A drug, broadly speaking, is any chemical substance that, when absorbed into the body of a living organism, alters normal bodily function.There is no single, precise definition, as there are different meanings in drug control law, government regulations, medicine, and colloquial usage.It defines a drug as "a chemical substance used in the treatment, cure, prevention, or diagnosis of disease or used to otherwise enhance physical or mental well-being."Drugs may be prescribed for a limited duration, or on a regular basis for chronic disorders.Some drugs can cause addiction and habituation.Many natural substances such as beers, wines, and some mushrooms, blur the line between food and drugs, as when ingested they affect the functioning of both mind and body.
