Vaping is often marketed as a safer alternative to smoking, but its effects on lung health are still a topic of concern. This article explores how vaping impacts the lungs, highlighting both the potential risks and its differences from traditional smoking.

1. How Vaping Affects Lung Function

Inhaling vapour introduces chemicals like propylene glycol, vegetable glycerin, flavourings, and nicotine into the lungs. While these substances are less harmful than the tar and toxins in cigarette smoke, they can still irritate the respiratory system.

Regular vaping may cause mild inflammation in the lungs, leading to symptoms such as coughing, throat irritation, and shortness of breath, particularly in heavy users.

2. Risks of Vaping for Lung Health

Research has identified several potential risks associated with vaping, including:

• Lung Irritation: Vapour can irritate the airways, especially in individuals with pre-existing conditions like asthma.

• EVALI: E-cigarette or vaping product use-associated lung injury (EVALI) is a serious condition linked to certain vaping products, particularly those containing THC or vitamin E acetate.

• Chronic Bronchitis: Prolonged exposure to vaping aerosols may increase the risk of chronic bronchitis or other respiratory issues.

3. Is Vaping Less Harmful Than Smoking?

Compared to smoking, vaping eliminates harmful combustion products like tar and carbon monoxide. This reduction in toxins means that vaping is generally less damaging to lung tissue than smoking. However, it is not risk-free, and long-term studies are needed to fully understand its effects.

4. Vaping and Exercise Performance

Some vapers report decreased exercise performance, likely due to reduced lung efficiency. This is particularly relevant for those who engage in high-intensity physical activities or sports. Quitting vaping can help improve lung capacity and endurance over time.

5. Protecting Your Lung Health

If you choose to vape, consider the following tips to minimise its impact on your lungs:

• Avoid using high-powered devices that produce dense vapour.

• Choose e-liquids with minimal additives and avoid questionable brands.

• Take breaks between vaping sessions to reduce exposure.

• Seek medical advice if you experience persistent respiratory symptoms.

Conclusion

Vaping has a less severe impact on lung health than smoking, but it is not without risks. Understanding how vaping affects the lungs can help you make informed decisions about its use. For those concerned about long-term respiratory health, quitting vaping altogether remains the best option.
