Moyers on Addiction: The Hijacked Brain

Aided by powerful new diagnostic tools, scientists are making dramatic discoveries about how addiction affects the brain. In this program, Moyers goes into the laboratory to follow researchers engaged in charting an "image of desire in the brain". We actually see images of a cocaine user's brain as the drug takes effect, and a doctor explains how these scans reveal addiction as a chronic relapsing brain disease. Moyers observes a genetic researcher as he monitors a variety of factors that may determine who is likely to develop alcoholism.
