RCSI team used AI modelling to predict hazards created as flavouring is heated for inhalation

The study by a team at the Royal College of Surgeons in Ireland and published in Scientific Reports used AI modelling to suggest that 127 damaging chemicals are potentially formed as devices heat liquid for inhalation. A further 153 harmful chemicals classified as “health hazards” and another 225 chemicals described as “irritants” may also be present.

“It would be reasonable to anticipate that lung exposure to a large number of chemical entities can only increase health risks,” states the study.Child dies after road incident in residential area in Ennis, Co Clare“The research team at RCSI University of Medicine and Health Sciences, used artificial intelligence to simulate the effects of heating all 180 known e-liquid flavour chemicals found in nicotine vapes,” said Professor Donal O’Shea, the study’s lead author.

“It is plausible that we are on the cusp of a new wave of chronic diseases that will emerge 15 to 20 years from now due to these exposures. We hope this research will help people make more informed choices and contribute to the conversation on the potential long-term health risks and the regulation of vaping, which this research suggests should be comprehensive.”
