To study the response of objective and quasi-objective 'True' functional outcomes, analgesia and safety in chronic non-radicular back pain to buprenorphine buccal film (BBF) using a small 'n' phase IV design. To assess associations between traditional pain relevant subjective outcomes and objective or quasi-objective functional outcomes; In a small 'n' construct, to assess more powerful, 'new' statistical methods (e.g. hierarchical linear models, joint trajectory analysis) compared to traditional methods, in the context of increased power, more objective outcomes and cost savings. First a 2-week washout of any opioid medication (if necessary; if not necessary subject can proceed directly to); baseline week (Single Blind Placebo Lead In (SBPLI), using the placebo film resembling the 150mcg dose; then randomization to a \~ 2 week up titration either to effective Buprenorphine Buccal Film (BBF) dose 2 day average pain better than or equal to 3/10 NRS), highest tolerated dose BBF and/or maximum dose BBF of 900 mcg BID, or identical placebo material up to these parameters. This up titration is at the discretion and timing of the blinded and experienced PI. Subject will be allowed two doses of hydrocodone/acetaminophen 5/325 daily during the washout period. A single experienced practitioner will manage the titration as to safety, detail and timing; and determine when the subject enters the 8 week stable dose trial; this practitioner will remain blinded throughout unless there is an urgent, safety reason for unblinding
