New definition of addiction: Addiction is a chronic brain disease, not just bad behavior or bad choices

New definition of addiction: Addiction is a chronic brain disease, not just bad behavior or bad choices: "When people see compulsive and damaging behaviors in friends or family members -- or public figures such as celebrities or politicians -- they often focus only on the substance use or behaviors as the problem. However, these outward behaviors are actually manifestations of an underlying disease that involves various areas of the brain, according to a new definition."
