Magic mushrooms are mushrooms that contain psilocybin and psilocin. These substances are hallucinogens and have been used by people for thousands of years. There are over 75 subtropical species of magic mushrooms. Since many species look alike it can be hard to tell them apart. The two compounds in magic mushrooms (psilocybin and psilocin) are hallucinogen, thus consuming them will provide an altered state of consciousness to the consumer.
