Drug: The Oxford Concise Dictionary defines drug as "original simple medicinal substance, organic or inorganic, used alone or as an ingredient." The word as defined in this Act has, however, a much wider connotation. As per definition of the word drug as defined in the Act any substance or mixture of substances used in the treatment, mitigation, prevention, or diagnosis of disease in human beings or animals, or the restoration, correction, or modification of organic functions in human beings or animals, not being a substance exclusively used in accordance with the Ayurvedic, Unani. Homeopathic or Biochemic system of treatment, abortive and contraceptive substances and devices, surgical ligatures, sutures, bandages absorbent cotton, disinfectants, adhesive plasters, gelatine capsules, antiseptic solutions, pesticides, any substance mentioned as monograph or as a preparation in the Pakistan Pharmacopoeia or International or British Pharmacopoeia or United States Pharmacopoeia or formulary, whether lone or in combination with any substance exclusively used in the Unani, Ayurvedic, Homeopathic or Biochemic system of treatment, and such substance as the Federal Government may declare to be a drug for purposes of this Act shall be deemed to be a drug. It will thus appear that it is not only the drugs that are used in the cure, prevention, mitigation etc., of a disease that fall within the definition but even such articles as are used in the diagnosis, treatment, prevention or mitigation of diseases are covered within the term.
