Long-Term Smokers Suffer Lowered IQs

10/12/2005

Long-term smoking hinders mental speed and accuracy, according to a new study that finds that chronic smokers experience a decline in their IQ scores.

Medical News Today reported Oct. 11 that researchers from the University of Michigan measured the IQ scores of 172 alcoholic and nonalcoholic men. They found that alcohol consumption caused thinking problems and lowered IQs, but also discovered that long-term smoking had similar effects -- even among men who don't have alcohol problems.

Alcoholic Smokers Lose More Brain Mass

9/30/2005

All alcoholics are known to lose some brain mass, but those who also smoke lose more than nonsmokers, Medical Study News reported Sept. 28.

Researchers at the San Francisco VA Medical Center found that the more that alcoholics smoked, the more brain mass they lost, notably in gray matter in the parietal and temporal lobes. An estimated 50 to 90 percent of alcoholics smoke, researchers noted.

No similar differences were found between smoking and nonsmoking light drinkers involved in the study.

I smoke and it don't do me no harm....

Seriously, I think there are too many other factors.
For instance, is smoking more prevalent amongst those from a lower social class?
More prevalent amongst those with less education?
Are stroke victims with impaired mental abilities who smoke being used as test subjects?
One would have to eliminate many factors before conclusions could be drawn.

AFAIK, alcohol kills brain cells which is why it can lower intelligence.
I don't recall Nicotine having the same effect. If anything, it encourages brain cells to create more receptor sites (which is why it may prevent Parkinson's Disease).
Possibly it could be linked to decreased oxygen levels in the blood?

The Irish are one of the most ancient nations that I know of at this end of the world, and are from as mighty a race as the world ever brought forth.
For it is certain that Ireland hath had the use of letters very anciently and long before England; that they had letters anciently is nothing doubtful, for the Saxons of England are said to have their letters and learning, and learned men, from the Irish.
- Edmund Spenser (writer, and British Government Official in Ireland, AD 1596).

The renaissance began in Ireland seven hundred years before it was known in Italy. And Armagh, the ecclesiastical capital of Ireland, was at one time the metropolis of civilisation.
- Arsene Darmesteter, Professor of Old French and Literature

Ireland can indeed lay claim to a great past; she can not only boast of having been the birthplace and abode of high culture in the fifth and sixth centuries . . . but also of having made strenous efforts in the seventh and up to the tenth century to spread her learning among the German and Romance peoples, thus forming the actual fountain of our present continental civilisation.
