Compulsion vs Addiction

The former is an overwhelming desire (or sense of physical need) to do something, while an addiction is a physical or chemical dependence on a substance or behavior. | For instance, alcoholism, drug abuse, smoking, and gambling are perhaps the most common examples of addictions. | People with advanced addictions will continue their addictive behavior, even when they understand that doing so is harmful to themselves and others. | A compulsion is different from an addiction.
