All About Addictions

I found this very interesting interview/transcript from Dr. Drew, who most of us are familiar with. In the transcript, people ask Dr. Drew various questions about all kinds of addictions. Dr. Drew makes a very clear statement about addictions in the beginning stating that the term "addiction" is used very inaccurately. Dr. Drew defines an addiction as "a specific biological disorder of the reward systems of the brain that permanently alters the survival system and thus the motivational priorities." Basically, addictions are based predisposed by our genes. If someone does not have a certain "addiction gene" they cannot possess an addiction. He mentions that people are often seen as having an addiction, when they simply have bad habits, or a dependency. I previously saw "addictions" as something that one partakes in regularly. We obviously overuse the word "addiction" in everyday language which leads to misconceptions. The article is sort of long, but it covers all addictions from online gambling, sex addictions, and of course drugs and alcohol. Does this article change your view towards addiction? Or was your perception of addiction similar to this? What did you find interesting in the interview?
