Are There Really Dangerous ECigarette Chemicals?

There’s a great deal of concern regarding the ingredients in electronic cigarettes, especially since there are many conflicting reports flooding the media about the chemical makeup of e-liquids. 

If you smoke and are considering switching to electronic cigarettes you may be wondering if they’re even worth a try.

Many are asking,“Why should I experiment with something that may be just as dangerous as tobacco?”

This article will help to answer those questions.

There’s lots to say about electronic cigarette safety, but since you probably Googled Chemicals or Ingredients in E-Cigarettes we’ll start by addressing that question.

Here are the Facts About E-cigarette Chemicals 

What Are the Ingredients in an E-Cigarette?

Any respectable electronic cigarette company’s website will offer a page that lists these ingredients.  

This statement was taken from V2Cigs. 

Ingredients; Vegetable glycerine (USP Grade), food grade flavorings, propylene glycol (USP Grade) and nicotine. (The 0% strength contain no nicotine). 

Propylene Glycol is the preferred e-cig ingredient base used to dilute and vaporize V2Cigs pharmaceutical-grade nicotine liquid.

fda logoPropylene Glycol (PG) is an FDA approved food additive used in everything from cake mixes to asthma inhalers. It is also found in nasal sprays such as Afrin; oral, injectable and topical pharmaceuticals, and beauty products such as lipstick, creams and lubricants including baby wipes. PG is in candies such as Gummy Bears.  It is sometimes used in non-toxic antifreeze. 

Note: Antifreeze, in an of itself, is not an ingredient in e-cigarette liquids.

Some people are under the impression that Propylene Glycol and Vegetable Glycerine are oils, but they are not. Both are water soluble solutions.

E-Cigarettes come in many flavors, so of course there are other USP Grade ingredients which vary with the flavors. 

UPDATE: Here’s the latest information about Diacetyl, Acetyl Propionyl and Acetoin

A 2015 study made sensational headlines when it was reported that some e-liquids contained diacetyl, a chemical that could cause bronchitis obliterans, or “popcorn lung”. Acetyl Propionyl and Acetoin were also cited.

The now notorious study did not find any of the above ingredients at harmful levels in e-cigarettes and the study has since been debunked by research scientists including one of the world’s most renowned, Dr. Konstantinos E. Farsalinos. 


The tests were NOT performed using standard e-cigarettes; they were using modified high wattage devices designed to be more like miniature stage-type fog machines. 

Diacetyl has been known to cause bronchitis obliterans (popcorn lung) in factory workers. Out of the thousands of factory workers who were tested, only a tiny fraction of 1% (eight people to be precise) are alleged to have come down with bronchitis obliterans.

In other words, even if you breathe massive amounts of airborne diacetyl (thousands of times more than any vapor product could expose you to), all day every day for a decade or more, it’s still overwhelmingly unlikely you’re going to get “popcorn lung.”

The study never mentioned that tobacco has more than 100 times the diacetyl then the absolute worst e-cig (750 times the average one). Tobacco isn’t considered a risk factor for popcorn lung.

The Vapor Industry’s Response

There was an extremely fast reaction on the part of e-liquid companies when the issues with flavorings containing diacetyl came to light. All companies either pulled the line that had that flavoring or reformulated those e-liquids. 

Here Are the Ingredients Typically Found in Tobacco-Flavored E-Cigarettes:

  • Ethyl Maltol- an organic compound that is common flavorant in some confectioneries.
  • Beta-Damascenone- a food grade flavoring used in wines and other foods requiring a floral essence.
  • Vanillin- Used in ice cream, baked goods, medicines and many other products that require a vanilla taste or aroma, it is an organic crystal that forms on the outside of the vanilla bean.
  • Trimethylpyrazine- An FDA approved flavoring used in caramel chocolate cocoa and coffee 

Menthol Flavored Ecigs Also Contain These Ingredients:

  • Menthol- an organic compound that occurs naturally in mint and some other plants.
  • Menthone- a naturally occurring organic compound and a constituent of the essential oils of pennyroyal, peppermint, Mentha arvensis, Pelargonium geraniums, and others.
  • Cineole- is a natural substance found in eucalyptus and other essential oils. It has a pungent, spicy, cooling taste and is know to have anti-inflammatory properties.

Other flavored e-cigarettes use both natural and synthetic flavorings all of which are FDA approved and are used in food products.

But What About the “Chemicals? Why Are There Reports That E-Cigarettes Have Chemicals that Are Not Safe?

Keep in mind that every ingredient (even natural ingredients) in every product we use and consume has a chemical makeup, so all ingredients are, in fact “chemicals”. The media loves to twist things which is why the very word “chemical” has a negative connotation. 

 …Speaking of Twisting the Truth

E-cigarette testing and reporting has fallen victim to “junk science”.  Junk science is non-scientific data and analysis used to advance special interests and hidden agendas. The media is filled with frightening reports concerning the dangers of nicotine, second-hand vapor and e-cigarette use in general. If you’re looking for reports that negate these claims check out the CASAA website – The Consumer Advocates for Smoke-free Alternatives Association.

Are There Scientific Reports That Say E-Cigarettes Are Safer Than Cigarettes? 

Yes. The true science about e-cigarette safety is emerging, while the old junk science is being exposed and ridiculed for being fraudulent and politically motivated.

The now famous Drexel University Study confirmed that smokeless, tobacco-less, tar-less products are no cause for concern; certainly not a cause for the same concerns that accompany tobacco cigarettes.

The study also concluded that there was absolutely no worry about risks to bystanders from e-cigarette vapor.

nicotine vs caffeine

Nicotine vs Caffeine

Isn’t Nicotine Toxic?

No. Unless you consume huge amounts of nicotine, (and it’s unlikely you would do so), tests now show that nicotine is no more harmful to you than caffeine. An exhaustive study that overturned dubious experiments dating back to the 1850’s, was conducted by Dr. Jacques Le Houezec, Consultant in Public Health, Tobacco Dependence, Amzer Glas, Rennes, France. He concluded:

-Nicotine lethal dose has been overestimated. 
-Long-term use of pure nicotine has not been shown to pose health
problems in animals.
-The health risks from pure nicotine in humans appear to be small if any.
-Pure nicotine use, as with e-cigarettes, seems less addictive than when
smoked in tobacco, and is considerably less harmful.

But Didn’t the FDA Submit a Report That Found Trace Elements of Carcinogens in E-Cigarettes?

Professor Carl Phillips of the TobaccoHarmReduction.org Institute at the University of Alberta, Canada was one of many medical professionals who exposed the now notorious FDA study as being pure junk science. He indicated that if that study was recognized…

“We’d have to ban half the foods that are available. I mean, the FDA study really didn’t find any cancer risk. That study was basically pure propaganda…..there’s no significance of those findings whatsoever from a scientific or health standpoint. From a political standpoint, the fact that they did that was quite significant.”

Virgin Vapor Organic ELiquids

E-cigarettes have become the preferred smoking alternative for millions of smokers and have gained the support of prominent health organizations and scientists worldwide who recognize the product’s tremendous value as an effective way to save millions of lives.

Are e-cigarettes emphatically “safe”? The best answer is to say that it’s too early to tell. Are they “safer” than traditional cigarettes? Scientists and e-cigarette advocates say that they are emphatically safer than tobacco cigarettes and can reduce the harm caused by smoking tobacco.

E-Cigarette Regulations

Greg Conley, the Consumer Advocate for Smoke-Free Alternatives Association, has been quoted as saying that the calls for e-cigarette regulation are a “perverse interpretation of the precautionary principle.”

The precautionary principle holds that until all possible risks are assessed, new technologies shouldn’t be allowed to move forward.

My Two Cents

E-cigarette safety aside, I find it amazing how junk science reports have taken control of our lives; dictating to the public what not to eat and even what not to breathe. To cite E-Cigarette Review site CloudNine’s article on the subject,

“If you’re really worried about ingesting dangerous chemicals, don’t drink beer, wine or water; or eat tuna, sardines or brussels sprouts because they contain toxic amounts of arsenic,.. but that’s not the trending story.”

    Excellent article Hillary, thank you. I have a friend who stopped vaping because of the pseudo-scientific claims, i will point him in the direction of this piece. I already had to convince him popcorn lung from vaping was a complete hoax.

    • Hillary

      Thank you Ross! Much appreciated. We can only hope that the FDA chairman’s recent commitment to review more scientific papers regarding ecig safety will play out.

  • Roger Brulehotte

    And not a single word about Diacetyl, Acetoin and Acetyl Propionyl… Really?!

  • Jerad

    Thank you hillary – we have little on our side as vapers because so much money is being lost. Greedy people run this world and if anything, it’s all about the money…

    • Hillary

      Thanks Jerad. I do remain positive and believe the tides (and our judicial system) will turn to favor vapers who have a right to choose a cigarette alternative that truly satisfies and that is, as Public Health England recently announced, “about 95% safer than cigarettes”.
