Well the time has finally come. The NSAC has officially raised the testing threshold of marijuana metabolites from 50 ng/mL to 150 ng/mL. Nick and Nate Diaz, Pat Healy, Matt Riddle, and all the other fighters who enjoy marijuana rejoice! Hopefully now we will not have any ridiculous failed tests and wins turned into No Contests. This is a long time coming. Simply put, marijuana is not a performance enhancing drug. Could this mean a return for Nick Diaz?
