Scientists Blast Hong Kong Vaping Study As Hot Air
An outrageous study from Hong Kong’s Baptist University found in the Daily Caller has made headlines by claiming that vaping products are a million more times harmful than Hong Kong’s air.
But this study, which has raised more than a few eyebrows among vaping researchers, has a problem — the results of the study are not supported by evidence. And the fact that the study has not released their methodology, which is required for validation, has earned the ire of one particular vaping expert.
Dr. Konstantinos Farsalinos, a cardiologist and research fellow at Onassis Cardiac Surgery Center in Greece, has blasted the report as void of any actual sound science. He has gone on record with his accusations that the scientists involved in the study are engaging in a misinformation campaign targeting the vaping industry.
Farsalinos points that the study focuses on the level of polycyclic aromatic hydrocarbons (PAH), which are found in combustible substances like gasoline or tobacco. While these findings may be correct in that the levels in e-cigarettes may be between 2.9 to 504.5 ng per millimeter, the finding has no bearing on vaping devices.
Why? Because there is no combustion at all when using a vape device. Vaping products work by heating a nicotine liquid and converting the liquid to vapor, which vapers then inhale. There is no fire or spark to light the substance on fire, like in traditional cigarettes. So the finding is null and void.
And, Farsalino continues, even if the PAH levels are correct, a quick search of Hong Kong’s air PAH levels show that daily exposure to Hong Kong’s air would result in a daily exposure of 960 ng.
Compare that with the 9 – 1500 ng that the study claims is in vaping products. The comparison shows that using a vaping device has 100 times less PAH levels than the daily exposure to Hong Kong’s air. This means the main claim is untrue.
Also slammed by Farsalinos is the idea that you could even compare smoking a cigarette to inhaling e-liquid. In fact, the PAH levels for a traditional cigarette — which has over 40 human carcinogens — far exceeds pollution in the air. So the study, he says, cannot equate one cigarette with 1 ml of e-juice.
Farsalinos, along with others in the vape research community, remain baffled by the study. And while it is possible that the scientists are far off the mark in their study, it seems that this study is a smear campaign with the intention to fear-monger the public. Only time will tell if the study holds up in the science community.
