The United States Anti-Doping Agency is a non-profit, non-governmental 501(c)(3) organization and the national anti-doping organization (NADO) for the United States. To protect clean competition and the integrity of sport and prevent doping in the United States with a performance-enhancing substance, the USADA provides education, leads scientific initiatives, conducts testing, and oversees the results management process. Headquartered in Colorado Springs, Colorado, USADA is a signatory to the World Anti-Doping Code, which harmonizes anti-doping practices around the world, and is widely considered the basis for the strongest and strictest anti-doping programs to prevent doping in sport.
In competitive sports, doping is the use of banned athletic performance-enhancing drugs (PEDs) by athletes, as a way of cheating. As stated in the World Anti-Doping Code by WADA, doping is defined as the occurrence of one or more of the anti-doping rule violations outlined in Article 2.1 through Article 2.11 of the Code. The term doping is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical and is prohibited by most international sports organizations, including the International Olympic Committee. Furthermore, athletes taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating.

The 4×100 metres relay at the World Championships in Athletics has been contested by both men and women since the inaugural edition in 1983. It is the second most prestigious title in the discipline after the 4×100 metres relay at the Olympics. The competition format typically has one qualifying round leading to a final between eight teams. As of 2015, nations can qualify for the competition through a top eight finish at the previous IAAF World Relays event, with the remaining teams coming through the more traditional route of ranking highly on time in the seasonal lists. This system was modified due to the postponement of 2023 World Athletics Relays to 2024: therefore, the eight teams directly qualified are those of the 2022 World Championships, in Eugene, completed by eight more 2022-2023 top lists' teams.
