Dubious claims re:"water vapor"

[space0matic]

maybe you can look for the answer into the FDA (Food and drugs association) that control all stuff about it, as I know the "vapor" is already measured, http://www.fda.gov/downloads/Drugs/ScienceResearch/UCM173250.pdfcould be useful for u, a bit technical but enough to demostrate that water vapor is only one part, obviusly the toxic sustances are nothing compare with the common cigarette :S

I am probably missing something here, but does this PDF measure the exhaled amount of chemicals?

eta: I, personally tell people it's vapor. Just plain old vapor.

Not to be pedantic, but looking at the MSDS here: http://www.dow.com/webapps/msds/ShowPDF.aspx?id=090003e88019d0a9 PG is flammable as a vapor in concentrations between 2.6 and 12.5% by volume with an auto ignition temperature of 400 deg. C

I don't ask if I can vape..I ask..mind if I use my steamer??

I read through that sheet and it doesn't appear to be a "controlled product" or something of great concern. I don't see the battery heating it up to 400 degrees. Now if you have bottles containing it in your kit and your house is burning down it may act as an accelerant but so will a lot of other things in your house. That only leaves the concentration that is exhaled. How do they measure that? I'm sure it depends on the blend of PG and VG. Say... the highest blend of PG in a mix?

Someone correct me if Im wrong here...but isnt PG one of the primary components used in "Nebulizers" used by respiratory therapists in the medical world??

If the answer is yes..they at least we can tell people its the same stuff used for repiratory therapy.. just sayin...

I have seen a number of websites and YouTube vids that claim that vaporizers produce water vapor. Since our PVs are boiling PG or VG, it is only logical that they produce PG or VG vapor. The only way to get water is to burn the juice (read open flame) or heat it to the point where the chemical bonds break. Even then you would get lactic acid, oxalic acid, and other decomposition products.

So, ecigs don't produce water vapor.

Discuss...

Said claims have always been mostly incorrect, and based no methodology.

That said, consider the chemical composition of both PG and VG. Mostly O and H, which will separate and rejoin as H2O. With that some carbon, whatever is in the flavor, and nicotine. Most understand this. Anyone who says otherwise hasn't checked facts, or is just regurgitation the same old BS. Not unlike urban legends that won't go away; and no, the great wall can not be seen from space.

So, I'm willing to establish that my exhale is not water. Worth noting is the nicotine is attached to the vapor, it's not gaseous. As soon as the carrier cools, it drops. The longevity of that nicotine as well as the the other solids is brief.

But let's cut to the chase. As one of the many ex-smokers here, I care more about what I'm not inhaling/exhaling than what I am now. The reports above don't include cyanid and industrial solvents and a myriad of other crap. And I feel be better for it.

The nothing but water is an urban legend, but it's not all that far from being accurate. Regardelles, the residuals from my current output are far better than the output of my former smoke, camel wides.

Sometimes perfection is a difficult battle, and the lesser of all the evils is the best route.
