A psychedelic experience is a temporary altered state of consciousness induced by the consumption of psychedelic drugs (such as LSD, mescaline, Salvia divinorum, psilocybin mushrooms, cannabis, and DMT). An acid trip refers to psychedelic experiences brought on by the use of LSD. The term “psychedelic” derives from Greek words meaning “mind revealing”. Psychedelic experiences are used in recreational, religious/mystical and therapeutic contexts.
