E-cigarettes declared not harmful to pulmonary health?

A study by a University of Ohio research team could change the public opinion on e-cigarettes. The research tends towards the conclusion that the vapour emitted by e-cigs is not harmful to pulmanory health. The reason for this is that the particles are so small that they cannot damage pulmonary cavities.

Published by BMC Respiratory Research, the study focused on the structural changes that e-cig vapour could cause. To do this, the research team exposed veal lungs to vapour produced by a range of different electronic cigarette devices. No damages were observed, whatever the nicotine strength or flavouring.

Pulmonary surfactant that lines the lung interior was however seriously damaged by cigarette smoke. The blend of tar, tobacco and nicotine contained in smoke is extremely harmful to health. The study proces that this is not the case with e-cigs.

Studies that validate the switch to vaping

These results represent a major leap in our understanding of vaping and its effects on health.  The University of Ohio team affirm that e-cig vapour is harmless to lung health. This was verified across all e-juices tested at various dosages throughout the study.

The fact that e-cig vapour particles are so small prevents them from deeply penetrating tissue. This means that they do not contaminate pulmonary surfactant, and do not become encrusted in the lung cavity. E-cigs vapour does not contain tar, which is the leading cancer-causing agent in classic cigarettes.

What will be the ramifications of this study? Will the FDA, who are considering a ban on certain e-cig juices, re-evaluate their decision? A number of American cities, including San Francisco, have already adopted restrictive legislation for flavoured e-liquids.  This study proves that e-cigs represent more than ever an effective and safe substitute to traditional cigarettes.
