Stories, Facts & Myths

What exactly is psilocybin, and why has it become such a big topic? Understanding the facts helps you cut through all the noise and mixed messages.

What is it?

Psilocybin is a naturally occurring psychedelic substance that is consumed for its hallucinogenic effects.

Psilocybin is one substance within a group of other substances, often called ‘psychedelics’ or psychedelic drugs.

The main ingredient in “magic mushrooms” is psilocybin. When psilocybin is taken, it is converted in the body to psilocin, which is the chemical with psychoactive properties. This drug is derived from a plant and targets specific centers of the brain to alter the understanding of sensory input. Psilocybin is in a class of psychoactive substances that produce changes in perception, mood, and cognitive processes.

Where does it come from?

Psilocybin can be found in natural environments usually dried out, rust in color with hints of white. It can also be found fresh - with a dark brown fan, light brown tops, and whitish-gray stems. These mushrooms look similar to ‘regular’ mushrooms found in nature and/or grocery stores in their appearance. They also can be found in trees, vines, seeds, fungi, and leaves.They can also come as dried material in capsules. Synthetic psilocybin appears as a white crystalline powder that can be processed into tablets or capsules or dissolved in water1.

Psychedelics have been used for many years by a diverse range of cultures and religions. Psilocybin can be found in Central America, Mexico, and the United States. Psilocybin is ingested orally (in tea or other foods) in many other cultures.1

What does it do?

Psychedelic experiences feature changes in normal perception such as visual distortions. These alterations may include: visual hallucinations, out-of-body experiences, and dissociation - where parts of the brain feel as though they aren’t connected through memories, behaviors, and feelings.

  • euphoria
  • change in consciousness, mood, thought and perception (commonly referred to as a ‘trip’ or ‘tripping’)
  • dilation of pupils
  • perceptual changes, such as visual and auditory hallucinations (seeing or hearing things that aren’t there, or that are distorted)
  • stomach discomfort and nausea
  • headaches
  • fast or irregular heartbeat
  • increased body temperature
  • breathing quickly
  • vomiting
  • facial flushes, sweating and/or chills1,2

Using psilocybin can also lead to a ‘bad trip’ which might include:

  • unpleasant or intense hallucinations
  • anxiety
  • paranoia
  • panic or fear1,2

  • stress
  • fatigue
  • anxiety and/or depression
  • decreased motivation
  • possible development of schizophrenia, psychosis and/or other mental health disturbances
  • flashbacks1,2,3
What are the risks?
Psilocybin + the brain

“Psilocybin activates serotonin receptors on brain cells in a way that reduces the energy needed for the brain to switch between different activity states”3. This can lead to permanent changes in the receptors and producers of chemicals in the brain. After a long period of use, receptors no longer generate neurotransmitters such as serotonin and this can lead to permanent damage of the synaptic gaps where it is received. Psilocybin may cause hallucinations, which may lead to an individual having difficulty distinguishing thoughts and fantasies from reality.

Some people who regularly use magic mushrooms may experience flashbacks involving a previous magic mushroom experience. They are usually visual distortions that involve changes in your emotions or perception.

Flashbacks can happen weeks, months or even years after the drug was last taken. This can be disturbing, especially if a frightening experience or hallucination is recalled. Flashbacks can be brought on by using other drugs, stress, tiredness or exercise and usually last a minute or two.

Is it legal?
  • The use, possession, or distribution of psilocybin is iIllegal for anyone under the age of 21.
  • Psilocybin is a Schedule I substance under the Controlled Substances Act.
  • Colorado recently passed legislation (Proposition 122) which has decriminalized psilocybin for adults aged 21 and over. However, there are many factors and limitations related to this legislation. * Decriminalization is the act of removing criminal sanctions against an act, article, or behavior. Decriminalization of psilocybin means it would remain illegal, but the legal system would not prosecute a person for possession under a specified amount and.or other specification.
