Smoking makes you stupid?

          Researchers in Israel (Tel Aviv University) tested that 28% of 20,000 men smoked, 3% were former smokers and 68% had never smoked. te article says that "The average IQ of the smokers was 94, compared with 101 among the non-smokers. Men who smoked more than a pack of cigarettes a day had an average IQ of 90." Even the twins that they tested had the same result. The twin who smokes has a lower IQ than the other who does not.

          The researchers' study could not prove smoking is the reason for people having low IQ or having a lower IQ predisposed people to smoke but they did not count off the possibility that social and economical status produces both smoking and lower IQ.

Either way, smoking is still dangerous for your health and the people's health around you.
