NCT01760473

Brief Summary

The study is designed to compare the abuse liabilities of intranasal buprenorphine and buprenorphine/naloxone in individuals who are physically dependent on sublingual buprenorphine. The investigators hypothesize that the abuse liability of buprenorphine/naloxone is lower than that of buprenorphine alone.
