UFC fighter Nate Diaz has accepted a warning from the US Anti-Doping Agency (Usada) for his use of prohibited substance Cannabidiol.
The American fighter admitted using the legal high after his loss to Ireland’s Conor McGregor in August.
Cannabidiol, a compound found in cannabis, is known anecdotally for its medicinal benefits for people with severe epilepsy.
The 31-year-old lost the UFC 202 fight by a majority decision.
Usada concluded that Diaz mistakenly believed that the in-competition period ended after he provided a post-bout sample.
