Amanita muscaria is noted for its hallucinogenic properties, with its main psychoactive constituents being the compounds ibotenic acid and muscimol. The mushroom was used as an intoxicant and entheogen by the peoples of Siberia and has a religious significance in these cultures. There has been much speculation on possible traditional use of this mushroom as an intoxicant in other places such as the Middle East, Eurasia, North America, and Scandinavia.
Amanita muscaria was widely used as an entheogen by many of the indigenous peoples of Siberia. Its use was known among almost all of the Uralic-speaking peoples of western Siberia and the Paleosiberian-speaking peoples of the Russian Far East. There are only isolated reports of A. muscaria use among the Tungusic and Turkic peoples of central Siberia and it is believed that on the whole entheogenic use of A. muscaria was not practiced by these peoples. In western Siberia, the use of A. muscaria was restricted to shamans, who used it as an alternative method of achieving a trance state. (Normally, Siberian shamans achieve trance by prolonged drumming and dancing.) In eastern Siberia, A. muscaria was used by both shamans and laypeople alike and was used recreationally as well as religiously. In eastern Siberia, the shaman would take the mushrooms, and others would drink his urine. This urine, still containing psychoactive elements, may be more potent than the A. muscaria mushrooms with fewer negative effects such as sweating and twitching, suggesting that the initial user may act as a screening filter for other components in the mushroom.
The Koryak of eastern Siberia have a story about the fly agaric (wapaq) which enabled Big Raven to carry a whale to its home. In the story, the deity Vahiyinin („Existence“) spat onto earth, and his spittle became the wapaq, and his saliva becomes the warts. After experiencing the power of the wapaq, Raven was so exhilarated that he told it to grow forever on earth so his children, the people, could learn from it. Among the Koryaks, one report said that the poor would consume the urine of the wealthy, who could afford to buy the mushrooms.
The wide range of psychoactive effects have been variously described as depressant, sedative-hypnotic, psychedelic, dissociative, and or deliriant; paradoxical effects such as stimulation may occur, however. Perceptual phenomena such as synesthesia, macropsia, and micropsia may occur; the latter two effects may occur simultaneously and or alternatingly as part of Alice in Wonderland syndrome, collectively known as dysmetropsia, along with related distortions pelopsia and teleopsia. Some users report lucid dreaming under the influence of its hypnotic effects. Unlike Psilocybe cubensis, A. muscaria cannot be commercially cultivated, due to its mycorrhizal relationship with the roots of pine trees
A fatal dose has been calculated as 15 caps.
Eat about 1 preferably dried (or fresh) mushroom or less to induce dreamlike visionary trance states. (Try microdosing first)
