While research into possible risks from flavors is a good thing, based on this study, it's woefully premature for the study author to claim it's "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" and for media headlines to proclaim the study found there are "hazardous health risks from flavoured vapes."
First of all, there are already hundreds of thousands of adults who have already been nicotine vaping for 15 - 20 years in the U.S., without any sign of a "new wave of chronic diseases." Why don't researchers want to speak to any of those folks?
Secondly, the paper leaves a LOT of unanswered questions:
- At what temperature did the models given to the AI result in decomposition? Are those temperatures common in real-life vaping?
- Was the fact that the flavors are typically diluted in a base liquid of vegetable glycerin and/or propylene glycol factored into the models? People aren't vaping the flavor chemicals at full-strength, yet a word search of the study didn't find any reference to base liquids containing "vegetable glycerin" or "propylene glycol." It would be good to know what effect, if any, the base liquid has on the decomposition of the flavor chemicals.
- Is this modeled on real-life vaping practices? It generally takes time for chemicals to "break down" from being heated, yet "puff" times are typically just 3-5 seconds long.
It seems, once again, that the media and anti-vaping researchers are irresponsibly stoking the flames of hysteria over scant evidence and risking the lives of millions of people who might be convinced by the scaremongering to just keep smoking.
The research team in RCSI’s Department of Chemistry used artificial intelligence (AI) to simulate the effects of heating e-liquid flavour chemicals found in nicotine vapes. Lead author Professor Donal O’Shea, RCSI Professor of Chemistry and Head of Department, said the findings are very...
