wow...my first post is a serious one!

I don't know if you've already seen this,but I tought u may find it interesting...basically,it's a comparative test between traditional cig and ecig effects on living tissue cells...
enjoy!

Certainly interesting, but I think I`ll wait for someone more scientifically inclined to condense that lot into more digestible points !

To me basically they do not know because they used cartridges which ran out of juice. Their machines puffed it too fast, too many times. However, their later test of 50 puffs show no toxic effects. It's a very basic, preliminary study. As noted in there they need to use proper controls, a tank system so it doesn't run out, longer times between puffs etc basically how we use them. What got me is they used vape wizard as one of their tests, I hope they're not just filling up a cartridge full of that, you only need a couple of drops in a 30ml bottle of juice! But going by their 50 puffs (keep it wet) method it showed less if no toxic effects, so that is promising.

To sum up, keep it wet folks!

Very interesting, Thanks for sharing.

Although interesting the results of this are not too helpful, too many errors and excuses. As CP states it is a preliminary experiment.

The graphs do seem to show that the first 50 puffs on the cartridge for all samples would not be classified as toxic. For a standard 510 cart fifty, three second draws is a lot to expect most likely it ran dry a fair length of time before then and the filler was beginning to degrade hence the increase in toxicity.

It is also not clear whether the apparatus cleared the flask of vapour between 'inhales' the same way as we would take some breaths between draws if it didn't this could also account for an increase in toxicity.

Overall brilliant this testing is being done but improvement to the experiment need to be done before we can trust or cite the results. The main point we can take from this is all eliquid samples were significantly less toxic than the tobacco control.

I read the article as dont run dry and dont dry burn, which we know.

[steffijade]

I think this has been mentioned before in another thread, but how many people would vape a full cart with the ecig in a fully inverted position? Mouthful of juice anyone?

[throathit]

I can still ride my mountain bike hard for a long time and when I smoked it had me gasping and ready to quit or die. Not saying vaping is good for ones health but alot better than burning the evil weedy one. I'm sure after a lot of testing and time we will find out just that. It's the flavours that bother me most with so many chemicals in them the effects must be hard to follow. I feel quite sorry for the poor person who has to do all the work to find out just what happens to all that ry4 inside of us. I for one will be first in line for any tests the testers would like to do.

The flavours were added at 1-3% ish (it varied depending on the flavouring). I'd particularly like to see Perique Black re-tested as that was the flavouring that showed the highest toxicity in the original (flawed) tests. And it's one that I use (in tiny quantities). Weird thing is though, even with the 120 puffs, some flavours did not show any signs of toxicity.

So in conclusion if I read it correctly, some flavours were just as or more toxic as a tobacco cigarette when overheated due to the filler running dry and when it didn't run dry there was no toxicity.

[Harlequin69]

Pretty much Googled I think we can assume the residue on the coil is being burnt off and possibly overheat plastics causing the increase in toxicity to approach and in one case exceed tobacco. The thing about that aspiration machine is it doesn't have a bad taste sensor and will happily continue to 'puff' away long after a human would have gone 'Urrgghhhh dry hit!' and realised the cart needs topping up.

Edit: Things we don't know: Who is this guy? A student or a professor or a researcher?, Where is this being performed and who commissioned it? Basically I am treating this with suspicion until a further study from a recognisable institution is published.

I think the person who wrote the report at the beginning is a medical doctor and vaper. The studies were commissioned by Flavourart. They are being performed by Dr. Elena Bocchietto, a Biologist and biotechnology specialist at ABICH S.r.l.

Really good to see somebody at least making attempts at gathering scientific data.

For the above experiment, maybe they should have compared it with smoking the filter butt of a normal cigarette. Probably the same as dry burning an upside down ecig or whatever they had going there.

[PapaLazarou]

I'm not sure what possessed them to think that 120 drags from a standard 510 cartridge would be a good idea.

[googled]

just did a quick test using a new 510 atty, a very well soaked standard cart and primed atty. I managed 34 3 second drags before it became horrible. It was an LR atty though since I have no standard resistance.
