In an effort to better understand the nature of addiction and how it should be treated we present some of the leading thinkers on the subject. On this page we ask prominent scholars, researchers, practitioners, politicians and writers for their definition of addiction, how it should be treated, and how they understand the role of the faith in the healing process. Each will include resources to support their assertions.
