Overview and purposes of the CodeThe World Anti-Doping Code (the Code) harmonises anti-doping standards, rules and requirements globally. It is supported by eight International Standards which guide anti-doping organisations in various areas to ensure uniformity (eg in testing, investigations and results management).The Code is implemented through its Signatories, which include International Federations, National Olympic Committees, National Paralympic Committees, National Anti-Doping Organisations and Major Event Organisations. Typically, organisations adopt anti-doping rules which must conform with the Code and International Standards, with WADA monitoring compliance.Separately, more than 190 countries have ratified the UNESCO International Convention against Doping in Sport, a multilateral treaty which mandates governments to align their national legislation with the Code. For more information on this topic, WADA has published a webinar and presentation entitled ‘Anti-Doping Legislation: Keys to Success’ which can be accessed here and here.The Code, originally adopted in 2003, was revised in 2009 and 2015, before arriving at the 2021 edition. Revisions are made further to public stakeholder consultations, taking into account feedback provided by users. WADA helpfully provides
