Psychedelics

A psychedelic substance is a psychoactive drug whose primary action is to alter the cognition and perception  of the mind. Psychedelics are part of a wider class of psychoactive drugs known as hallucinogens, which also includes related substances such as dissociatives and deliriants. Unlike other drugs such as stimulants  and opioids  which induce familiar states of consciousness, psychedelics tend to bend and twist the mind in ways that result in the experience being qualitatively different from those of ordinary consciousness. The psychedelic experience is often compared to non-ordinary forms of consciousness such as trance, meditation, yoga, and dreaming.
