The implications of the research continuing to be conducted by the National Institutes of Health (NIH) and other medical & research organizations is amazingly huge... We are gaining a better and better understanding of how addiction affects certain areas of the brain. Even though this study was based on cocaine addiction, it confirmed what we already largely knew: deficits in the prefrontal cortex are involved in drug addiction. This information gives us a better understanding of these deficits and shows even more promise for developing effective therapies that target that part of the brain... This could translate into a better understanding of (and, as such, better treatment modalities to treat) opioid addiction as well. The field of addiction treatment and medicine is alive and well as evidenced by the massive strides in research and understanding that are developing each and every day.
