Argument: Addiction researchers can rely on animals having no prior drug use
Edythe London, UCLA researcher. "Why I use laboratory animals". Los Angeles Times. November 1, 2007 - "My work on the neurobiology of addiction has spanned three decades of my life -- most of this time as a senior scientist at the National Institutes of Health. To me, nothing could be more important than solving the mysteries of addiction and learning how we can restore a person's control over his or her own life. Addiction robs young people of their futures, destroys families and places a tremendous burden on society.
Animal studies allow us to test potential treatments without confounding factors, such as prior drug use and other experiences that complicate human studies."
