Fresh concerns over chemical found in flavoured vape liquid
Researchers warn that vanillin in vape liquids may harm early human development.Summary
Researchers have raised fresh concerns about the safety of vanillin, a common flavouring additive in e-cigarettes, after laboratory tests indicated it could compromise core processes of early human development. The study, led by Professor Prue Talbot from the University of California Riverside, found that even minute concentrations of vanillin could cause embryonic stem cells to lose their ability to form distinct cell types, while higher amounts resulted in cell death. The authors argue that clinicians should counsel pregnant women about this potential harm and that regulatory bodies should consider requiring e-cigarette brands to list all ingredients on their packaging. While experts acknowledge the study's design, they note that the lab conditions differ from real-world exposure and that further clinical research is needed to confirm the findings.
