Aug. 2, 2022 – “Our data support the regulation of flavor chemicals and synthetic coolants in Puff ECs to limit their potentially harmful health effects,” said Esther Omaiye, a former graduate student in the Environmental Toxicology Graduate Program and the first author of the research paper. “The high levels of nicotine, flavor chemicals, and synthetic coolants in Puff ECs, which exceed those used in other consumer products, bring into question the safety of Puff products.”
Prue Talbot, in whose lab Omaiye now works as postdoctoral researcher, said one area of regulatory concern with respect to ECs is the evolving use of novel chemicals in e-cigarette fluids.
“For years, we have been aware that EC designs are evolving,” said Talbot, a professor of cell biology who led the research team. “Only recently have we also realized that the chemicals used in EC liquids are likewise changing. These changes usually make the EC product more attractive to adolescents or attempt to circumvent FDA regulation — for example by using synthetic nicotine in lieu of tobacco derived nicotine to escape FDA regulation.”
