UVA CLEAR: Center for Leading Edge Addiction Research

The University of Virginia’s Center for Leading Edge Addiction Research or CLEAR clinic is the site of ongoing research studies on substance abuse for the Department of Psychiatry and Neurobehavioral Sciences’ Division of Neurobiological Studies.

Through our research, we hope to bring new knowledge to better understand the biological underpinning of addiction. Our approach combines medications, which target different brain pathways known to be involved in the rewarding effects of drugs, with behavior-changing techniques in an effort to reduce craving associated with substance abuse.
