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.
