Nate Diaz Gets Verbal Warning For Using Vape Pen Following UFC 202 Loss

Nate Diaz will not face formal disciplinary action for using a vape pen after his loss to Conor McGregor at UFC 202. A statement from USADA said that Diaz “has admitted using a prohibited substance during the in-competition period and has accepted a public warning for his policy violation.”

Diaz admitted online that he was vaping from a pen that containted CBD, which is one of 113 active cannabinoids in cannabis per MMAjunkie.

USADA said that they decided not to punish Diaz because he “mistakenly believed that the in-competition period ended after he provided a post-bout sample to USADA. In addition, the in-competition urine and blood samples provided by Diaz before his admitted use were analyzed and reported as negative for all prohibited substances, including Cannabinoids. Based on these circumstances, USADA determined that a public warning was an appropriate response to Diaz’s use of a specified substance during the in-competition period.”
