Entheogens are substances, often derived from plants or fungi, that are used in spiritual or religious contexts to induce altered states of consciousness. These substances can facilitate profound experiences, insights, or connections to the divine, and have been utilized in various cultures for centuries. Common examples include psilocybin mushrooms, peyote, and ayahuasca. The use of entheogens is often associated with rituals and ceremonies, where they play a role in healing, self-discovery, or community bonding. While some people seek these experiences for personal growth, others may use them in traditional practices guided by experienced shamans or spiritual leaders.
