The American vaping community has grown very accustomed to reading intentionally misleading articles online that try to equate vaping with smoking. But did you know that there is a decades-old research study by a world-class scientist which claims that the propylene glycol vapor from vaping e-liquid kills deadly pneumonia-causing bacteria?
It’s true. The scientist’s name is Dr. Theodore T. Puck, and his research on this now-common e-liquid ingredient actually took place nearly 75 years ago between 1943 and 1945. When Mr. Puck died in 2005 at the ripe, old age of 89, newspapers from around the world, including the New York Times, ran full-page articles highlighting his remarkable achievements in scientific research, particularly in regards to genetics and cell growth.
His 1943-45 research entitled, The Bactericidal action of propylene glycol vapor on microorganisms suspended in air, is still readily available online, published in The U.S. National Library of Medicine at the National Institutes Health (NLB-NIH) organization.
Propylene glycol, pneumonia, and vaping
By reading Mr. Puck’s study, airborne bacteria including pneumococci, streptococci, and staphylococci are immediately killed when they interact with the heated vapor of propylene glycol (PG). Furthermore, the PG only needs to be heated to as little as 80 degrees Fahrenheit. Vaping typically takes place at almost four times that level.
Pneumococci is the bacteria most commonly associated with pneumonia. Streptococci causes strep throat, and staphylococci is perhaps best known as the bacteria that leads to food poisoning.
Yet doctors have known for decades that the vapor produced from heated propylene glycol kills these bacteria instantly. And according to Mr. Puck’s research, it doesn’t even require a massive amount of vapor.
“Pneumococci were killed by amounts of propylene glycol as low as 1 gm. in 20 million cc. of air. Concentrations of 1 to 5 million to 1 to 10 million were required to produce the same degree of killing of streptococci and staphylococci.”
So, why do federal agencies like the CDC and the FDA continue to demonize vaping? Why do they continue to publish misinformation online, making such outlandish accusations that vaping is just as deadly as smoking? Perhaps they need to re-read Mr. Puck’s research from 1945. Or perhaps even more ominously, they have already read it but refuse to share its scientific findings with the American people.
