Vapor particles of e-cigs are too small to damage lung surfactant, says new study

A large portion of the general public still seems to be confused about the differences between smoking and vaping.  While both actions involve the exhaling of a white, gaseous substance, the similarities basically stop right there.

The primary, highly significant distinction that often goes unnoticed is that combustible tobacco smoke is laced with carcinogenic levels of tar and other chemicals which are hazardous to the health of the smoker as well as to innocent bystanders.  Vaping, on the other hand, is 100% tobacco- and tar-free, and study after study has already proven that second-hand vapor is essentially non-toxic.  In fact, some research suggests that the vaporized propylene glycol of e-liquids acts as a natural antibacterial for the mouth and lungs.


New research conducted by scientists from Ohio University (OU) supports these previous findings while also further indicating that, unlike smoking, vaping does not produce any measurable damage to the lung surfactant of the human body.  What is lung surfactant?  It’s a filmy substance covering the interior of the lungs that absorbs much of the respiratory surface tension caused by the body’s alveolar fluid.  Without this gooey coating, breathing would be much more laborious – even for the healthiest of individuals.   

The Ohio University vaping study

The findings of the OU vaping study are published in the journal BMC Respiratory ResearchThe paper is entitled, Electronic cigarette vapor alters the lateral structure but not tensiometric properties of calf lung surfactant.  To briefly summarize, the scientists began by exposing the lung surfactant of calf lungs to the first- and second-hand smoke of combustible cigarettes compared to the respective equivalents of e-cig vapor.

The surfactant was removed from the calf lungs and spread across a scientific instrument called a Langmuir trough which is useful for measuring the related surface tensions.  The researchers also experimented with various e-liquids of different flavoring profiles.  Meanwhile, all clinic trials were compared to the same tests using normal, everyday air.

While the OU team does validate findings from several previous research studies indicating that vaping is substantially less harmful than smoking, the scientists are also careful to clarify that those levels will vary depending on the vaping device and e-liquid being vaped.  However, they also make clear that the vapor from e-cigarettes contains no tobacco and no tar, which is the real killer.

Furthermore, the researchers also determined that the vapor particles of electronic cigarettes are simply too small (compared to the smoke particles of combustible tobacco cigarettes) to travel too deeply into the lungs.  Therefore, e-cig vapor cannot possibly adversely affect the lung surfactant.

“E-cigarette vapor regardless of the dose and flavoring of the e-liquid did not affect surfactant interfacial properties. In contrast, smoke from conventional cigarettes had a drastic, dose-dependent effect on Infasurf®interfacial properties reducing the maximum surface pressure from 65.1 ± 0.2 mN/m to 46.1 ± 1.3 mN/m at the highest dose. Cigarette smoke and e-cigarette vapor both altered surfactant microstructure resulting in an increase in the area of lipid multilayers. Studies with individual smoke components revealed that tar was the smoke component most disruptive to surfactant function.”

Not to put too fine a point on the matter, the OU scientists also note that the flavorings of e-liquids also have no adverse effects on the lungs.  Remember, the primary conclusion of this study is that the vapor particles of e-cigs are so small in diameter that it is virtually impossible for them to travel as deeply into the lung cavity as the smoke from conventional cigarettes.

This data is important because many state and city governments are aggressively trying to enact legislation that bans flavored e-liquids.  San Francisco has already done so, and the U.S. Food and Drug Administration (FDA) is currently entertaining the idea of creating additional deeming regulations that will effectively implement a flavor ban at the national level.

Vaping peppermint as a treatment for allergy-induced asthma

While a cure for asthma remains fleeting, scientists now believe that vaping peppermint oil acts as a natural medical therapy to significantly reduce the number and severity of related symptoms.  According to statistics published by the American Lung Association, approximately 26 million people in the United States alone are currently diagnosed with this chronic and potentially life-threatening disease.

Although there are several forms of prescription medications that can help manage the symptoms, they often come with sometimes uncomfortable side effects.  As a result, many asthmatics are now turning to vaping peppermint oil as an effective and less costly alternative.

Patients often claim that an asthma attack feels as if someone is sitting on their chest preventing them from breathing properly.  Symptoms of the less severe cases can range from a slight tightness in the chest to shorter bouts of coughing and wheezing.  The more urgent asthma attacks might cause the patient to be rushed to the emergency room for immediate professional treatment.  The three types of medical asthma include the following.

  • Occupational asthma: Triggered when the patient develops an aversion to specific chemicals and substances found in the workplace.
  • Exercise-induced asthma: Triggered by various forms of strenuous activities, such as climbing stairs, running, or heavy lifting.
  • Allergy-induced asthma: Triggers when patients are genetically predisposed to allergies related to dust, dander, or other common substances.

It is this third form of the disease – allergy-induced asthma – where medical professionals believe vaping peppermint oil can prove most beneficial.  The peppermint plant is one of Mother Nature’s antihistamines.  And because this plant is found in nature, the human body absorbs its medicinal qualities much faster and more efficiently than most Big Pharma medications ever could. 

Vaping peppermint for asthma and other medical purposes

According to the Global Health Center in Houston, Texas, mentha piperita or peppermint also acts as a natural antibacterial preventing the development of bacteria in both the lungs and the oral cavity in much the same way as the vaporized propylene glycol found in e-liquids. This bacteria-killing effect is also one of the primary reasons that so many toothpastes and mouthwashes are flavored with peppermint.  Other medicinal benefits of peppermint include:

  • Useful therapy for Irritable Bowel Syndrome (IBS)
  • Aids in digestive issues
  • Relieves nausea and stomachaches
  • Reduces chemotherapy-induced nausea and vomiting
  • Inhibits pregnancy-related morning sickness
  • Sometimes cures hiccups
  • Reduces sinus inflammation
  • Prevents snoring
  • Reduces the severity and frequency of menstrual cramps
  • Manages depression and anxiety
  • Reduces symptoms related to arthritis and joint issues
  • Useful remedy for muscle spasms
  • Heals rashes and irritations of the skin
  • And so much more

If vaping peppermint oil is not preferable, its medicinal benefits can sometimes be achieved by simply rubbing a peppermint-infused balm on the affected area of the body.  For example, for relief from nausea or stomach aches, rubbing a bit of peppermint oil on the belly often works wonders.
