National Anti-Doping Organizations (NADOs) are agencies established by countries to promote fair play in sports by preventing the use of performance-enhancing drugs. They are responsible for implementing anti-doping policies, conducting drug testing, and educating athletes about the dangers of doping. NADOs work in alignment with international standards set by the World Anti-Doping Agency (WADA). Each NADO operates within its own country, ensuring that athletes comply with anti-doping regulations. They collaborate with sports federations, governments, and other stakeholders to create a clean sporting environment. By enforcing rules and providing resources, NADOs help maintain the integrity of sports at all levels.
