The primary objective of this study is to compare overall patient preference for either Suboxone® sublingual film 8/2 or Zubsolv® sublingual tablets 5. 7/1. 4. Suboxone sublingual film 8/2 contains 8mg buprenorphine and 2mg naloxone. Zubsolv sublingual tablets contain 5. 7 mg buprenorphine and 1. 4 mg naloxone. Both interventions act as a substitute for opiate drugs like heroin, morphine or oxycodone and help withdrawal from opiate drugs over a period of time.
