United States Anti-Doping Agency

The United States Anti-Doping Agency (USADA) is a non-profit, non-governmental organization and the national anti-doping organization (NADO) for the United States. The organization has control of the anti-doping programs for U.S. Olympic, Paralympic, Pan-American and ParaPan American sport. Its work includes in-competition and out-of-competition testing, the results management and adjudication process, the provision of drug reference resources, the therapeutic-use exemption process, various scientific research initiatives, and athlete and outreach education. USADA is headquartered in Colorado Springs, Colorado.

USADA is a signatory to, and responsible for implementation in the United States of, the World Anti-Doping Code, widely considered the basis for the strongest and strictest anti-doping programs in sports. In 2001, the agency was recognized by the U.S. Congress as "the official anti-doping agency for Olympic, Pan American and Paralympic sport in the United States." USADA is not a government entity, however the agency is partly funded by the Office of National Drug Control Policy (ONDCP), with its remaining budget generated from contracts for anti-doping services with sport organizations, most notably the United States Olympic Committee(USOC). The United States has also ratified the UNESCO International Convention against Doping in Sport, the first global international treaty against doping in sport, and relies in a large part on USADA to carry out this commitment
