The majority of adverse physical effects or negative psychological reactions produced by "magic mushrooms" generally result from inappropriate set and expectation, or because of improper dosage, which may vary considerably among consumers, different mushroom species, or even within an individual species. The question of dosage is often confused by the variation in the source of the hallucinogenic mushroom species which is consumed. For example, Psilocybe cubensis, when picked and eaten from its natural dung (manure) habitat, produces a relatively mild mindaltering experience, which is evident from the large amounts of fresh specimens needed to achieve a threshold experience. However when grown in vitro (indoor laboratory cultivation and/or illicit cultivation), Psilocybe cubensis apparently can produce a more potent strain capable of inducing a very intense visual, sometimes quite disturbing, experience. This dosage assumes that the consumption of 1 to 3 gm of dried material would be too low if the mushroom specimen came from a wild source. This low potency for Psilocybe cubensis has been confirmed by research scientists Margot & Watling, (1981), who were surprised by the comparatively small amounts of psilocybin and psilocin which they extracted from wild specimens collected from five different locations in Australia. This suggests that a much larger dose would be required to produce significant hallucinations. It is possible that the chemicals most likely degenerated between the time that they were harvested and the time of analysis. However, it should be noted that a strain of Psilocybe cubensis producing different flushes (harvests) will vary somewhat in potency between flushes.The first livestock to arrive in Australia were brought from the Cape of Good Hope in

several members of a family eat the mushrooms together: it is not uncommon for a father, mother, children, uncles, and aunts to all participate in these transformations of the mind that elevate consciousness onto a higher plan. The kinship relation is thus the basis of the transcendental subjectivity that Husserl said is intersubjectivity. The mushrooms themselves are eaten in pairs, a couple representing man and woman that symbolizes the dual principle of procreation and creation. Then they sit together in their inner light, dream and realize and converse with each other, presences seated there together, their bodies immaterialized by the blackness, voices from without their communality. In a general sense, for everyone present the purpose of the session is a therapeutic catharsis. The chemicals of transformation of revelation that open the circuits of light, vision, and communication, called by us mind-manifesting, were known to the American Indians as medicines: the means given to men to know and to heal, to see and to say the truth. Among the Mazatecs, many, one time or another during their lives, have eaten the mushrooms, whether to cure themselves of an ailment or to resolve a problem; but it is not everyone who has a predilection for such extreme and arduous experiences of the creative imagination or who would want to repeat such journeys into the strange, unknown depths of the brain very frequently: those who do are the shamans, the masters, whose vocation it is to eat the mushrooms because they are the men of the spirit, the men of language, the men of wisdom. They are individuals recognized by their people to be expert in such psychological adventures, and when the others eat the mushrooms they always call to be with them, as a guide, one of those who is considered to be particularly acquainted with these modalities of the spirit. The medicine man presides over the session, for just as the Mazatec family is paternal and authoritarian, the liberating experience unfolds in the authoritarian context of a situation in which, rather than being allowed to speak or encouraged to express themselves, everyone is enjoined to keep silent and listen while the shaman speaks for each of those who are present. As one of the early Spanish chroniclers of the New World said: "They pay a sorcerer who eats them the mushrooms and tells them what they have taught him. He does so by means of a rhythmic chant in full voice."Mind-altering (psilocybine containing) mushrooms have been traditionally used in religious healing and curing ceremonies by nativeThose who ingest Copelandia cyanescens, known in
The question of dosage is often confused by the variation in the source of the hallucinogenic mushroom species which is consumed.Existing evidence indicates that man in the Old World —Europe, Asia, Africa, and Australia—has made less use of native plants and shrubs for their hallucinogenic properties than has man in the New World. There is little reason to believe that the vegetation of one half of the globe is poorer or richer in species with hallucinogenic properties than the other half. Why, then, should there be such disparity? Has man in the Old World simply not discovered many of the native hallucinogenic plants? Are some of them too toxic in other ways to be utilized? Or has man in the Old World been culturally less interested in narcotics? We have no real answer. But we do know that the Old World has fewer known species employed hallucinogenically than does the New World: compared with only 15 or 20 species used in the Eastern Hemisphere, the species used hallucinogenically in the Western Hemisphere number more than 100! Yet some of the Old World hallucinogens today hold places of primacy throughout the world. Cannabis, undoubtedly the most widespread of all the hallucinogens, is perhaps the best example. The several solanaceous ingredients of medieval witches' brews—henbane, nightshade, belladonna, and mandrake—greatly influenced European philosophy, medicine, and even history for many years. Some played an extraordinarily vital religious role in the early Aryan cultures of northern India. The role of hallucinogens in the cultural and social development of many areas of the Old World is only now being investigated. At every turn, its exte Most recreational users of Psilocybe cubensis (when grown in vitro) require a dosage of 1 to 2 gm of dried mushrooms to produce an altered state of consciousness; a clinical dosage for Psilocybe cubensis, on the other hand, had previously been reported as ranging from 3 to 5 gm of dried material. This dosage would be comparable to the amount of fungal material consumed for religious purposes in a Mazatec Indian healing and curing ceremony. In 1982, one research team "found that the level of psilocybin and psilocin varies over a factor of 4 among various in vitro cultures of Psilocybe cubensis, while specimens from outdoors varied tenfold." A fresh dosage of Psilocybe cubensis in Australia would be approximately from 1 to 2 large mushrooms weighing up to as much as one fresh ounce, or as many as from 25 to 50 small mushrooms equaling the same weight amount. Ethnopharmacologist Jonathan Ott (1976, 1993) noted that he has observed "the ingestion of from 0.5 gm to 5.9 gm dried weight (10 gm to 40 gm fresh)", of various species of Psilocybe. Dosage for Psilocybe subcubensis would be the same as for Psilocybe cubensis. Both of these latter two species are macroscopically alike. The usual dosage for Copelandia cyanescens required to induce psychedelic visual effects ranges from 1 to 3 large specimens (cap diameter c. 5 mm), or as many as 5 to l0 medium-sized mushrooms (cap diameter c. 2.5 mm); however, personal tolerance to this species may occur with continued use, and some who consume large amounts of this mushroom have reportedly ingested as many as 50 to 200 fresh specimens of various sizes.
