Second hand smoke e-cig compared to regular cigarette smoke

[Diche]

You make it sound like they had an agenda.

I certainly think the journal article had an agenda, not so sure about the scientists conducting the experiments. They tested (not sure how well) one brand of cartomiser style cigalike which I have never heard of before and which is certainly not as common as the journal article would suggest from the responses to my Google search. They found that the emissions were free from cancer causing PHA's but had elevated levels of Nickle and Silver. They came to the conclusion that these metals were not introduced to the emissions from the e-juice, but a by product of the heating coil or filler.

An interesting study, but of little relevance to my personal vaping experience as with the type of device I use the components are e-juice, organic cotton wool and kanthal wire which is an iron-chromium-aluminium alloy and therefore unlikely to be a source of the elements that concerned the researchers in this study.

Chromium I think was one of the emissions noted but can't remember if was higher from smoke or ecig emissions anyway...

Oh yeah... found it toxic metal chromium present in ecig emissions but not in cigarette smoke... no mention of any harmful quantity or not... but as far as I can tell from other studies no harmful levels of any toxins...

That is weird because by my reading of the tables in the pdf exactly the opposite was true. The ng/m3 of Cr was highest in the outdoor measurements and lowest in the ecig test. Odd as I really would expect it to be a component of ecig vapour.

edit: no it was lower in the normal cigarette test, but still significantly lower in ecigs than in the enviroment they used as a baseline

Hmm... couldn't read tables as too small on my phone... am going from body of article... and that's what it says... chromium in large quantities is a product of car exhaust though I think. .. so higher outdoor quantity would make sense... Diche

Yeah that would make sense, I edited above as I didn't read it quite right first time. Chemistry is really not my subject, I am having to look up the letter codes for the elements as I am ashamed to say I do not know my periodic table. I have a basic understanding of chemistry, but nothing spectacular.

Diche I can never remember any of the table stuff... dates...names... etc. .. but am occasionally a mine of useless bits of info...

Ahh a kindred spirit lol

i couldnt face reading it. second hand vapour maybe i would try. but when there is no first hand smoke to produce any second hand smoke? instant no way i was arsed enough to try

Yeah that is a bias introduced by the journalist writing the article, the original paper has no mention of smoke in the title
'Particulate Metals and Organic Compounds from Electronic and Tobacco-containing Cigarettes: Comparison of Emission Rates and Secondhand Exposure '
