A multiyear vaping study conducted in 2017 may have shed new light on the e-cig health debate. In an interesting break from the norm, real world testing scenarios were used with subjects using their own vape devices and liquids.
The three-and-a-half year study examined the long-term health effects of vaping, and involved never smokers and non-users. Significant changes in participant health were observed and recorded, including: blood pressure, heart rate, body weight, lung function, respiratory symptoms, as well as exhaled bio-markers of airway inflammation. This was the first study to explore the “health effects of prolonged exposure to EC (electronic cigarette) use in never smokers.” And its findings are completely contrary to the common beliefs of today.
Adults ages >=18 years of age were identified amongst a pool of regular vape shop visitors. Shop owners were instructed to ask regular clients a series of questions about smoking history and EC (Electronic Cigarette) use. Visitors who had never smoked, or smoked less than 100 cigarettes in their lifetime were all considered for the study. Other criteria for test subjects were as follows:
- >= 3 months of EC use.
- Free medical check up on completion.
Age and sex matched non-smokers were selected from the hospital staff as a control. Subjects involved in the study were recruited from June 2013 to September 2013, with data collection completed on March of 2017.

Upon the completion, multiple health markers were examined, and multiple data-sets had were viewed. What the study found was groundbreaking and completely contradictory to common belief. Yet the 3.5 year study on the health impact of E-cigs had been conveniently skimmed over by the mainstream media and anti-E-cig communities.
Even though the period of examination was short (figuratively speaking), and the testing pool was relatively small (When compared to others…), the study successfully achieved what it had set out to observe. It showed that zero EC users had started smoking tobacco cigarettes (with two having stopped vaping completely), two never smokers in the control group (not using ECs) had started smoking.
The study also found no decreases in the following:
- Spirometric indices
- Development of respiratory symptoms
- Changes in markers of lung inflammation in exhaled air
- Early lung damage on HRCT
- Blood pressure
- Heart rate
Even the heaviest EC users in the study never exhibited any signs of emerging lung injuries. In some cases, even with users vaping the highest levels of nicotine, subjects showed no changes in FeNO or eCO when compared to control.
It should be noted that although the findings were 100% accurate, the tests completed and self-reporting data collected may not have been sensitive enough to detect early changes in chronic inhalation of EC aerosols. Similar to most studies, the findings should be used in unison with other similar pieces in an effort to compose a solid base for comparing possible health benefits and complications.

TI – Health impact of E-cigarettes: a prospective 3.5-year study of regular daily users who have never smoked, JO – Scientific Reports, SP – 13825, VL – 7 , IS – 1. AB – Although electronic cigarettes (ECs) are a much less harmful alternative to tobacco cigarettes, there is concern as to whether long-term ECs use may cause risks to human health. We report health outcomes (blood pressure, heart rate, body weight, lung function, respiratory symptoms, exhaled breath nitric oxide [eNO], exhaled carbon monoxide [eCO], and high-resolution computed tomography [HRCT] of the lungs) from a prospective 3.5-year observational study of a cohort of nine daily EC users (mean age 29.7 (±6.1) years) who have never smoked and a reference group of twelve never smokers. No significant changes could be detected over the observation period from baseline in the EC users or between EC users and control subjects in any of the health outcomes investigated. Moreover, no pathological findings could be identified on HRCT of the lungs and no respiratory symptoms were consistently reported in the EC user group. Although it cannot be excluded that some harm may occur at later stages, this study did not demonstrate any health concerns associated with long-term use of EC in relatively young users who did not also smoke tobacco.
