Hey Schizo, respectfully disagree with a little something here. You don't really take Buprenorphine products orally, as you end up sacrificing a pretty large percentage of your possible bioavailability. This is why it is commonly dispensed as a sublingual-intended product.
Sublingual: ~30% bioavailability
Intranasal: ~50% bioavailability
Buccal: ~65% bioavailability
You can insufflate these pills and many people do. The one thing that worries me is that when insufflated, you do have the chance of the Naloxone and Buprenorphine producing powerful precipitated withdrawal. If you are Opioid dependent, just make sure you pay attention to your body and how you feel as best you can. If you're going to use Buprenorphine, I would really make sure that you're quite sick prior to using the Buprenorphine.
