Good move by Diaz to say that. Anyone watchin the conference yesterday could see the anger that created in GSP. It really knocked him off balance. Now he is pissed, and probably more likely to make a mistake. Mission accomplished Diaz.
As far as weed being performance enhancing. I wish I was one of the select few it was like PCP for. I have smoked weed before soccer training, and my cardio and performance is about 60%. Did it before a match once and was a shambles on the field. I think your kidding yourself raba if you think it improves your performance - especially in terms of your reflexes and reactions which are no doubt slowed down, and that it has more then a slight effect on the pain barrier.
Maybe its all the gatorade your sucking down due to the low blood sugar levels from smokin weed that is giving your extra kick!!
