AOL - A chemical commonly found in vapes could harm unborn babies, scientists have warned.
Researchers at the University of California, Riverside (UCR) have urged the NHS to warn pregnant women after finding that vanillin, a common flavouring in e-cigarettes, could impair foetal development.
They examined the impact of the chemical on embryonic stem cells which can develop into any cell and are found in every part of a developing body as it becomes an embryo and then a foetus.
