Substance info: Amanitas Muscaria


The most common psychoactive amanita mushrooms are the striking fly-agaric (Amanita muscaria) and the panther mushroom (A. pantherina). Both contain the ibotenic acid and muscimol, which produce inebriating effects. Amanita intoxication is quite different from that caused by psychedelic psilocybin mushrooms, which are primarily found in the Psilocybe genus. The effects of amanitas are sometimes considered unpleasant, and are often accompanied by nausea, chills, and other negative side effects.

Amanita muscaria mushrooms have been used in Siberian shamanism for centuries, or perhaps as long as thousands of years. Some authors have speculated that the mushroom could be associated with other historical and cultural phenomena such as the mysterious magical plant "Soma” described in early Hindu scriptures.

Note: be careful if you wanna pick it up in the wild. Amanitas muscaria is part of one of the deadliest mushrooms family - do not eat it unless you know what you are doing.

Dose

Amanita muscaria: Recreational doses range from 3-10 grams of dry mushroom material depending on the strength of the specimen. Fresh mushrooms are considerably heavier. One medium-size cap of an Amanita muscaria is sometimes considered a moderate dose, but potency varies widely, depending on the season in which they are picked and significant regional variations.

Amanita pantherina: In North America the average potency of the A. pantherina is greater than that of the A. muscaria. Data is limited, but Ott reports that approximately one-half cup of sauteed material was a strong dose. [Ott J. Pharmacotheon. Natural Products Co. 1996. pg. 339]

Price

Dried Amanita muscaria averages around $20-$30 per ounce on ethnobotanical vendor web sites. Psychoactive amanitas are rarely found in underground markets.

Law

Amanita mushrooms and their active ingredients are uncontrolled in the United States and in most countries. If sold for consumption as a food or drug, sales are regulated by the FDA in the US.

Chemistry

The primary effects of amanitas come from ibotenic acid and muscimol. Muscimol affects the GABA system, while ibotenic acid simulates glutamate in the brain. When baked or dried, ibotenic acid transforms into the more-potent muscimol through decarboxylation.

The alkaloid muscarine was believed to be the primary psychoactive agent in A. muscaria for nearly a century, but it usually occurs in amounts that are too small to have an effect. Muscarine contributes to some of the negative side effects such as increased sweating and salivating.

Production

Psychoactive amanitas grow wild across the United States and throughout the northern hemisphere. They are sometimes sold by ethnobotanical vendors or at head shops, but remain relatively uncommon. A. muscaria has a mycorrhizal (symbiotic) relationship with coniferous trees. Attempts to cultivate A. muscaria separate from coniferous tress have been largeley unsuccessful.

History

Amanita muscaria mushrooms have a long history of shamanic use in some parts of Siberia. possibly dating back thousands of years. The earliest-known documented account of Siberian mushroom use dates to 1658 when a Polish prisoner-of-war wrote "They eat certain fungi in the shape of fly-agarics, and thus they become drunk worse than on vodka, and for them that's the very best banquet."

Controversial theories have been advanced about other possible historical uses of psychoactive amanitas. Most famously, R. Gordon Wasson argued in his book Soma that the A. muscaria was an entheogenic sacrament described by early Hindus in the Rig Veda.

Effects

The potency and effects of amanitas vary widely among individuals and among mushroom specimens. Strong nausea and/or vomiting are common, particularly in the first few hours. Some users report euphoria and a sociable feeling of inebriation with some similarities to alcohol intoxication. Users may experience mild visual distortions, loss of balance, and sedation. Some report feeling a sense of internal clarity, while others feel disoriented or confused.

Onset

Onset is generally slow, typically taking two to three hours.

Duration

The primary effects of amanitas last for 6-8 hours when taken orally.

Positive effects

Euphoria: feelings of peace and well being, marked analgesia (pain relief), physical relaxation / dream state: (during the sedative effects) can be highly detailed, colorful, and have a great sense of clarity and lucidity. Some people describe these as being similar to Lucid Dreaming. Some describe them as Out of Body Experiences (OOBEs). As with normal dreams, the Amanita Dream State can consist of a wide variety of experiences.
Internal dialogue: some people report a strong sense of an internal discussion, a feeling of being able to think through personal issues. Others report a significant reduction of internal dialogue, sense of peacefulness, and internal quiet.

Synesthesia: is somewhat common, smelling words, tasting colors, etc. clarity: Often no interference with memory or logic: many report strong "clarity of thought" and "stillness of mind". Others report mild to strong confusion. Internal focus: Difficulty in focusing concentration on external tasks. Increased focus on internal imagination, imagery, day dreams.
Sociability: Group interaction can become incoherent: "conversational weirdness", frequent changes in topic, "non-linear conversations" . Sexual feelings: Some people report increased sexual feelings, others report very unsexual emotional and sensual distance / coldness.

Risks

There are a handful of deaths attributed to A. muscaria, but this appears to be extremely uncommon. A. muscaria and A. pantherina are frequently described as "toxic" in mushroom field guides, but this appears to refers to the putative undesirability of their psychoactive effects.
Psychoactive amanitas are not cultivated, and must be gathered in the wild. While the Amanita muscaria is distinctive in appearance, possessing a striking red cap, it is possible to confuse it for other species such as A. regalis or A. caesarea, which are non-psychoactive. Other mushrooms in the Amanita genus are deadly poisonous: the Destroying Angel (A. virosa) and Death Cap (A. phalloides) are two of the deadliest mushrooms known. The deadly amanitas found in North America have white or greenish caps. Wild mushroom gathering is not safe if you do not know what you're doing.

Many people experience nausea and/or vomiting during amanitas experiences, especially during the first few hours. Drying or cooking amanitas prior to consumption appears to reduce nausea. Other common negative effects include muscle twitching and increased salivation or sweating.
The mental effects of amanitas are sometimes described as disturbing or disorienting. There are reports of individuals harming themselves under their influence

Addiction potential

Psychoactive Amanitas are neither physically addicting nor likely to cause psychological dependence.
