June 2008 Reports on a study involving researchers who successfully desensitized mice to cocaine by genetically altering their dopamine transporters.
June 2008 Describes a booklet that explains what scientists know about how drug addiction changes the brain and affects behavior and clears up misconceptions about drug addiction.
March 2008 Reports on research showing that the neurons that deliver dopamine to two regions of the brain's mesolimbic reward system respond differently to opioids, an important finding for drug treatment research.
March 2008 Reports on results from a study showing that men and women with alcohol use disorders are more likely to report nonmedical use of prescription drugs than people who don't drink at all.
March 2008 Summarizes research on the effects of long-term regular cocaine abuse on the cardiovascular system in African Americans.
