Doctors believe that the decision to smoke is linked to a lower intellectual capacity. Research published in Britain suggests that smokers have lower IQs than non-smokers.
The researchers found that the lowest IQs were those who smoked more cigarettes per day. Besides causing damage to health are known, smoking also affects intellectual performance.
An article published in the British journal Addiction, “one of the most prestigious on smoking, highlights another risk factor, according to the survey, youth less intelligent are more likely to start smoking.
It was made a research with 20 thousand servicemen of the armed forces of Israel, aged between 18 and 21 years. The IQ of them was within the range considered normal, but, while non-smokers had a mean IQ of 101, those who smoked was 94.
The researchers found that the lowest IQs were those who smoked more cigarettes per day. A controversial conclusion.
The doctor Sergio Ricardo dos Santos notes that having parents or friends who smoke may be more decisive than the intelligence to the smoking habit. He remembers that the geniuses of music, like Mozart, were smoker. But he warned: the IQ of those who smoke may decrease with time.
