im really pissed about this as well, i wanted to see this fight and i am a huge fan of nick's.
Haven't clicked the link (read the article elsewhere) but I wanted to add that according to Cesar Gracie camp, Nick had been told that his medical marijuana prescription would be honored by the CSAC and marijuana would not be considered in the test. Then they turned around right before the test and told him that marijuana would mean a hot test. I'm guessing Nick knows he would piss hot so he just decided not to show.
IF you think about it, it was the best choice at this point in time, since not showing simply means he will miss this fight- a hot test would likely mean a lengthy suspension.
IMHO he shoulda just bought a system cleaner. I fooled quest labs (who almost 100% would be processing the sample) a dozen times or so with them, only got caught once and i have to admit i didnt follow the instructions on the bottle.
His helmet was stifling, it narrowed his vision. And he must see far. His shield was heavy. It threw him off balance. And his target is far away.
