"We're told that e-cigs that use 5-volts or more turn out to be only about 20-percent of what's sold here at Duay's business, Tiger Vapes in Shreveport. She also questioned the methods and conclusions of that new study.
"It's from one study off of one product, when I have studies that show 16-different products with 50-percent less than a traditional cigarette has in it," added Duay."

From Dr. Michael Siegel's blog:
"Based on calculations by Dr. Konstantinos Farsalinos from data provided in the article, the resistance was no higher than 1.7 ohms. At a voltage of 5.0V, the wattage would be 14.7W. That is in the "red zone" where the vaporizer is being overheated and where, for a conventional e-cigarette, the coils would likely be damaged or burned.
Essentially, what this study demonstrates is that if you overheat a vaping system, it will produce high levels of formaldehyde. However, such conditions are not realistic, as they could not be tolerated by an actual vaper. Therefore, extrapolating from this study to a lifetime of vaping is meaningless."
So the vape shop owners either have never taken a dry hit before or that part was conveniently edited out by the media outlet.
I have a homemade 120 watt raptor box that is set to 5.5 volts but I run it at .4 ohms (75 watts) and That's my sweet spot for max VG dripper use.
Without a dry hit everything runs smooth.
I can not or would not even attempt to take a 4 second puff! (The "puff" length used in the study)
I SOAK my drippers and think I may have gotten 3 dry hits in my 2 1/2 years of vaping.
The point is:
If you fire any mod at any voltage with barely any juice on the coil the smoking machine they use to collect info will find all types of bad shit.
Shit that no one in the real world would ever inhale!!!
But if everyone keeps saying 5 volts is the magic number I can see vaporizers in our future that are not allowed to go above 4.2 volts by law.
That would mean we would be back to actually having to modify our mods in order to vape happily!
EDIT: By Dr Farsalinos
"the authors used a top-coil CE4 atomizer "
Well that explains everything!
