Suboxone is basically a replacement drug which was synthesized to help opioid addicts. However, as its use progressed, it became evident that it can be addictive itself. Even medically supervised use of Suboxone can cause addiction. This is why it is only prescribed for a short term treatment. Suboxone addiction can be difficult to detect since most of the patient think that they are simply taking their medicine. But when the use is prolonged, certain signs and symptoms become obvious that may help to detect an addiction.
