The Nevada State Athletic Commission issued no new therapeutic-use exemptions for testosterone replacement therapy at UFC 162 but did give UFC middleweight Chris Leben permission to use the prescription opioid medication Suboxone. Leben (22-10 MMA, 12-9 UFC), who lost a split decision to Andrew Craig (9-1 MMA, 3-1 UFC) at this past Saturday’s event, is the first fighter to receive an exemption for the drug, which typically is used as a replacement therapy for people with narcotic dependency. NSAC Executive Director Keith Kizer confirmed the news today with MMAjunkie.com (www.mmajunkie.com). Leben was unreachable for comment. The veteran fighter’s exemption offers proof of his efforts to get clean following a well-documented struggle with drugs. In November 2011, he tested positive for oxycodone and oxymorphone following a loss to Mark Munoz at UFC 138 and was suspended by the UFC for one year.
