What is cannabidiol?

Along with tetrahydrocannabinol (THC), cannabidiol (CBD) is one of many cannabinoids contained in the cannabis plant. Recently, various claims have been made regarding the medical or therapeutic benefits of CBD.

Is cannabidiol legal?

While there has been a trend towards increasing legalisation of cannabis and cannabinoids, it is recommended that local laws are consulted to establish the most up-to-date status of cannabidiol and/or other cannabinoids.

Is cannabidiol prohibited in sport?

No. However, all other cannabinoids are prohibited (In-Competition only). The full WADA Prohibited List is available on the Tennis Anti-Doping Programme (TADP) app, which all players are recommended to download (search ‘Tennis Anti-Doping Programme’ on your app store).

Are there any risks associated with the use of cannabidiol?

Yes. Many products which claim to be pure CBD extract or oil from the cannabis plant may be contaminated by THC or other (prohibited) cannabinoids. One reason for this is that it is difficult to obtain a pure CBD extract or oil from the cannabis plant. It is not possible to identify the concentration of each ingredient. Users, therefore, expose themselves to the risk of an Anti-Doping Rule Violation by using CBD, particularly if that use is during or close to competitions.


Due to the risk of contamination described above, the TADP recommends that players do not use CBD products, as doing so exposes the user to an Anti-Doping Rule Violation.
