Research & Commentary: Study Finds 'No Detectable Changes in Lung Health' of E-Cigarette Users Who Have Never … – The Heartland Institute

In a first-of-its-kind analysis, researchers found “no detectable changes in lung health in never smokers who have been regularly vaping for at least four years,” according to a November study published in Scientific Reports. To date, this is the first long-term study analyzing electronic nicotine delivery system (ENDS) users.

In the observational study, researchers compared nine daily ENDS users that had never smoked tobacco to a “reference group of twelve never smokers.” Researchers compared health outcomes of the two groups, including “blood pressure, heart rate, body weight, lung function, respiratory symptoms, exhaled nitric oxide, exhaled carbon monoxide, and a high-resolution computed tomography of the lungs.” The researchers say their findings show “no significant changes in any of the health outcomes investigated, including measures of lung function and lung inflammation.”

The authors also observed the potential effects of nicotine and diacetyl and determined they had created no long-term negative effects.

There has been a growing concern of the “adverse cardiovascular effects” of nicotine and the use of ENDS products. Some researchers have been particularly concerned about their potential effect on blood pressure and heart rate. The Scientific Report study found no significant changes in blood pressure or heart rate among e-cigarette users. Researchers also found higher concentrations of diacetyl did not lead to the development of “bronchiolitis obliterans,” commonly called “popcorn lung.”

This is the latest, but not only, study showing evidence ENDS can be used effectively and safely as a tobacco harm reduction tool. In 2015, Public Health England found e-cigarettes to be “around 95% safer than smoking.” The Tobacco Advisory Group of the Royal College of Physicians concluded in 2016 e-cigarette use is “unlikely to exceed 5% of the harm from smoking tobacco.” Similarly, NHS Health Scotland issued a joint statement in September 2017 in which the agency said
