“What do the findings mean?” asks Dr. F. “It depends on how you want to look at it. The authors calculated the concentration of benzene in inhaled air, and report levels up to 5000 μg/m3 air (at dry puffs of course). Compared to the ambient levels of 1 μg/m3 of benzene, everyone would think that this is a disaster.
“But not really, this methodology suffers from a major problem. Humans take about 12 breaths per minute, i.e. 17,000 (thousand) breaths per 24 h. The volume of air inhaled in 24 h is 20 m3. So, the daily exposure to benzene from ambient air is 20 μg. Even if you assume that Subtank at 25 W with 5-second puffs represent realistic conditions (they are not), you need to consume 105 mL e-liquid per day in order to be exposed to the same levels of benzene as breathing ambient air. For the EVOD under normal vaping conditions, you need to vape 125 mL e-liquid per day.”
Wow, I know some heavy vapers, but none of them can handle 100 mL a day. I myself go through about 8-10 mL a day, which is about five times as much as I vaped before I had to sit at a desk and read junk like this study every day. But I digress.
“The press statement mentions that: ‘The power levels used in the study were still far below those accessible to users on some devices, which can exceed 200 watts.’ This statement is similar to saying that: ‘We crashed with a car in Trafalgar Square with a speed of 100 mph, but still that was far below the 150 mph speed that cars can reach.’,” wrote Dr. Farsalinos.
And there we have it. These geniuses have to go to unrealistic extremes to make their results sound scary enough to justify the millions they’ve received in government grants to produce scary e-cig science. If they simply tested normal products at the power levels vapers use them at, there would be nothing to report.
“I understand it is frustrating to desperately try to find a problem but fail,” concludes Dr. Farsalinos. “However, this still does not prevent the mispresentation of evidence and science.”
The Portland atty blazers aren’t interested in doing real science to learn about actual risks in vaping, or to find the true limits of safe wattage or low resistance. None of their work can be applied to real world vaping. They’re just publicity hounds, willing to do just about anything to get their names in the paper — even convince smokers that vaping is dangerous.
