*Children whose Grandmothers smoked were more than twice as likely (2.1 times) to develop asthma.
*Even if the childs mother did not smoke while she was pregnant - but the child's grandmother did - the child has nearly double the risk (1.8 times) of developing asthma.
*If both the mother and grandmother smoked while pregnant, a child is more than two - and - a - half times more likely to develop asthma.
Chemicals from tobacco can affect in two ways. a) If the child is a girl, her eggs may be affected putting future children at risk. b) The foetus' DNA in the mitochondra may be damaged through subtle changes in which genes are turned on or off and transmitted through the maternal line.
It is these alterations which decrease the bodys immune function and reduce the body's ability to rid itself of toxins, thus increasing the risk of asthma in smokers' children and grandchildren.

That is most interesting as my mother never ever smoked and I have asthma and we could never figure out the link? But my grandmother was an extremely heavy smoker. Thanks for that Florrie.
