 WADA(World Anti-Doping Association) History

1999年11月10日，世界反興奮劑機構在洛桑成立。這標志著國際反興奮劑協調行動的開始。它的主要任務是負責審定和調整違禁藥物的名單，確定藥檢實驗室，以及從事反興奮劑的研究、教育和預防工作。

The World Conference on Doping in Sport held in Lausanne on 2-4 February 1999 produced the Lausanne Declaration on Doping in Sport. This document provided for the creation of an independent international anti-doping agency to be fully operational for the Games of the XXVII Olympiad in Sydney in 2000.

Pursuant to the terms of the Lausanne Declaration, the World Anti-Doping Agency was established on 10 November 1999 in Lausanne to promote and coordinate the fight against doping in sport internationally. WADA was set up as a foundation under the initiative of the IOC with the support and participation of intergovernmental organizations, governments, public authorities, and other public and private bodies fighting against doping in sport. The agency consists of equal representatives from the Olympic Movement and public authorities.
