This is from a thread on the brain and addiction, that is in the works.. but i think it is inherently relevant here.. this post hasn't had a final proof so if any one notices an edit please point it out as it will definitely be appreciated ( just quote it and proof it if you are good at this).. also it is part of a much longer thread and concept so loose ends will exist.
Whats Going On In The Brian With Addiction?
For what the flesh desires is opposed to the Spirit, and what
the Spirit desires is opposed to the flesh; for these are opposed
to each other, to prevent you from doing what you want.
—St. Paul, Galatians 5:171
If Passion drives, let Reason hold the Reins.
—Benjamin Franklin
The biggest delusion we face, when understanding addiction or human behavior, is that the conscious mind is really in charge. At best, the prefrontal cortex or conscious mind, is only responsible for a portion of our actions and shares responsibility and control, with other more elusive parts of the brain. In realty the conscious mind may just be a tool that is manipulated through emotion, to solve the problems the unconscious mind has attaining it goals. The unconscious mind is the limbic system or paleomammalian parts of the Brain, while the conscious has a center in the prefrontal cortex.
The exact way that the brain works is still greatly based on speculation and hypothesis. This exploration will present evidence for a theoretical model of how the brain works that best seems to explain addiction, There may be evidence presented that have portions have parts that contradict each other or the main theory of this thread. We will draw on current work from some brilliant minds currently working on deciphering this amazingly complex system. Evidence from different views may be linked for your consideration. However, we are going to promote the ideas that explains addiction the best.
Jonathan Haidt, author of
The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom, uses an analogy of an elephant and a rider to describe the relationship between the unconscious mind and the conscious. The unconscious or limbic system is the elephant and the conscious mind or the prefrontal cortex is the the driver. He is of the belief that the elephant or unconscious mind loves pleasure above all else and is described as animalistic. The conscious on the other hand is described as the divine or spiritual and rational portion of the mind. He states that the conscious mind can not control the unconscious; instead the prefrontal cortex tries to guide the elephant and is thus portrayed as the rider. His thoughts are by no means new and correlate with many of the most amazing minds in recorded history. I have linked the first chapter below that explores the idea of the "divided self." I have also created a link to a free E-copy of the entire book and as it truly is filled with mountains of wisdom you may consider reading it. Many of the principals in this book have made my recovery much easier and loads more peaceful.

Addiction does not distinguish between intelligence or level of education. The goal through out this exploration will be to make this theory accessible to everyone. Through our subjects multiple explanations of varying technical levels will be provided in an attempt to provide access to this information to everybody. So if you do not understand portions of the more technical explanations or links dont loose heart. The simplified explanations are designed to carry the basic principle.
Once you understand the basic principal I would suggest that you try and increase your knowledge and understanding of this subject by studying the more complex material and developing a strong working knowledge of whats going on. Knowledge is power and the more power we have to figure this out the less people will suffer. The disgusting way in which addicts are often treated and the stigmatism they face will only change when more people understand what addition is.
This thread will look at different parts of the brain and different chemicals that are found in the brain and will use these to explain what addiction is and how and why it happens. The limbic system is a portion of the brain that has been around much longer than the prefrontal cortex and is also called the paleomammalian brain. The prefrontal cortex is the portion of the brain that is responsible for problem solving and "implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behavior."

Also at the heart of addiction is the dopamine reward pathway or VTA and it resultant drives.
