Boys who smoke in their early teens risk passing on damaged genes to their own children, leading to greater chances of them developing asthma, obesity and lung problems, according to a new study.

Scientists from the universities of Southampton and Bergen in Norway fear that vaping could cause similar inherited health issues.
