Health risks of vaping

Vaping has become increasingly common, particularly among young adults who often view it as a safer alternative to traditional cigarette smoking.

Electronic cigarettes, commonly known as vapes, work by heating a liquid that contains nicotine, flavourings and other chemicals into an aerosol that is inhaled into the lungs.

While vaping may expose users to fewer toxic substances than conventional cigarettes, health experts warn that it is not risk-free.

How vaping affects the lungs

One of the first organs affected by vaping is the respiratory system.

The aerosol produced by e-cigarettes contains tiny particles that can irritate lung tissues and airways. Over time, this irritation may lead to coughing, wheezing and shortness of breath.

According to the World Health Organization (WHO), e-cigarette emissions typically contain nicotine and other toxic substances that can be harmful to both users and non-users exposed to the aerosol.

The organisation notes that the long-term effects are still being studied, but existing evidence points to potential risks to lung health.

“E-cigarettes are harmful to health and are not safe,” the World Health Organization noted.

Impact on heart health

Nicotine, a common ingredient in many vaping products, can have significant effects on the cardiovascular system.

It increases heart rate and blood pressure by stimulating the release of adrenaline.

Research published by health authorities, including the Centres for Disease Control and Prevention (CDC) suggests that nicotine exposure can place additional strain on the heart and blood vessels.

Frequent use may increase the risk of cardiovascular complications, especially among individuals who already have underlying heart conditions.

Effects on the brain

The brain is particularly vulnerable to nicotine exposure. Nicotine affects areas responsible for attention, learning and mood regulation.

Health experts caution that repeated exposure can lead to dependence, making it difficult for users to stop vaping.

Nicotine can alter brain development in adolescents and young adults, whose brains continue developing into their mid-twenties. This may affect memory, concentration, and impulse control.

The risk of addiction

Many people begin vaping believing it is harmless, only to develop a dependence on nicotine. Addiction can occur gradually, with users experiencing cravings and withdrawal symptoms when they attempt to quit.

Nicotine addiction can lead some individuals to increase their usage over time, exposing them to higher levels of potentially harmful substances contained in vape liquids.

 Effects on oral health

Vaping may also affect the mouth and teeth. Dental professionals have linked vaping to dry mouth, gum irritation and an increased risk of oral inflammation.

Reduced saliva production can create an environment where bacteria thrive, potentially contributing to tooth decay and bad breath.

Some studies have also raised concerns about the impact of flavouring chemicals on oral tissues, although more research is ongoing.

Additional effect

The aerosol released during vaping is not simply harmless water vapour. It may contain nicotine, ultrafine particles and chemical compounds that can be inhaled by people nearby.

The WHO advises that exposure to second-hand aerosol may pose health risks, particularly for children, pregnant women and individuals with respiratory conditions.

Although vaping is often marketed as a modern alternative to smoking, health experts continue to caution that it carries its own set of health risks. From lung irritation and nicotine addiction to potential effects on the heart and brain, the evidence suggests that vaping is far from harmless.

Public health authorities recommend that non-smokers avoid vaping altogether and that users seeking to quit nicotine products consult healthcare professionals for support and guidance.
