What Is This pill - With '8 and a arrow Imprint?

It is 8 mg. subutux, which is buprenorphine, used to treat opiate addiction. It is similar to suboxone, but without the ingredient that stops a person from "shooting" it. Most doctors would not prescribe it without total assurance that the patient would not inject it. It is an opiate blocker. However, it is an opiate, so it does relieve pain. When on buprenorphine, other opiates, such as percocet, percodan, oxycontin, etc. would be useless, as it blocks them from the receptors. It is also used to treat opiate overdose. (I am not a medical professional. I am a patient on subutex, and this info is correct to the best of my knowledge.)
