There is no way Nate has not been smoking weed out of a normal camp. Even if Conor loses, the decision will get overturned in his favor. Nate will most likely test positive for a banned substance after the fight. Doesnt weed stay in your system for a month? So nate would have needed a month to clear it out and he isnt getting that much time. This is all speculation obviously, but its a good assumption imo.
