Nick Diaz argues with USADA agent in Snapchat video before drug test

Nick Diaz is not on the best of terms with the United States Anti-Doping Agency (USADA).

Bloody Elbow's Michael Hutchinson tweeted a video of Diaz arguing with a USADA agent over an impromptu drug test. Diaz, who's traveled to Las Vegas for his brother Nate's rematch with Conor McGregor at UFC 202, is coming off an 18-month suspension for marijuana, and must undergo random testing in order to return to active competition.

In the video, a worked-up Diaz pleads with the agent to allow him five or six hours to sleep before meeting for the test, claiming he'd been out all night:

In a second video, a tucked-in Diaz claims to have given the agent his Las Vegas hotel room number in an attempted compromise:

A third Snapchat video was later released that seems to depict Diaz being tested by a USADA agent.
