In 2001, USADA was recognized by the U.S. Congress as "the official anti-doping agency for Olympic, Pan American and Paralympic sport in the United States." While USADA is not a government entity, it 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 largely relies on USADA to carry out this commitment.
