    VG CAN convert to acrolein (sp?) At high temps. Generally higher than any e_cig will provide, but some people seem to have issues with PG because of allergies...

    Whether you use PG or VG, you're still gonna be better off than if you keep smoking tobacco.

    Let's see what the EPA thinks about it.

    Seriously though this had to have been posted about a million times right?

    How about this one.

    http://www.news-medical.net/news/20091104/Propylene-glycol-in-e-cigarettes-might-keep-us-healthy-says-researchers.aspx


    "Propylene glycol, the primary ingredient in the electronic cigarette cartridge, may be a powerful deterrent against pneumonia, influenza, and other respiratory diseases when vaporized and inhaled according to a study by Dr. Oswald Hope Robertson. Decades before the e cigarette was invented, a study was conducted by Dr. Robertson of the University of Chicago's Billings Hospital in 1942 on inhalation of vaporized propylene glycol in laboratory mice. A more in-depth article was printed in the 1942 issue of TIME Magazine http://www.time.com/time/magazine/article/0,9171,932876,00.html for November 16th. "Dr. Robertson placed groups of mice in a chamber and sprayed its air first with propylene glycol, then with influenza virus. All the mice lived. Then he sprayed the chamber with virus alone. All the mice died."

    The researchers also found that "the propylene glycol itself was a potent germicide. One part of glycol in 2,000,000 parts of air would--within a few seconds--kill concentrations of air-suspended pneumococci, streptococci and other bacteria numbering millions to the cubic foot."

    Clinical trials on electronic cigarettes containing propylene glycol were carried out in New Zealand by Dr. Murray Laugeson of Health New Zealand and can be found on the website of SS Choice LLC at http://www.eCigarettesChoice.com under the tab "Media Coverage." Far from posing a threat to our health, the propylene glycol in e cigarettes might just keep us healthy. Further studies should be done on the effects of propylene glycol to determine if it can be used successfully as a virus prevention tool. Wouldn't it be wonderful if the best flu preventative was right under our noses all this time?"

    here's a few more for you just in case you are curious. look for these clinical trials and testimony in a raiders of the lost arc warehouse near you

    We will continue to get beat up over something that is virtually untested in the U.S. except by a cursory FDA test that mentioned dangers from being purchased by children and the chocolate and vanilla flavorings available. They also mentioned nitrosamines but didn't mention that they were just above the level of detection, not sky high like in analogs.

    PG is commonly used in the medical profession for asthma inhalers and intravenous medicines. I bought a bottle of sno-cone liquid the other day and guess what is on the label? Wait for it ... propylene glycol! The kids are already getting it. Yes, I'm a label reader. It's probably used as a thickening agent and it is in some salad dressings. I can just picture someone in a restaurant complaining that "Propylene glycol is in those e-cigs! That's a component of anti-freeze!", while he pours salad dressing on his lettuce...

    If it looks like a duck and walks like a duck, it must be a duck...
    It it is white, has a filter thingy, and the guy blows smoke, it must be a ..... (insufficient evidence).
