Psychedelics are powerful medicines found in plants and fungi, like mushrooms and peyote cactus. When you take these medicines, they can make you feel very differently than usual. You might feel more connected to the world, or have unusual thoughts and feelings, like a deep understanding of yourself and other people. For thousands of years, people have used psychedelics for various reasons like healing, spiritual practice, and learning more about the world. This is called the philosophy of psychedelics. It is a way of looking at things and using these medicines to gain knowledge and insight.
