At ONDCP, Dr. McLellan worked on a broad range of drug issues, including formulation and implementation of the President’s National Drug Control Strategy (including the much-heralded end of the War on Drugs) and promotion of drug treatment through the broader revamping of the national health care system. Dr. McLellan has more than 35 years of experience in addiction treatment research. In 1992 he co-founded and led (until his ONDCP appointment) the Treatment Research Institute to transform the way research is employed in the treatment of and policy making around substance use and abuse. Dr. McLellan’s contributions to the advancement of substance abuse research and the application of these findings to treatment systems and public policy have changed the landscape of addiction science and improved the lives of countless Americans and their families. In his career he has published over 400 articles and chapters on addiction research. From 2000-2009 he was editor-in-chief of the Journal of Substance Abuse Treatment, and he has also served on several other editorial boards of scientific journals.
