Study examines the health impact of e-cigarettes over 3.5 years in regular daily users

A recent study, published in Nature Scientific Reports, examined the health impact of e-cigarettes over 3.5 years in regular daily users.

The study reports that blood pressure, heart rate, body weight, lung function, respiratory symptoms, exhaled breath nitric oxide, exhaled carbon monoxide, and high-resolution computed tomography of the lungs were measured for a cohort of daily e-cigarette users, and compared to a reference group of never smokers.

No significant changes could be detected over the 3.5 year observation period between the e-cigarette users and the control subjects in any of the health outcomes investigated. No pathological findings could be identified on high-resolution computed tomography of the lungs and no respiratory symptoms were consistently reported in the e-cigarette users group.

The study is available to view as an open article on nature.com.
