For other meanings, see Drug (disambiguation)

A drug is any substance that can be used to treat an illness, relieve a symptom, or modify a chemical process or processes in the body. The term is necessarily a vague one, being defined by intent: for example, foods consumed for normal metabolism are not generally considered "drugs", but the same foods consumed for a more specific purpose (such as the use of alcohol as a depressant or caffeine as a stimulant) may be. Depending on the definition used, the same substance may even be considered both a food and a drug at the same time. In a medical context, the term "medication" is frequently used to refer to drugs, presumably to avoid conflation with recreational drugs.

In the United States, drugs are distributed by pharmacies, which in turn purchase drugs from pharmaceutical companies. Most drugs are extremely expensive when first distributed. When the patent for the drug runs out, a generic is usually created by a competing company and released, causing the price to drop markedly.
