In competitive sports, doping refers to the use of banned athletic performance-enhancing drugs by athletic competitors, where the term doping is widely used by organizations that regulate sporting competitions. The use of banned drugs to enhance performance is considered unethical, and therefore prohibited, by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbates the ethical violation with overt deception and cheating.
Historically speaking, the origins of doping in sports go back to the very creation of sport itself. From ancient usage of substances in chariot racing to more recent controversies in baseball and cycling, popular views among athletes have varied widely from country to country over the years. The general trend among authorities and sporting organizations over the past several decades has been to strictly regulate the use of drugs in sport. The reasons for the ban are mainly the health risks of performance-enhancing drugs, the equality of opportunity for athletes, and the exemplary effect of drug-free sport for the public. Anti-doping authorities state that using performance-enhancing drugs goes against the "spirit of sport".
There are many suggestions as to the origin of the term doping. One is that it is derived from dop, an alcoholic drink used as a stimulant in ceremonial dances in 18th century Southern Africa. Another suggestion is that the word comes from the Dutch word doop (a thick dipping sauce) that entered American slang to describe how robbers stupefied victims by mixing tobacco with the seeds of Datura stramonium (jimsonweed) which contains a number of tropane alkaloids, causing sedation, hallucinations and confusion. By 1889, "dope" was used in connection with the preparation of a thick viscous preparation of opium for smoking, and during the 1890s this extended to any stupefying narcotic drug. In 1900, dope was also defined as "a preparation of drugs designed to influence" the performance of a racehorse.
The use of drugs in sports goes back centuries, about all the way back to the very invention of the concept of sports. In ancient times, when the fittest of a nation were selected as athletes or combatants, they were fed diets and given treatments considered beneficial. For instance, Scandinavian mythology says Berserkers could drink a mixture called "butotens", to greatly increase their physical power at the risk of insanity. One theory is that the mixture was prepared from the Amanita muscaria mushroom, though this has been disputed. The German missionary and doctor Albert Schweitzer wrote of Gabon in the early 19th century: "The people of the country can, having eaten certain leaves or roots, toil vigorously all day without feeling hungry, thirsty or tired and all the time showing a happiness and gaiety."
