| 1. | When opioids attach to the mu receptors, dopamine is released, causing pleasurable feelings to be produced.1,2 |

| 2. | As opioids leave the receptors, pleasurable feelings fade and withdrawal symptoms (and possibly cravings) begin.1 |

| 3. | Opioids continue leaving the mu receptors until the person is in a mild-to-moderate state of withdrawal. At this point, SUBOXONE therapy can begin. |

| 4. | The primary active ingredient in SUBOXONE—buprenorphine—attaches to the empty opioid receptors, suppressing withdrawal symptoms and reducing cravings.1 As a partial opioid agonist, SUBOXONE works by controlling withdrawal symptoms and cravings and produces a limited euphoria or "high."1 |

| 5. | Buprenorphine attaches firmly to the receptors. At adequate maintenance doses, buprenorphine fills most receptors and blocks other opioids from attaching. Buprenorphine has a long duration of action, so its effects do not wear off quickly. |
