A new study published November 17, 2017, by Nature takes a look at the health effects of e-cigarette use in a 3.5 year observational study of nine daily users, and a control group of twelve non smokers, with a median age of 29. All participants had not smoked tobacco previous to their e-cigarette use.
The study measured various health indicators including blood pressure, heart rate, body weight, lung function, respiratory symptoms using state of the art technology over the course of the observation period.
“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.”
On recidivism during the observation period:
“In the present study, over a period of about 4 years, none of the EC users started smoking tobacco cigarettes (two stopped vaping completely) and two never smokers from the reference group (never smokers, not using ECs) started smoking.”
An encouraging study proving out the science behind the harm reduction potential of e-cigarette use, and one of many ongoing long term studies to be released as the outcomes realized by e-cigarette users become studied and corroborated by health professionals.
