Smoking: Not Smart
According to research findings released in 2004, smokers and former smokers did not perform as well on tests as nonsmokers. Four hundred sixty-five subjects had taken a test that measured cognitive ability in 1947 at age 11. They took the test again between 2000 and 2004. Based on the results, smoking appeared to cause a one percent drop in cognitive function. A possible explanation for this correlation is that smoking-related lung damage caused less oxygen to reach people’s brains.
