The World Anti-Doping Agency (WADA) publishes a List of Prohibited Substances and Methods on an annual basis, which is mandatory for every signatory of the World Anti-Doping code. It is one of the five mandatory international standards of the signatories and includes substances and methods prohibited and banned. In section S8 of the Prohibited List effective as of January 2018 it is shown that Cannabidiol (CBD) is the only Cannabinoid that is exempted from the list and therefore will not be prohibited.
