Psilocybin and psilocyn are the hallucinogenic principles contained in certain mushrooms. These “magic” mushrooms are generally grown in Mexico and Central America and have been used in native rituals for thousands of years. Psilocybin is structurally similar to serotonin, and produces its effects by disrupting normal functioning of the serotonin system.

How are they used?
Mushrooms can be eaten, brewed and consumed as tea.
What are their short-term effects?
Once ingested, mushrooms generally cause feelings of nausea before the desired mental effects appear. The high from using magic mushrooms is mild and may cause altered feelings and distorted perceptions of touch, sight, sound and taste. Other effects can include nervousness and paranoia. Effects can be different during each use due to varying potency, the amount ingested, and the user’s expectations, mood, surroundings, and frame of mind. On some trips, users experience sensations that are enjoyable. Others can include terrifying thoughts, and anxiety, fears of insanity, death, or losing control.
What are its long-term effects?
Some magic mushroom users experience “flashbacks”, or hallucinogen persisting perception disorder (HPPD), which are reoccurrences of hallucinations long after ingesting the drug. The causes of these effects, which in some users occur after a single experience with the drug, are not known.
