (and later TIHKAL), Shulgin sought to ensure that his discoveries would escape the limits of professional research labs and find their way to the public; a goal consistent with his stated beliefs that psychedelic drugs can be valuable tools for self-exploration.
