WADA: there is no scientific evidence about effects of caffeine on performance

The Australian Olympic Committee (AOC) believes that caffeine should be included in prohibited medicines of the World Anti-Doping Agency. The president of the AOC John Coates confirms that caffeine promotes addiction to sleeping remedies and tranquillisers.
It is known that the Australian swimmers who took part at the 2004 and 2008 Olympic Games took sleeping tablets Stilnox. Thus, the president of the AOC notices that administration of caffeine resulted in administration of Stilnox.
Stilnox is ordinarily sold under the commercial name Zolpidem. It is a sleeping remedy which is taken in case of insomnia.
The president of AOC notices that athletes take caffeine for enhancement of performance. Consumption of this substance leads to insomnia. So, athletes should use sleeping tablets in order to treat insomnia.
 The AOC and Swimming Australia desire to prohibit usage of caffeine. It is their response to the disgrace related to Grant Hackett. A physician recommended taking Stilnox to this athlete at the time of the 2003 World Championships. As a result, the athlete became addicted to this sleeping remedy.
Grant Hackett is a well-known swimmer. He won numerous competitions, including the 2000 Sydney Olympics, the 2004 Athens Olympics and the 2008 Beijing Olympics.
Alan Thompson, the former coach of the Australian Olympic Team, has also affirmed that intake of Stilnox is widely spread among Australian swimmers.
Stilnox was never on the list of forbidden preparations. Anti-doping agencies didn’t conduct tests to discover usage of this medicine.
But when it comes to caffeine, previously it was banned by the WADA. But since it became widely spread and used in society, it was excluded from the list of prohibited substances.
John Fahey, the president of the WADA, claims that the WADA made the right decision and excluded caffeine from list of banned products. He confirmed that caffeine would not be included in the list of banned products again.
However numerous experts confirm that caffeine is a performance enhancer, John Fahey contests this statement. He confirms that caffeine doesn’t impact on performance. He concludes that no any scientific literature describes capacity of caffeine to increase performance.
