A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect.[1] Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue.

In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect.[2] A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being.[3] Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis.[4] Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders.[3]
