“Narcotics that induce hallucinations are variously called hallucinogens (hallucination generators), psychotomimetics (psychosis mimickers), psychotaraxics (mind disturbers), and psychedelics (mind manifesters).
No one term fully satisfies scientists, but hallucinogens comes closest. Psychedelic is most widely used in the United States, but it combines two Greek roots incorrectly, is biologically unsound, and has acquired popular meanings beyond the drugs or their effects.”
