I have seen that before. I was just curious on more of the fruit flavors. Cause that study doesn't show barely any of the flavors they have
Sadly, they also really went overboard (not), using V2 e-cigs.... which is not exactly representative of some of the modern e-cig power levels.
Regardless, a 40ng formaldehyde result on a low-ish power device might equate to a 400ng using a 75 watt device.
E-cig = 400ng
Cigarette = 29,000ng
72 times more formaldehyde in an cigarette than a high power
vaping device! I call that one heck of a result in favour of
vaping compared to smoking.
