The Stockton Samurai is scheduled for an August 5 clash with ‘The Problem Child’ Jake Paul at the American Airlines Center in Dallas. Diaz will be making his professional boxing debut but was dealt a blow ahead of the bout when it was revealed that he would be subject to testing for performance-enhancing and recreational drugs, including marijuana. Anyone who is familiar with Nate Diaz or his brother, Nick, Diaz, knows that the two are quite fond of recreational marijuana use, often flaunting it at events, press conferences, and even while submitting a test to the United States Anti-Doping Agency.
