A fly agaric trip is an intoxication with ibotenic acid and muscimol, two compounds that act on the brain's glutamate and GABA systems. It has little in common with a psilocybin trip. People describe nausea and sweating in the first hour, then a dreamlike, drowsy state with distorted sizes and sounds, sometimes confusion and muscle twitching, often a long sleep. How strong it gets is hard to predict, because the amount of active compound differs from one mushroom to the next.
This site explains the mushroom itself, the chemistry, what published reports and poison centre records say about the experience, and the law in the countries our readers ask about. It does not tell you how to find, prepare or take it, and it never will: the mushroom that looks most like a harmless one in a photo can be a death cap.
Four numbers to start with
- 34 cases in fifteen years at one US regional poison centre, five of them needing a breathing tube, none fatal (poison centre data).
- 180 illnesses and 73 hospital admissions in the 2024 US outbreak linked to "mushroom" sweets, some of which contained muscimol (effects).
- 1 December 2008 is when fly agaric and panther cap went onto List II of the Dutch Opium Act (legal status).
- 6 to 12 hours is the typical delay before a death cap causes its first symptoms, long after the mistake (look-alikes).
Where to read next
The trip reports are composites built from recurring patterns in published accounts, including the unpleasant ones. Muscimol and ibotenic acid explains why the experience feels so different from magic mushrooms. The fly agaric page covers the species, Siberian accounts and the soma hypothesis, and about this site explains who publishes it.
