Psilocybin or magic mushrooms are naturally occurring and are consumed for their hallucinogenic effects. They belong to a group of drugs known as hallucinogens (also known as psychedelics). The key ingredient found in magic mushrooms is psilocybin. When psilocybin is taken, it is converted in the body to psilocin, which is the chemical with the psychoactive properties.1
