This technology is not new , nor is the use of Propylene Glycol in the Health Care Industry. Non-toxic anti-microbial. Used since 1942 for mobile surgical theaters and for decades in nebulizers.
Researchers have shown that one part of glycol in 2,000,000 parts of air, within a few seconds, kill concentrations of air-suspended pneumococci, streptococci and other bacteria numbering millions to the cubic meter. Another study also showed complete protection from Influenza for lab mice.
There is great promise in using PG as a local,
non-antibiotic treatment for pulmonary infections.
Anecdotally, I used to have one episode of Bronchitis and one of Tonsillitis per year, during my 25 years as a smoker. I have yet to have any since vaping June 2014. This is a very common occurrence when discussing health issues on 'Vaping Forums' I hope that at some point, when hundreds or thousands of people have the same experiences, it will be considered evidence.
Try a social experiment. Ask people who have recently stopped smoking and used the 'government approved' methods of quitting "Do you think you will have another cigarette in your life?"
Answer is never definitive. Always some element of 'I hope so' 'maybe'
Ask the same question to a Vaper. You may be very surprised by the consistent replies you get.
Tobacco is the contributing factor for many diseases and death.
I honestly can't understand why the Medical Community is not championing this. I understand politicians have two huge lobbies to 'contend with' and a huge loss in taxation to resolve.
Drugs like Champix and others that radically change one's neural chemistry are approved for use ... and all NRT products are sold OTC due to the <4mg provision in the Prescription Drug Act. Even the highest concentrated Nicotine 'eJuice' is 50-100x lower per dose than OTC limits. As one inhalation is a dose.
Nicotine is classified as an insecticide. A family of plants produced it as a defense mechanism. I have performed many 'cloud chamber' experiments and had zero success in harming or killing any insect. They have the disadvantage of having every cell respirated to the outside (to deliver oxygen to mitochondria without lungs or blood) This makes them extremely susceptible to topical and gaseous toxins. The likelihood of a human absorbing nicotine with 1/100,000th the exposure, and protection of the skin, is nil.
The WHO report only states that 'not enough studies, tech evolving too fast for regulation, quality control for eLiquid' They reference studies that were inherently flawed. For example, doing gas chromatography on vapour that was superheated beyond 'normal device usage limits' and also burning the wick. Something no sane person would do when utilizing ENDS.
I personally blend everything I Vape. All ordered from laboratory supply with full MSDS sheets. There was some vaping community panic of diacetyl from butter-like flavours, which has caused most flavour vendors to reformulate. More famously, it has created a ban on microwave popcorn many places and the closure of many manufacturing facilities related to that food industry.
Will leave with some links to reputable sources and studies.
I thank you for your time in reading this.
