Usage of caffeine by athletes

The Australian Olympic Committee (AOC) confirms that caffeine should be included in banned medicines of the World Anti-Doping Agency. The president of the AOC John Coates affirms that caffeine induces addiction to sleeping tablets and tranquilizers.
It is known that the Australian swimmers that competed at the 2004 and 2008 Olympic Games used sleeping tablets Stilnox. Thus, Coates believes that application of caffeine led to usage of Stilnox.
Stilnox is ordinarily sold under the commercial name Zolpidem. It is a sleeping remedy that is used in case of insomnia.
Coates confirms that athletes use caffeine in order to increase performance. Consumption of this substance leads to insomnia. So, sportspersons should apply sleeping tablets in order to treat insomnia.
 The AOC and Swimming Australia desire to ban usage of caffeine. It is their response to the disgraceful case connected with Grant Hackett. A physician recommended using Stilnox to this swimmer at the time of the 2003 World Championships. As a result, the athlete became addicted to this sleeping remedy.
Grant Hackett is a prominent swimmer. He won certain 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 products. Anti-doping agencies didn’t conduct tests to disclose administration of this product.
But as for caffeine, earlier it was prohibited by the WADA. But since it became widely spread and used in society, it was excluded from the list of prohibited products.
John Fahey, the president of the WADA, notes that the WADA made the right decision and excluded caffeine from list of forbidden drugs. He confirmed that caffeine would not be included in the list of prohibited substances again.
However many experts claim that caffeine is a performance enhancer, John Fahey contests this argument. He affirms that caffeine doesn’t impact on performance. He concludes that no any scientific literature describes ability of caffeine to enhance performance.
