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 U.S. Congress recognized USADA as "the official anti-doping agency for Olympic, Pan American and Paralympic sport in the United States."

Since its inception in 2000, USADA has worked to preserve the integrity of competition, inspire true sport and protect the rights of athletes in the Olympic & Paralympic movement in the United States.

With the vision to be the guardian of the values and life lessons learned through true sport, our organization's anti-doping programs are comprehensive,  including in-competition and out-of-competition testing, results management and adjudication processes, drug reference resources and therapeutic use exemption process, scientific research initiatives, and athlete and outreach education. USADA continues to work to improve its system and anti-doping endeavors to further protect clean athletes and the health of future athletes.

As a non-profit, non-governmental agency, USADA's programs:

  • Provide deterrence and preservation of sport for athletes, coaches, students, teachers, parents, scientists and more through education and resources;
  • Include numerous protections for athletes to ensure that only athletes who are guilty of a doping violation are sanctioned;
  • Strive to systematically identify and sanction those individuals who are engaged in the effort to gain an advantage over athletes who are competing clean; and
  • Fund pioneering research for the detection of doping substances and techniques, and the pursuit of scientific excellence in doping control.
