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.
