- psychoactive substance
- Also known as drug. The term psychoactive substance comes from the Greek noun psuchè (life breath, spirit, soul, mind) and the Latin adjective activus (active). It is used as a generic term for substances which, in a sufficiently high dose, have the potential to alter the user's state ofconscious-ness. A person intentionally employing psychoac-tive substances for the purpose of exploring the psyche may be called a * psychonaut.ReferencesRudgley, R. (1998).
