You see he is going to try and fight it with a very original argument....here is a quote from his lawyer Ross Goodman
Goodman has taken an aggressive stance and asserts that Diaz has not tested positive for a banned substance. Goodman argues that Diaz did not test positive for Delta-9-THC, the active ingredient in marijuana, but rather for marijuana metabolites. Those metabolites are an inactive ingredient in marijuana and are not on the World Anti Doping Agency's banned list that Nevada uses, Goodman said.
That will be an interesteing Athletic commision hearing!
