Ketamine is a dissociative anesthetic that, at sub-anesthetic doses, induces altered states of consciousness — including, in many cases, experiences that closely resemble near-death experiences. Its dissociative profile has made it a focus of psychometric and clinical research on subjective effects, posttraumatic symptoms and the comparative phenomenology of altered states. ICEERS gathers here content on ketamine, including research on ketamine-induced near-death experiences and its place within the broader landscape of psychoactive substances.
