When I was in rehab most of the people there were being treated with buprenorphine hydrochloride (we called it Suboxone). I got "high" off 4mg of it and so did a female patient as well. Our eyes were glazed over and everyone else could tell. The others said that it didn't make them feel anything except not dope sick. It wasn't intense just a nice feeling of well being. So to answer your question maybe 1 in 10 got high off a 4mg dose. I would assume more would have gotten high at larger doses. I have been told that with maintenance therapy the high goes away.
