Psilocybe cubensis
Singer noted that Psilocybe cubensis had psychoactive properties in 1949.
In Australia, the use of psychoactive mushrooms grew rapidly between 1969 and 1975.
In a 1992 paper, locals and tourists in Thailand were reported to consume P. cubensis and related species in mushroom omelets—particularly in Ko Samui and Ko Pha-ngan. At times, omelets were adulterated with LSD, resulting in prolonged intoxication. A thriving subculture had developed in the region. Other localities, such as Hat Yai, Ko Samet, and Chiang Mai, also had some reported uغیر مجاز می باشدe.
In 1996, jars of honey containing Psilocybe cubensis were confiscated at the Dutch-German border. Upon examination, it was revealed that jars of honey containing psychedelic mushrooms were being sold at Dutch coffee shops.
P. cubensis is probably the most widely known of the psilocybin-containing mushrooms used for triggering psychedelic experiences after ingestion. Its major psychoactive compounds are:
Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine)
Psilocin (4-hydroxy-N,N-dimethyltryptamine)
Baeocystin (4-phosphoryloxy-N-methyltryptamine)
Norbaeocystin (4-phosphoryloxytryptamine)
Aeruginascin (N,N,N-trimethyl-4-phosphoryloxytryptamine)
The concentrations of psilocin and psilocybin, as determined by high-performance liquid chromatography, are in the range of 0.14–0.42% (wet weight) and 0.37–1.30% (dry weight) in the whole mushroom 0.17–0.78% (wet weight) and 0.44–1.35% (dry weight) in the cap, and 0.09%–0.30% (wet weight) and 0.05–1.27% (dry weight) in the stem, respectively.[17] For quickly and practically measuring the psychoactive contents of most healthy Psilocybe cubensis varieties, it can generally be assumed that there is approximately 15 mg (+/- 5 mg) of psilocybin per gram of dried mushroom.[18] Furthermore, due to factors such as age and storage method, the psilocybin and psilocin content of a given sample of mushrooms will vary.
Individual body composition, brain chemistry and psychological predisposition play a significant role in determining appropriate doses. For a modest psychedelic effect, a minimum of one gram of dried Psilocybe cubensis mushrooms is ingested orally, 0.25–1 gram is usually sufficient to produce a mild effect, 1–2.5 grams usually provides a moderate effect and 2.5 grams and higher usually produces strong effects.[19] For most people, 3.5 dried grams (1/8 oz) would be considered a high dose and may produce an intense experience; this is, however, typically considered a standard dose among recreational users. Body composition (usually weight) should be taken into account when calculating doغیر مجاز می باشدe. For many individuals, doses above three grams may be overwhelming. For a few rare people, doses as small as 0.25 gram can produce full-blown effects normally associated with very high doses. For most people, however, that dose level would have virtually no effects.
There are many different ways to ingest Psilocybe cubensis. Users may prefer to take them raw, freshly harvested, or dried and preserved. It is also possible to prepare culinary dishes such as pasta or tea with the mushrooms. However, the psychoactive compounds begin to break down rapidly at temperatures exceeding 100 °C (212 °F).[20] Another method of ingestion known as "Lemon Tekking" involves combining pulverized Psilocybe cubensis with a concentrated citrus juice with a pH of ~2. Many users believe that a considerable amount of the psilocybin will have been dephosphorylated into psilocin, the psychoactive metabolite, by citric acid. However, this claim is not substantiated by the literature on the metabolism of psilocybin, as dephosphorylation is known to be mediated by the enzyme alkaline phosphatase in humans.[21] It is therefore more likely that citric acid mostly helps in breakdown of mushroom cells, aiding in digestion and psilocybin release.[citation needed] The "Lemon Tekk" method of consumption results in a more rapid onset and can offer easier digestion or reduced "come-up pressure" associated with raw consumption.[22] Psilocybe cubensis can also be taken in conjunction with other botanicals such as turmeric, ginger, and black pepper. A 2019 study observed turmeric to act as a mild MAOI, which, when combined with psilocin, potentiates the biochemical interactions between serotonin receptors and psilocin, creating an entourage effect.
Upon ingestion, effects usually begin after approximately 20–60 minutes (depending on the method of ingestion and stomach contents) and may last from four to ten hours, depending on doغیر مجاز می باشدe and individual biochemistry. Visual distortions often occur, including walls that seem to breathe, a vivid enhancement of colors, and the animation of organic shapes.[citation needed]
The effects of high doses can be overwhelming depending on the particular phenotype of cubensis, grow method, and the individual. It is recommended not to eat wild mushrooms without properly identifying them as they may be poisonous. In particular, similar species include mushrooms of the genus Galerina and Pholiotina rugosa—all potentially deadly—and Chlorophyllum molybdites. All of these grow in pastures, a similar habitat to that preferred by P. cubensis.
