Interesting Information

[thunderhead777]

I'm not sure how much propylene glycol vapor exists within a single puff from an E-Cig, but here's some interesting information about part of what we're breathing with these things. (Excerpt from article)

From the Department of Medicine, the Douglas Smith Foundation for Medical Research, the Bartlett Memorial Fund, and the Zoller Memorial Dental Clinic of the University of Chicago, Chicago

It has been found that propylene glycol vapor dispersed into the air of an enclosed space produces a marked and rapid bactericidal effect on microorganisms introduced into such an atmosphere in droplet form. Concentrations of 1 gm. of propylene glycol vapor in two to four million cc. of air produced immediate and complete sterilization of air into which pneumococci, streptococci, staphylococci, H. influenzae, and other microorganisms as well as influenza virus had been sprayed.

The article goes on:

Tests on possible deleterious effects of breathing propylene glycol containing atmospheres over long periods of time are being carried out.

That was 66 years ago - I wonder if the tests were ever completed

There is a thread here somewhere on the antimicrobial effects of PG. Strangely enough, it also seems to act against influenza viruses (tests to that effect have been carried out on mice).

I'd be interested in the mechanism of that, but suffice to say that monkeys kept in a PG vapour atmosphere have shown no ill effects and there seems to be no toxicity to mammalian cells.

Interesting compound, for sure.

I got the flu a day before I got my e-cig..... Go figure

Those World War II tests gained support in the report from Health New Zealand's Dr. Murray Laugesen on cartridge safety. They are true. They have never been refuted. Inhaling PG at the levels we do might actually be beneficial.
