I own a small ecig shop in Olympia, WA and spend much of my time meeting, and greeting, and helping our vaping customers.


However, about once a week, a person who smokes cigarettes visits our shop for information:  In almost every case, I hear the same thing;


  1. I smoke and I don't like it.
  2. I am interested in switching to vaping but I have heard some frightening things about it.
  3. They then list out some combination of the same concerns about the ecig vapor containing dangerous levels of:
    • Formaldehyde
    • Diacetyl
    • Heavy Metals


None of this is true, so I take the opportunity to explain where that information came from and the real science behind the matter. In every case, my customer finds great relief in the facts and proceeds to give vaping a try.


Today, in this message, I would like to share what I tell them about the formaldehyde scare.


About Formaldehyde


First and foremost, modern vaping devices do not generate formaldehyde.


The original misinformation came from the Center for Environmental Health (CEH), a rabid anti-vaping organization in California.




More recently, the New England Journal of Medicine released a similarly misleading article.


It’s a simple fact that you have to heat up a vaping device coil to over 600 degrees to produce formaldehyde, a temperature that produces such terrible tasting vapor that no one would continue to vape with the device. The testing by CEH was carried out at over 1000 degrees, and that fact was left out of the report.


Dr. Farsalinos is a cardiologist, working as a researcher at Onassis Cardiac Surgery Center in Athens, Greece as well as University Hospital Gasthuisberg in Leuven, Belgium. He had this to say about CEH’s study -



Clive Bates, the former head of the United Kingdom’s largest anti-smoking charity, Action on Smoking & Health, took exception to the New  England Journal of Medicine's flawed study on formaldehyde in this article -



Final Note

In past years eliquids contained mostly propylene glycol (PG) as a solvent. And yes, at extreme temperatures, (PG) will oxidize (break down) into formaldehyde and other carcinogens. However, due to improvements vaping technology, the percentage of PG in eliquid has declined significantly in favor of vegetable glycerin.

Most eliquids now have around 70% VG and 30% PG as solvents, and some use 100% VG. VG does not suffer the same oxidization problems as PG, and is considered safe by even the FDA for ingestion orally, transdermally, or through inhalation.


If you smoke and don’t really want to, and live in the Olympia area, come on down to our store.  We would love to help.
