Psilocybe Cubensis Thai

Psilocybin mushrooms are fungi that contain the psychoactive compounds psilocybin and psilocin. There are multiple colloquial terms for psilocybin mushrooms, the most common being shrooms and magic mushrooms. Biological genera containing psilocybin mushrooms include Agrocybe, Conocybe, Copelandia, Galerina, Gerronema, Gymnopilus, Hypholoma, Inocybe, Mycena, Panaeolus, Pluteus, and Psilocybe. There are approximately 190 species of psilocybin mushrooms and most of them fall in the genus Psilocybe.

Psilocybin mushrooms were used in ancient times, and were depicted in rock paintings. Many native peoples have used mushrooms for religious purposes, rituals and healing. In modern day society they are often used to evoke a "high", which is sometimes described as spiritual experience and is often euphoric in nature. Sometimes however, the disorientation of psilocybin and psilocin's psychedelic effects may bring on anxiety such as panic attacks, depression and paranoid delusions.^{[citation needed]} However, recent studies done at the Imperial College of London and also at John Hopkins School of Medicine conclude that when used properly, Psilocybin acts as an anti-depressant as proven by fMRI brain scans.

Psilocin (4-HO-DMT), an aromatic compound, sometimes also (mis)spelled psilocine, psilocyn, or psilotsin, is a psychedelic mushroom alkaloid. It is found in most psychedelic mushrooms together with its phosphorylated counterpart psilocybin. Psilocin is a Schedule I drug under the Convention on Psychotropic Substances. The mind-altering effects of psilocin are highly variable and subjective, but resemble those caused by LSD and mescaline. The effects typically last anywhere from three to eight hours depending on certain variables (such as metabolism, food interaction); however the effects can seem to last much longer due to psilocin's ability to distort the perception of time.

Psilocybin ( /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 to those of LSD and mescaline. The effects generally 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.

Psilocybe is a genus of small mushrooms growing worldwide. This genus is best known for its species with psychedelic or hallucinogenic properties, widely known as "magic mushrooms", though the majority of species do not contain hallucinogenic compounds. Psilocin and psilocybin are the hallucinogenic compounds responsible for the psychoactive effects of many species in the genus.

The word Psilocybe comes from the Greek words ψιλός + κύβη, and literally means "bare headed", referring to the mushroom's detachable pellicle (loose skin over the cap). It may be pronounced with the accent on the first syllable (/ˈsɪlɵsaɪbiː/, US dict: sĭl′·ə·sī·bē) or the second (/saɪˈlɒsəbiː/, US dict: sī·lŏs′·ə·bē). The final e is not silent. The marked difference between the Botanical Latin-based pronunciation (given here) and anglicized colloquial pronunciations (with a silent "e") is sometimes a source of confusion in oral communication about this genus.

A psychoactive drug, psychopharmaceutical, or psychotropic is a chemical substance that crosses the blood–brain barrier and acts primarily upon the central nervous system where it affects brain function, resulting in changes in perception, mood, consciousness, cognition, and behavior. These substances may be used recreationally, to purposefully alter one's consciousness, as entheogens, for ritual, spiritual, and/or shamanic purposes, as a tool for studying or augmenting the mind, or therapeutically as medication.

Because psychoactive substances bring about subjective changes in consciousness and mood that the user may find pleasant (e.g. euphoria) or advantageous (e.g. increased alertness), many psychoactive substances are abused, that is, used excessively, despite health risks or negative consequences. With sustained use of some substances, psychological and physical dependence ("addiction") may develop, making the cycle of abuse even more difficult to interrupt. Drug rehabilitation aims to break this cycle of dependency, through a combination of psychotherapy, support groups and even other psychoactive substances such as acamprosate or naltrexone in the treatment of alcoholism, or methadone or buprenorphine maintenance therapy in the case of opioid dependency. However, the reverse is also true in some cases, that is certain experiences on drugs may be so unfriendly and uncomforting that the user may never want to try the substance again. This is especially true of the deliriants (e.g. Jimson weed) and powerful dissociatives (e.g. Salvia divinorum). Most purely psychedelic drugs are considered to be non-addictive (LSD, psilocybin, mescaline etc.); "psychedelic amphetamines" (such as MDA, MDMA etc.) may produce an additional stimulant and/or euphoriant effect, and thus have an addiction potential.

Psilocybe cubensis is a species of psychedelic mushroom whose principal active compounds are psilocybin and psilocin. Commonly called Boomers, Cubes or Gold Caps, it belongs to the Strophariaceae family of fungi and was previously known as Stropharia cubensis.
