Drug (French: Drogue-a dry herb): It is the single active chemical entity present in a medicine that is used for diagnosis, prevention, treatment/ cure of a disease. This disease oriented definition of drug does not include contraceptives or use of drugs for improvement of health. WHO(1966) has given a more comprehensive definition-"Drug is any substance or product that is used or is intended to be used to modify or explore physiological systems or pathological states for the benefit of the recipient."
The term 'drugs' is being also used to mean addictive/abused substances.
