E-cigarettes have gained popularity in recent years as an alternative to traditional tobacco smoking. Designed to deliver nicotine without the harmful tar present in combustible cigarettes, they have been marketed as safer options. However, what do e cigarettes do to your lungs over time?
When inhaled, the vapor from e-cigarettes enters the lungs and the nicotine, along with other chemicals in the vapor, gets absorbed into the bloodstream. Despite being touted as a healthier option, research is ongoing to fully understand their impact on lung health.

Chemical Composition of E-cigarette Vapor

It’s crucial to note that even though e-cigarette vapor lacks tar, it contains several potentially harmful substances. Propylene glycol and vegetable glycerin form the primary base liquids, which can irritate respiratory tissues upon prolonged exposure. Flavoring agents and other additives can decompose into harmful compounds when vaporized at high temperatures.

Inflammation and Cellular Damage

One of the most concerning aspects is the potential for e-cigarettes to cause inflammation. Studies have shown that exposure may increase oxidative stress levels, resulting in cellular damage within the lungs. This oxidative stress can lead to chronic inflammation, a precursor to serious conditions like COPD.

Long-term Consequences

The long-term effects of e-cigarettes on lung health are still not fully understood. While some users may experience fewer respiratory symptoms compared to tobacco smokers, others may develop conditions that resemble the early stages of lung diseases.

Impact on Lung Function

Research indicates that regular use of e-cigarettes can lead to altered lung function. Even among young, healthy individuals, vaping has been linked to reduced lung capacity and lower lung volume. Such changes can diminish overall respiratory health and stamina.
