Tobacco exposure ups behavioural issues and dropout rates in children

  Children exposed to tobacco smoke in early childhood adopt anti-social behaviour, engage in proactive and reactive aggression, and face conduct problems at school, even drop out at age 12, a research has showed. Exposure to tobacco smoke is toxic to the developing brain at a time when it is most vulnerable to environment input, the researchers said. ‘Young children have little control over their exposure to household tobacco smoke, which is considered toxic to the brain at a time when its development is exponential,’ said lead author and Professor Linda Pagani from the University of Montreal in Quebec, Canada. Parents who smoke near their children often inadvertently expose them to second- and third-hand smoke. Abnormal brain development can result from chronic or transient exposure to toxic chemicals and gases in second-hand tobacco smoke. These compounds eventually solidify and create third-hand smoke. In the study, the researchers found compelling evidence that suggests other dangers to developing brain systems that govern behavioural decisions, social and emotional life as well as cognitiv (Read More: Not only alcohol, these factors too increase risk of liver disease!)
