The International Convention against Doping in Sport is a multilateral UNESCO treaty by which states agree to adopt national measures to prevent and eliminate drug doping in sport. States that agree to the Convention align their domestic rules with the World Anti-Doping Code, which is promulgated by the World Anti-Doping Agency. This includes facilitating doping controls and supporting national testing programmes; encouraging the establishment of 'best practice' in the labelling, marketing, and distribution of products that might contain prohibited substances; withholding financial support from those who engage in or support doping; taking measures against manufacturing and trafficking; encouraging the establishment of codes of conduct for professions relating to sport and anti-doping; and funding education and research on drugs in sport. The Convention was adopted at the General Conference of UNESCO in Paris on 19 October 2005. It entered into force on 1 February 2007 after it had been ratified by 30 state parties. As of February 2018, the Convention has been ratified by 187 states, which includes 185 UN member states plus the Cook Islands and State of Palestine. The following eight UN members are states that are not parties to the Convention:
