Adrenochrome, chemical formula C9H9NO3, is a pigment obtained by the oxidation of adrenaline (epinephrine). Adrenochrome monosemicarbazone, also known as carbazochrome, is a hemostatic, meaning it reduces capillary bleeding.
Adrenochrome is synthesized in vivo by the oxidation of epinephrine. In vitro, silver oxide (Ag2O) is used as an oxidizing agent. Its presence is detected in solution by a pink color, and turns brown upon polymerization.
Adrenochrome is uncontrolled in the United States. This means it is generally considered legal to buy, possess, and distribute (sell, trade or give). If sold as a supplement, sales must conform to U.S. supplement laws. If sold for consumption as a food or drug, sales are regulated by the FDA.
Megavitamin therapy advocates Abram Hoffer and Humphry Osmond claimed that adrenochrome is a hallucinogenic substance and may be responsible for schizophrenia and other mental illnesses. In what they called the "adrenochrome hypothesis", they speculated that megadoses of vitamin C and niacin could cure schizophrenia by reducing brain adrenochrome. There has been controversy about whether adrenochrome can be classified as a psychotropic drug.
Author Hunter S. Thompson mentions adrenochrome in his book Fear and Loathing in Las Vegas. In the book it is derived from a living donor's adrenal gland (removing the gland kills the donor; it cannot be taken from a corpse). As such, it is purported to be very exotic, and very intense: "the first wave felt like a combination of mescaline and methedrine". Thompson reported a significant perceived rise in body temperature that led to paralysis. The adrenochrome scene also appears in the novel's film adaptation. In the DVD commentary, director Terry Gilliam admits that his and Thompson's portrayal is a fictional exaggeration. In fact, Gilliam insists that the drug is entirely fictional and seems unaware of the existence of a substance with even a similar name. Thompson also mentions the substance in his book Fear and Loathing on the Campaign Trail '72.
