The study, which was carried out at the University of Montreal in Canada, found that even brief periods of passive smoking have been found to cause lasting damage to the brains of children under the age of 10.
Dr Linda Pagani and Dr Caroline Fitzpatrick from the university said that children who came into contact with second-hand smoke are more to likely develop deviant behavioural characteristics. These finding were regardless of whether their mothers smoked while they were pregnant or their parents had a history of anti-social behaviour.
The study is based on research that found 'sidestream' smoke can be more toxic than 'mainstream' smoke exhaled by the smoker. Second-hand smoke comprises 85% sidestream smoke, which comes straight from a burning cigarette, and the remaining 15% is inhaled and then exhaled mainstream smoke. Sidestream smoke is considered more toxic than mainstream smoke because it contains a higher concentration of many dispersed respirable pollutants over a longer period of exposure.
Writing in the Journal of Epidemiology and Community Health, Dr Pagani said: “Exposure to this smoke at early childhood is particularly dangerous, as the child's brain is still developing.
“I looked at data that was collected from about 2,055 kids from their birth until ten years of age, including parent reports about second-hand smoke exposure and from teachers and children themselves about classroom behaviour.
“Those having been exposed to second-hand smoke, even temporarily, were much more likely to report themselves as being more aggressive by time they finished fourth grade (year five).”
The doctor added that “the starvation of oxygen caused by smoke exposure in the developing central nervous system can cause low birth weight and slowed fetal brain growth”, explaining that “Environmental sources of tobacco smoke represent the most passive and preventable cause of disease and disability.”

New Warnings Over Second-Hand Smoke For Babies
New research has found that babies and young children forced to breathe second-hand cigarette smoke are more likely to be aggressive and anti-social as adults.The study, which was carried out at the University of Montreal in Canada, found that even brief periods of passive smoking have been found to cause lasting damage to the brains of children under the age of 10.
Dr Linda Pagani and Dr Caroline Fitzpatrick from the university said that children who came into contact with second-hand smoke are more to likely develop deviant behavioural characteristics.
