Psychoactive plants are natural species that contain compounds capable of altering an individual's mental state. These plants can affect mood, perception, and consciousness, often leading to experiences such as euphoria, hallucinations, or relaxation. Common examples include cannabis, psilocybin mushrooms, and peyote, each containing unique chemicals that interact with the brain. Many cultures have used psychoactive plants for centuries, often in religious or healing practices. These plants can be consumed in various forms, such as teas, extracts, or dried materials. Research into their effects has increased, leading to a better understanding of their potential therapeutic benefits and risks.
