I tested positive for buprenorphine on a 10 panel screen. I have never taken Suboxone, nor even know anyone socially that has a suboxone contract. I do have chronic pain from a back injury 7 years ago. I take Tramadol  and a muscle relaxer for the daily pain. The mornings I have had to take an increased amount 100-150mg, I have tested positive for buprenorphine the mornings I have had to take the Tramadol.
