I know I already said this but I would recommend to read The Brain That Changes Itself by psychiatrist Norman Doidge which discusses many aspects of neuroplasticity (which plays a great role in addiction).

Edit, nevermind, I missed later posts with links.

For instance
A study conducted at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory demonstrated that drug addicted individuals who have a certain genetic makeup have lower gray matter density — and therefore fewer neurons — in areas of the brain that are essential for decision-making, self-control, and learning and memory.

Another interesting report.

How about then neuroplasticity? That's an interesting component of intelligence and it has of course a neural chemistry component as well: learning favors certain paths, these path are reinforced by the act of learning, the learning changes neural paths and the change is reflected in learning. Now, does addiction have any effect on neural plasticity? Or something else you're interested in.

Addictions(especially behavioral ) plays right into neuroplasticity. ΔFosB is a main actor here

the TEDtalk by Psychologist Philip Zimbardo asks, "Why are boys struggling?" He shares some stats (lower graduation rates, greater worries about intimacy and relationships) and suggests a few reasons -- and he asks for your help! Watch his talk and Gary wilson's too ,the admin said I can't post so go look for it on youtube.

here the paper I got it from http://www.ncbi.nlm.nih.gov/pubmed/21499141
Ok that about "reducing dopamine receptors" (probably on the post-synaptic neuron) and is a consequence (I believe documented) of excessive dopamine in the synapses: the body adjust to excessive levels by decreasing the number of receptors. I believe that's the case anyway. I did not read the paper.

It's a study about the irregularities in the dopaminergic brain system associated with addiction.

if you can't read all the study just read the abstract.

Ok look, if "intelligene is not really understood" as you say, then how can we have a scientific discussion about it? But no wait, that depends on what you mean by understood. I bet there are a bunch of things we DO know about intelligence. Maybe if you focus on those and then try to see how addiction affects those things. And I think I'm right: whatever those things are, they will have a neurochemical component.
Yes of course there is a neurochemical component to intelligence but you can't examine it and link it directly to intelligence. The knowledge and technology just isn't there. It would be better to examine how people perform certain tasks like in the German paper on sexual images and working memory we discussed on the first page.
