Concerns raised over chemical used in vape fluid
Summary
A study led by Professor Prue Talbot at the University of California, Riverside, exposed embryonic stem cells to vanillin, a flavoring commonly used in e‑cigarettes, and found that even low nanomolar concentrations impair the cells’ ability to differentiate and can cause cell death. The researchers say these levels are relevant to maternal exposure from vaping during pregnancy, urging clinicians to warn pregnant women and regulators to require mandatory ingredient disclosure on vape packaging. Commentators, including Jacob George of the University of Dundee and Marian Knight of Oxford, note the pre‑clinical nature of the findings and emphasize the need for further human studies and limits on flavored vape products.
