According to this article smoking might not just damage your health, it may also make you less intelligent. A study has been carried out on 20,000 young adults. It found that young people who smoke regularly are found to have lower intelligence levels than those who do not smoke. In fact those who smoke a pack or more of cigarettes a day averaged an IQ seven and half points lower than those who didn’t smoke. A typical smoker aged between 18 to 21 years old was found to have an IQ of 94 in comparison to a non smoker of the same age who averaged 101. Those who smoked more than a pack a day had particularly low IQs of around 90.
