A genetic analysis shows that the children of mothers who smoke harbor far more chemical modifications of their genome — known as epigenetic changes — than kids of non-smoking mothers. Many of these are on genes tied to addiction and fetal development. The finding may explain why the children of smokers continue to suffer health complications later in life.
