The World Anti-Doping Agency (WADA) was established in 1999 as an international independent agency composed and funded equally by the sport movement and governments of the world. Its key activities include scientific research, education, development of anti-doping capacities, and monitoring of the World Anti Doping Code (Code) – the document harmonizing anti-doping policies in all sports and all countries.

The U.S. Anti-Doping Agency (USADA) is the national anti-doping organization (NADO) in the United States for Olympic, Paralympic, Pan American, and Parapan American sport. The organization is charged with managing the anti-doping program, including in-competition and out-of competition testing, results management processes, drug reference resources, and athlete education for all United States Olympic Committee (USOC) recognized sport national governing bodies, their athletes, and events. Additionally, USADA contributes to the advancement of clean sport through scientific research and education & outreach initiatives focused on awareness and prevention.

Drug Testing 101

Given the fact that drug-testing is largely reserved for elites and those winning races, the majority of people toeing the line at a race aren’t familiar with the process. And that unfamiliarity can make it seem like a scary proposition—out-of-competition testing, in-competiton testing, WADA, USADA, there’s a lot to process. The onus is on athletes to know the rules and refer to the list of banned substances when getting prescriptions. As for the testing process itself, learn from USA Track & Field here.
