Sorry, we can't tell you how to use your medication to get high. This board is for HR (harm reduction) purposes.
We can help you do what you're already going to do as safely as possible, however.
That said, Buprenorphine isn't an opiate classically used to get a high from; it's an addiction maintenance drug (and in some cases pain management, but that's relatively new). The films, IMO, are wonderful for tapering an addiction down. They're extremely easy to cut into very tiny doses to allow a proper taper without any rough jump-offs.
