I remember something about the way it's worded in the CBA that the reason they test for Marijuana being that it is against the law and that's why they are allowed to punish them, I could be wrong. What happens when a Denver or Seattle player pisses positive and fights the suspension based on the wording of the CBA?
Also fuck this Marijuana testing of athletes, the shit isn't a fucking PED and actually would help a lot of these violent assholes calm the fuck down, Aldon Smith might just be a pot head instead of drunken fucking moron risking the lives of himself and the drivers near him. Hell I bet it would cut down on the DUI's the league is riddled with.
