Kenneth Grasing, M.D. is Associate Professor of Medicine at the University of Kansas School of Medicine and Director of the Substance Abuse Research Laboratory at the Kansas City VA Medical Center. Dr. Grasing’s research interests include developing new therapies to decrease drug reinforcement and prevent relapse in substance abuse disorders. His laboratory has evaluated various medications as potential treatments using both preclinical and clinical methods. In particular, medications that augment actions of acetylcholine can cause long-lasting reductions in cocaine-reinforced behavior in animal studies. Genetic models of psychiatric disorders are another area of interest, and the Substance Abuse Research Laboratory has produced two rat strains which differ in their self-administration of cocaine.
