PY - 2019 T2 - Goldfrank's Toxicologic Emergencies, 11e AB - A “hallucination” is defined as a false perception that has no basis in the external environment. The term is derived from the Latin “to wander in mind.” Hallucinations differ from illusions, which are distorted perceptions of objects based in reality. Although the term psychedelic has been used for years to refer to the recreational and nonmedical effects of hallucinogens, other terms, such as entheogen and entactogen, frequently appear in discussions. Entheogens are “substances that generate the god or spirit within,” and entactogens create an awareness of “the touch within.”50 These terms all refer to the same xenobiotics, used with differing intent or in varying settings.
