Claire Parry, LLB, Associate at Kingsley Napley, in a Mar. 12, 2019 article, "Medical cannabis in sport – what athletes need to know," available at, stated:

“Cannabis itself contains over 100 known types of cannabinoids, one of them being cannabidiol, otherwise known as CBD. CBD is the cannabinoid thought to possess medicinal benefits, including pain relief; however there are doubts about whether CBD is effective in itself without the presence of other cannabinoids, such as THC. THC, or tetrahydrocannabinol, is arguably the most well-known of the cannabinoids as it possesses the psychoactive properties relied upon by users to get ‘high’.

I am an athlete. Which type of cannabis is banned? And when?
The World Anti-Doping Agency (WADA) Prohibited List sets out the Prohibited Substances which are prohibited at all times, and those that are only prohibited ‘in-competition’ (i.e. 12 hours before competition through to the end of the competition and sample collection).

Section 8 states that both natural and synthetic cannabinoids, including THC, are prohibited in-competition only. The only exception is CBD, which athletes are permitted to use at any time.

It is important to note that unlike with all other banned cannabinoids, the level of THC must reach a certain threshold in order to return a positive test (a positive test may also be referred to formally as an Adverse Analytical Finding or ‘AAF’). The threshold for THC to return an AAF is 150 nanograms per millilitre of urine.”
