Ecigs create dangerous formaldehyde - a new study

[Colonelboom]

Yes but no but, yes but no but..

So the long and short of it is that if you are using a subtank at 25 watts you will start exposing yourself to dangerous levels of aldehydes when you polish off the 409th ml in a day... Run for the hills, it's dangerous I tell thee.

Hahaha. Whether they produce formaldehyde or not can't be anywhere near the levels produced by cigarettes!

When are these "scientists" going to opt for the easy way out and just do a simple, side by side, comparison of a lung full (by volume) of cigarettes smoke, and a lung full (by volume) of e-cig vapour, tabulate a list of the chemical components of each, their volumes, and their toxicities, and put the lid on this fools errand for good?

oh bollox, id better slow down on my V1 custard then.

nasties + embalming fluid. what next.

In this case it makes sense to not do a comparison to tobacco as its a quantitive test rather than qualitive. The aim was to show in minute detail the levels between the different types of device and show pretty well that the newer types of coils have improved wicking methods that would plague the likes of the CE4 and create aldehydes.

Someone will be along at some stage I am sure to extrapolate the data into a cig vs ecig comparison

...extrapolate...

Is that one of @MrTeaTime 's hobbies?

They'll do that when they cease needing any funding, and don't want to do any more experiments. I doubt that will be any time soon, so expect lots more of the same!

If i read it right think it's saying use a cheapo ecig at your peril but create clouds for fun on your subtank.

Yeah, I've carefully read this article now. It's stating that the level of formaldehyde from a subtank at 25watts is about 50-100 times lower in a day that smoking a pack of cigarettes. Furthermore, this is a worst case scenario for a couple of reasons. The main reason is the way they calculate (actually, extrapolate would be more apt) the amount of formaldehyde from a day of vaping. They take the amount of formaldehyde present in the vapour per mg and then multiply this by the number of mg that an average user would fill their tank with in a day. This assumes that we absorb every last bit of juice we put in our tank. This is a bold assumption, because I'm pretty sure I breath most of it out after exhale for a start!

Also, acceptable occupational health levels of formaldehyde is apparently over 5mg a day! Watch out factory workers!

In short, this research looks more like it was funded by kangertech than by anyone else.

Please post a reply if you read the paper and think I've made a mistake.

NOTE: Their conversation at the end of the paper, where they don't understand why some devices are producing lower vapour yields at higher wattages, is amusing. They guess it's because of wicking issues; too right! Most likely they've destroyed the wick and/or gunked the coil to the point it won't function.
