Suboxone contains buprenorphine and naloxone, at a 4:1 ratio. The naloxone (which is an opioid antagonist) is included to discourage abuse, though due to buprenorphine's higher affinity to receptor sites, it is basically inactive.
Other than that, the only difference is the taste, color and shape, you should still get the same buzz or reliefe from withdrawals. I'm going to close this, for more information, please read through the Suboxone/Buprenorphine Mega Thread and FAQ
