New evidence shows vaping can harm lung function in healthy people

There is more evidence that vaping causes abnormal lung function in young, otherwise healthy people.

In a new study, researchers found immediately after vaping, lung function worsened to levels usually seen in people with chronic lung diseases such as chronic obstructive pulmonary disease.

In addition, in people younger than 25 who use e-cigarettes, gas exchange-related metrics of lung function similar to rates typically seen in 60-year-olds.

The research was conducted by a team at the University of California San Diego (UCSD) Health Sciences.

Vaping usually consists of multiple “hits” throughout the day.

Research suggests lung function might not return to normal values between sessions, depending on usage intervals.

Some of the changes caused by repeated vaping may potentially also lead to long-term problems similar to those seen in smoking.

This is particularly worrisome in a younger population, who may be exposed to vaping for many years.

In the study, the team used noninvasive imaging tools to assess lung function in six men and three women—specifically the exchange of fresh air and blood flow to different parts of the lung—which directly impacts the efficiency of gas exchange in the lungs.

The goal is to use the information to debunk misconceptions that vaping is “relatively harmless.”

Researchers also want to make the data available to regulatory agencies and government leaders to develop public health policies and better oversight of vaping products.

One author of the study is Abhilash Kizhakke Puliyakote, PhD.

The study is published in the Journal of Applied Physiology.
