(IsraelNN.com) Extensive Israeli research, that included over 20 thousand subjects, found that those who smoked a pack a day or more had a lower IQ by 7.5 points than non-smokers.I wonder if the cause of this is because people with lowers IQ's tend to become smokers or if smoking lowers the IQ, like some head injuries.
Investigator, Dr. Mark Weiser and his colleagues at the Sheba Medical Center in Tel Hashomer sought to examine the link between smoking and IQ among 20,211 boys aged 18 about to enlist in the IDF. They found that those who smoked had significantly lower IQ scores than those who do not smoke. These results remained consistent even after the researchers removed variables that could skew the results such as socioeconomic status or years of schooling.
Smoking Makes You Stupid. Wow!
If there ever was a good argument against smoking, this better be it.

Nowadays it's harder to tell but traditionally smoking was equally prevalent across the spectrum of social classes and income.
There are certain groups that are more likely to smoke, like people with mental illness and those in lower socioeconomic brackets but that's more a recent phenomenon given society's continued push to outlaw the habit.
