Jurisdictions that have specifically enacted or amended laws to criminalize the possession of psilocybin mushroom spores include Germany (since 1998), <.span>and California, Georgia, and Idaho in the United St`tes.
However these mushrooms are different in a few ways.  A cross-tolerance can develop between psilocybin and the pharmacologically similar LSD, and between psilocybin and phenethylamines such as mescaline and DOM. 5.6 milligrams of psilocybin per gram of dried material and 0.15 milligrams of psilocyn per gram of dried material So I would say about 9 grams of stuntzii to equal 2 grams cubenis=] The nicknames “blue legs” and “blue ringers” arise from the significant bluing reaction this species undergoes in response to handling or age. Psilocybe stuntzii is a rare mushroom originally found on the campus of the University of Washington in the USA.  However, the neurochemical basis of psilocybin’s effects on the perception of time are not known with certainty. However, in the Psychedelics Encyclopedia, author Peter Stafford noted, “The psilocybin experience seems to be warmer, not as forceful and less isolating. Unfortunately, though, they apparently taste very bitter. In the United States, laws were passed in 1966 that prohibited the production, trade, or ingestion of hallucinogenic drugs; Sandoz stopped producing LSD and psilocybin the same year. She’s the author of “Your Psilocybin Mushroom Companion: An Informative, Easy-to-Use Guide to Understanding Magic Mushrooms”, writes a column for Playboy about psychedelics and cannabis and has also contributed to High Times, Herb, Rolling Stone and Teen Vogue. Although most of the remaining drug is eliminated in this way within 8 hours, it is still detectable in the urine after 7 days.  It was originally identified growing on the University of Washington campus.
Read: Will Shroom Dispensaries Become a Thing Anytime Soon? , A possible biosynthetic route to psilocybin. ( Log Out / However, you can find cubensis growing throughout the southern US, into Mexico, Central American and South America. Hofmann’s employer Sandoz marketed and sold pure psilocybin to physicians and clinicians worldwide for use in psychedelic psychotherapy. Synonyms and alternate spellings include: 4-PO-DMT (PO: The academic communities’ approval for the methodology employed is exemplified by the quartet of commentaries published in the journal. Home » Uncategorized » Psilocybin, псилоцибин , بسيلوسيبين , 赛洛西宾 . Ingesting psilocybin in combination with other drugs, including alcohol, can also increase the likelihood of a bad trip. A typical recreational dosage is 10–50 mg psilocybin, which is roughly equivalent to 10–50 grams of fresh mushrooms, or 1–5 grams of dried mushrooms. Copelandia cyanescens prefer to live in dung in pastures and fields in warmer, subtropical climates. , Repeated use of psilocybin does not lead to physical dependence.  One of the participants was religious scholar Huston Smith, author of several textbooks on comparative religion; he later described his experience as “the most powerful cosmic homecoming I have ever experienced.” In a 25-year followup to the experiment, all of the subjects given psilocybin described their experience as having elements of “a genuine mystical nature and characterized it as one of the high points of their spiritual life”. Liberty caps, also known as Witch’s Hats, grow wildly all over the Northern Hemisphere. P. mexicana is also the species that French botanist Roger Heim sent to Albert Hoffman in 1958. This species is still wildly popular and abundant, especially in England, where the first report of a family tripping out on them appeared in print: In London, 1799, a family reportedly picked and ate wild mushrooms growing in Green Park, which caused one son to laugh uncontrollably, the father to believe he was dying, and most family members to have vertigo.
, Common responses include: pupil dilation (93%); changes in heart rate (100%), including increases (56%), decreases (13%), and variable responses (31%); changes in blood pressure (84%), including hypotension (34%), hypertension (28%), and general instability (22%); changes in stretch reflex (86%), including increases (80%) and decreases (6%); nausea (44%); tremor (25%); and dysmetria (16%) (inability to properly direct or limit motions). It is in the section Stuntzae, other members of the section include Psilocybe caeruleoannulata, Psilocybe meridionalis, Psilocybe mescaleroensis, Psilocybe ovoideocystidiata, Psilocybe rostrata, Psilocybe subaeruginascens, Psilocybe subaeruginascens var.
Liberty caps are small and can blend in with the grass because their stems are only 40 to 100 mm (1.5 to 4 in) long. Several websites[nb 6] emerged that have contributed to the accessibility of information on description, use, effects and exchange of experiences among users.  At higher doses, psilocybin can lead to “Intensification of affective responses, enhanced ability for introspection, regression to primitive and childlike thinking, and activation of vivid memory traces with pronounced emotional undertones”. They’re a good introduction to magic mushrooms for this reason, but can also be a disappointment to those with Psilocybe cubensis experience who travel to Mexico to try them.  Its pKa values are estimated to be 1.3 and 6.5 for the two successive phosphate OH groups and 10.4 for the dimethylamine nitrogen, so in general it exists as a zwitterionic structure. These negative effects were reported to be easily managed by the researchers and did not have a lasting negative effect on the subject’s sense of well-being. Conversely, smaller groups (fewer than six individuals) were seen as more supportive. Derrumbes are small, with stems ranging from 40 to 120 mm (1.5 to 4 in), and have a silvery-blue metallic luster that makes them easy to differentiate from other species, according to Psillow.
The drug reacts in the Marquis test to produce a yellow color, and a green color in the Mandelin test.  Various lines of evidence have shown that interactions with non-5-HT2 receptors also contribute to the subjective and behavioral effects of the drug.  Exposure to light is detrimental to the stability of aqueous solutions of psilocybin, and will cause it to rapidly oxidize—an important consideration when using it as an analytical standard. The spores of these mushrooms do not contain psilocybin or psilocin. , Psilocybin (O-phosphoryl-4-hydroxy-N,N–dimethyltryptamine, 4-PO-Psilocin, or 4-PO-HO-DMT) is a prodrug that is converted into the pharmacologically active compound psilocin in the body by a dephosphorylation reaction.  Also known as Psilocybe pugetensis. An analysis of information from the National Survey on Drug Use and Health showed that the use of psychedelic drugs such as psilocybin is associated with significantly reduced odds of past month psychological distress, past year suicidal thinking, past year suicidal planning, and past year suicide attempt. 10) Blue Ringers (Psilocybe Stuntzii) You can find this one growing in clusters on wood chips, soil rich in woody debri, newly placed lawns and fields, along roads/paths and in gardens. Isotopic labeling experiments suggest that tryptophan decarboxylation is the initial biosynthetic step and that O-phosphorylation is the final step.  In both cases, psychotic symptoms are thought to arise from a “deficient gating of sensory and cognitive information” in the brain that ultimately lead to “cognitive fragmentation and psychosis”. Identified in 1838, P. semilanceata was the first psilocybin mushroom native to Europe to be formally recognized. Magic mushrooms are so incredible and mysterious, from the beautiful experiences they occasion to the mystical compounds that they naturally produce. The species is common at altitudes between 1000 and 1800 meters (3280 to 5900 feet), and prefers to live in moss, meadows, deciduous forests, and soils rich in manure, as well as alongside roads and trails—but never directly on dung. Psilocin has a high affinity for the 5-HT2B and 5-HT2C receptors in the human brain, and with a slightly lower affinity for the 5-HT2A receptor. The experience of magic truffles in comparison to other psilocybin-containing mushrooms is said to be very similar, but depending on the dose, somewhat less intense.
He has good knowledge of IPM, GMP, Regulatory aspects, he has several International patents published worldwide .
In Mexico today they’re often called “Pajaritos” meaning “little birds” for packing such a potent experience into such a small, fragile mushroom.
“Although widely distributed, P. caerulipes is not found frequently,” writes Stamets.  In rare cases people have injected mushroom extracts intravenously.
