In a study of 20,000 adolescent smokers, found that those who regularly smoked per day decreased their level of intelligence than non-smokers. The study also concluded, the more a person smoked, the lower the IQ, or level of their intelligence.
Daily Mail, Monday (29/3/2010) launch, those who inhale a pack or more every day, has an IQ of seven and a half points lower than those who do not smoke. Smokers aged 18 to 21 years had an average IQ of 94. While those who do not smoke the average-IQ 101.Studi also mentioned, those who suck more than one pack of cigarettes per day had an average IQ of 90.
Dr. Mark Weiser who led the study says, he and his team had not found the obvious reason that smoking causes a decrease in the level of intelligence. "It is still required further study to really prove its legitimacy," said Weiser.
"But here is very clear that people had low IQ on average choose to smoke. This is not just related to socio-economic status, but it can also because of their educational levels affect their decision to smoke," he explained.
He is also suspected, this conclusion confirms the results of previous studies, that those who have lower levels of intelligence tend to make decisions that are not 'smart' associated with their health.
