Vaping has become a popular alternative to traditional tobacco smoking in recent years. However, concerns about the health risks associated with vaping have also emerged. One of the main concerns is whether vaping can increase the risk of developing cancer. In this article, we will examine the available evidence on this topic to determine whether there is a link between vaping and cancer.
Key Takeaways:
- E-cigarettes, also known as electronic nicotine delivery systems (ENDS), are battery-operated devices that heat a liquid, known as e-liquid or e-juice, to produce an aerosol that is inhaled by the user.
- The e-cigarette aerosol may contain potentially harmful substances such as nicotine, volatile organic compounds (VOCs), flavoring chemicals, diacetyl, and formaldehyde.
- The available evidence suggests that there is a potential link between vaping and an increased risk of developing cancer, but more research is needed to fully understand the long-term effects of vaping on cancer risk in humans.
- It is advisable for individuals to exercise caution and consider the potential risks associated with vaping.

Understanding Vaping and How It Works
Firstly, it is important to understand what vaping is and how it works. E-cigarettes, also known as electronic nicotine delivery systems (ENDS), are battery-operated devices that heat a liquid, known as e-liquid or e-juice, to produce an aerosol that is inhaled by the user. The e-liquid can contain nicotine, as well as other substances such as flavorings and chemicals.
When the e-cigarette device is turned on, the battery heats a coil that vaporizes the e-liquid. The aerosol produced is then inhaled through a mouthpiece on the device. Although e-cigarettes do not produce tobacco smoke, the aerosol still contains potentially harmful substances that can cause various health effects.
E-cigarettes come in a variety of sizes and shapes, including cigarettes, cigars, and pipes. Some e-cigarettes are disposable, while others are rechargeable and use replaceable cartridges or pods that contain the e-liquid. Some devices also feature customizable settings that allow users to adjust the temperature, flavor, and strength of the aerosol produced.
Overall, vaping has become a popular alternative to traditional tobacco smoking, but it is important to understand the potential health risks associated with these electronic nicotine delivery systems.
Health Effects of E-Cigarette Aerosol
Several studies have focused on the composition of e-cigarette aerosol and its potential health effects. The aerosol produced by e-cigarettes is not harmless, as some may believe. It contains nicotine, which is an addictive substance found in traditional tobacco products. Nicotine can harm the brain development of teenagers and can also have adverse effects during pregnancy, such as premature birth and low birth weight.
In addition to nicotine, e-cigarette aerosol may contain other potentially harmful substances. These include volatile organic compounds (VOCs), which can cause irritation and damage to the respiratory system, as well as flavoring chemicals that may contain diacetyl, a compound linked to a serious lung disease called bronchiolitis obliterans. Formaldehyde, a known carcinogen, can also be produced when e-liquids overheat.
Potential Harmful Substances in E-Cigarette Aerosol
In addition to nicotine, e-cigarette aerosol may contain other potentially harmful substances. These include volatile organic compounds (VOCs), flavoring chemicals, diacetyl, and formaldehyde.
VOCs are chemicals that can cause irritation and damage to the respiratory system. Some VOCs commonly found in e-cigarette aerosol include benzene, toluene, and styrene. These chemicals are known to cause cancer and other serious health problems.
Flavoring chemicals used in e-cigarettes may contain diacetyl, a compound linked to a serious lung disease called bronchiolitis obliterans. This disease, sometimes referred to as “popcorn lung,” can cause coughing, wheezing, and shortness of breath. While many e-cigarette manufacturers have stopped using diacetyl as a flavoring agent, other harmful compounds may still be present.
Finally, formaldehyde is a well-known carcinogen that can be produced when e-liquids are heated to high temperatures, as may happen when a vape device is used at a high setting. Inhaling formaldehyde can increase the risk of developing cancer.
It is important to note that the exact composition of e-cigarette aerosol can vary widely depending on the specific device and e-liquid used. Some devices may produce more harmful substances than others, and e-liquids can contain different amounts of nicotine and other chemicals. It is important for individuals who choose to use e-cigarettes to be aware of the potential risks and to use these products with caution.
Comparing E-Cigarettes to Traditional Cigarettes
The Royal College of Physicians has stated that e-cigarettes are likely to be significantly less harmful than traditional cigarettes. This conclusion was reached after a thorough review of the available scientific evidence. E-cigarettes do not produce tar, which is a major contributor to the harmful effects of smoking traditional cigarettes. Furthermore, e-cigarettes do not contain the many harmful chemicals that are found in tobacco smoke, such as carbon monoxide, ammonia, and benzene.
However, it is important to note that e-cigarettes are not completely harmless. They still contain nicotine, which is an addictive substance and can have adverse effects on brain development in teenagers and on pregnancy outcomes. E-cigarette aerosol can also contain other potentially harmful substances, as discussed earlier in this article. Additionally, the long-term health effects of vaping are not yet fully understood, and further research is needed to determine whether there are any significant risks associated with long-term use.
Can You Get Cancer From Vaping?
In terms of the specific link between vaping and cancer, there is limited evidence available. A report commissioned by the Office for Health Improvement and Disparities in England found that nicotine vaping, while not risk-free, presents a small fraction of the risk of smoking combustible tobacco. However, this report did not specifically address the risk of cancer associated with vaping.
One study published in the Journal of Cancer Biology examined the biochemical and biological effects of nicotine and e-cigarette aerosol in human cells and mice. The researchers found that nicotine and a specific nitrosamine called NNK, which can be formed from nicotine under certain conditions, caused DNA damage and inhibited DNA repair mechanisms in human lung and bladder cells. They also found that e-cigarette aerosol induced the same type of DNA damage in lung, heart, and bladder tissues of mice. Furthermore, when mice were exposed to e-cigarette aerosol for an extended period of time, a significant number developed lung cancer and bladder pre-cancerous changes.
While these findings suggest a potential link between nicotine, nitrosamines, and cancer, they are based on laboratory and animal studies, and further research is needed to determine the extent of the risk in humans. It is important to note that the development of cancer typically takes many years, and e-cigarettes have only been widely used for around a decade. It may take a significant amount of time before any potential long-term effects on cancer risk become apparent.
In conclusion, the available evidence suggests that there is a potential link between vaping and an increased risk of developing cancer. Nicotine, the main addictive substance in e-cigarettes, can be transformed into carcinogenic nitrosamines under certain conditions. Laboratory and animal studies have shown that these nitrosamines can cause DNA damage and promote the development of cancerous changes in cells and tissues. However, more research is needed to fully understand the long-term effects of vaping on cancer risk in humans. In the meantime, it is advisable for individuals to exercise caution and consider the potential risks associated with vaping.
