No, I reject your arguments on the assumption that you are probably rather young, and therefore a product of the "OMG! Teh drugs and teh booze will rot your brain!!!111one"-mentality that has been preached for the last few decades, in direct response to the perceived over-indulgence of controlled substances during the 60s and 70s.
Yes, we can probably see some differences in cells or activity in the brain of someone who has been a chronic abuser of mind-altering substances (Ok, then, what would these differences mean? How would we see them? You do know that a PET scan looks at a much higher level than the cellular one, right? Oh, wait, you have no idea what you're talking about).
We can probably even correlate that with a few points drop in IQ or some other random mental test (pulled that one out of your a$$).
But to assume that a person goes from "smart" to "stupid" because he spent his youth drinking and doing drugs is not an accepted scientific theory, but rather a crack-pot scare tactic taught to our kids in an effort to control them.
Yes, drugs are bad (mmm-kay) and so is the abuse of any substance (hell, too much water will kill you.) But there is no valid scientific study that says "if you do some drugs for a few years or drink heavily, it will cut your intelligence in half." If you want to make the argument that Bush is maybe
1-2% "less smart" (pulled that number out of your a$$)
than before his "wild days," then I might listen to your ramblings. But as long as you argue that the "malapropisms that constantly spew from his mouth" are due to his previous drinking habits and apparent "brain-damage," you will be ignored.
Hahaha.
Yeah, I am glad to see you making outrageous scientific claims on the basis of perceived conspiracy. Dale Dribble is that you?
No, I am not young, highly impressionable, nor brainwashed. I am, however, highly educated and familiar with PubMed.
In short I will tell you this: chronic alcohol abuse will lead to cirrhosis, which will kill your liver. It does basically the same thing to your brain. We're not talking 1-2%, as you claim, but whole shrinking and damaging of vital brain areas. Alcohol abuse, especially over 20 years, absolutely and definitely has significant impact on the brain. No ifs, ands, or buts about it. No guessing or making it up. No "slight, little, 1-2%" difference.
It kills your liver and it shrinks your brain.
If I didn't know any better I'd think you were one of those red staters who believe in some liberal conspiracy; the rabidly anti-intellectual kind which has no place for "facts" or "science." Instead you buy into some kind of conspiracy theory where we tell people that drugs and alcohol are bad - not because that is the objective, actual truth - but rather so that we can impose some liberal fear mongering on America's children. The drugs and booze will rot your brain - that is the truth.
If you are going to respond do so with actual evidence and stop making things up. You sound like an idiot to anyone who actually knows what they are talking about.
Here, then, relevant results:
Genes and gene expression in the brain of the alcoholic
Dodd PR, Foley PF, Buckley ST, Eckert AL, Innes DJ
Chronic alcoholism leads to localized brain damage, which is prominent in superior frontal cortex but mild in motor cortex. The likelihood of developing alcohol dependence is associated with genetic markers... Genotype may modulate amino acid transmission locally so as to mediate neuronal vulnerability. This has implications for the effectiveness of pharmacological interventions aimed at ameliorating brain damage and, possibly, dependence.
Using magnetic resonance imaging and diffusion tensor imaging to assess brain damage in alcoholics
Rosenbloom M, Sullivan EV, Pfefferbaum A
Brain imaging using conventional magnetic resonance imaging (MRI) has revealed that several brain structures in people with a history of chronic alcohol dependence are smaller in volume than the same brain structures in nonalcoholic control subjects. Areas that are particularly affected are the frontal lobes, which are involved in reasoning, judgment, and problem solving. Older people are especially vulnerable to the damaging effects of alcohol. It is unclear whether women show consistently more vulnerability to these changes in the brain than men do. In general, alcoholics evaluated before and after a period of abstinence show some recovery of tissue volume, whereas alcoholics evaluated again after continued drinking show further reductions in brain tissue volume. A new MR technique called diffusion tensor imaging (DTI) can aid in detecting the degradation of fibers (i.e., white matter) that carry information between brain cells (i.e., gray matter). With DTI, researchers studying alcoholics have been able to detect abnormalities in white matter not visible with conventional MRI. Ultimately DTI may be useful in elucidating the mechanisms that underlie macrostructural and functional brain changes seen with abstinence and relapse.
Cumulative lifelong alcohol consumption alters auditory brainstem potentials.

...The alcohol consumption of the head and neck tumor patients corresponded to high-risk, dangerous, and risky alcohol consumption behavior...
