The World Anti-Doping Agency now allows cannabidiol (CBD) to be taken in elite sport, but has retained all other cannabinoids on its banned list. This, together with liberalisation of cannabis laws, has led to an increasing interest in its use in sport. This includes commercial sponsorship of sporting events and highlights the need for accurate information to be readily available to athletes and their advisers. This narrative review confirms that CBD and tetrahydrocannabinol (THC) do not enhance performance. CBD possesses anti-inflammatory and analgesic properties that have not been adequately evaluated in the area of sport. Some formulations of CBD contain THC or other cannabinoids that may result in a positive drug test.
