A drug is any chemical substance, other than a food or device, that affects the function of living things. Technically, vitamin E, oxygen, and cocaine are all examples of drugs. Various drugs can be used to treat illness, or they can be used recreationally to alter behavior and perception.

The definition is somewhat fuzzy, because many substances which are not typically considered drugs are indeed active substances (ex. caffiene, nicotine, and even chocolate). Additionally, there are thousands of substances in foods and "nutritional supplements" which affect the function of living things. Many illegal and recreational drugs (such as cocaine, opium, and ephedra) could potentially be considered "foods" because they do have caloric content. That being said, the popular definition of a drug is any substance which causes an altered state of mind, caffiene and alcohol excluded. This may or may not include medications, which are strictly used to cure illness and by definition not used for recreation.
