Published in the journal, the research demonstrated that giving
rats nicotine impaired the development of their growing foetus’s
lungs in a way consistent with asthma. But they also found that
those foetus’s eventual offspring, who had not themselves been
exposed to nicotine, were affected.
Epigenetic makers may be the mechanism behind how
nicotine-induced stems are transmitted from one generation to
There was another possibility-that the effects on the second
generation’s came about as a consequences of direct toxic
influences on the first generation's reproductive organs.
The problem is in the pregnant mother. In the baby are already
the cells that are going to make the next generation. You’ve
always got three generations in one. They will be exposed to
some extent by the direct effects of nicotine.
