Psychoactive drug or substance
August 17, 2023
A substance that, when ingested, affects mental processes, e.g. cognition or affect. This term and its equivalent, psychotropic drug, are the most neutral and descriptive terms for the whole class of substances, licit and illicit, of interest to drug policy. “Psychoactive” does not necessarily imply dependence-producing, and in common parlance, the term is often left unstated, as in “drug use” or “substance abuse”.(See also drug.)
