Smoking One Pack A Day Lowers IQ by 7 Points


Young smokers have lower intelligence than their non-smoking peers, according to a study by researchers at the Sheba Medical Center, Tel Hashomer, Israel.


Tests involved over 20,000 people between 18 and 21 years of age. An average smokers’ IQ was 94, while non-smokers scored 101. Those who smoked one pack a day and more had even lower IQ, at 90 points. Scientists say their findings show that smarter people are less likely to put their health at risk. Besides they assume that smoking causes oxidative stress, which is the damage of brain cells by oxidation.
