Addiction is a very complex and sophisticated disease. Kristina Wandzilak, a professional interventionist featured in the TLC show "Addicted," puts it like this, "Addiction is a combination of genetic, biochemical, social, environmental and psychological events in a person's life that collide to create and manifest an addiction. And it's especially tricky to identify, because it rarely looks the same in any two people."
