Does Vaping Raise Lung Cancer Risk?

Vaping is a common alternative to smoking cigarettes. Nevertheless, it does not come without risks.

E-cigarettes and other vaping products contain nicotine, flavorings, propylene glycol, glycerin, and other chemicals. Many of these substances may be toxic to the lungs and are thought to raise lung cancer risk.

Smokeless Tobacco

Smokeless tobacco (also called chewing, dipping, oral, spit, or snuff) is nicotine-containing tobacco that is not burned or inhaled. It comes in many shapes, such as sticks, plugs, bricks, and leaves. The tobacco is usually placed between the cheek and lower lip, then spit or swallowed.

The nicotine in smokeless tobacco is more potent than cigarettes and stays in your blood longer. It makes it harder to stop using.

It can also raise lung cancer risk, especially in heavy smokers. The tobacco-specific nitrosamines, or TSNAs, are the most dangerous compounds in smokeless tobacco.

They are also dangerous to pregnant women, who can have a stillbirth, low birth weight, and heart problems in their babies. They can also poison children and pets.

These products are often marketed as a way to quit smoking, but they do not work and may even be more harmful than cigarettes. They also have many toxic chemicals as cigarettes, including three times as much nicotine.

These products can be addictive and can damage the parts of the brain that control attention, learning, and mood. They can also lead to addiction to other drugs. They can also cause other health problems, including respiratory infections, mouth ulcers, gum disease, and tooth loss. They can also raise the risk of heart disease and cancer.


E-cigarettes heat a liquid solution to produce an aerosol that can be inhaled. Typically, e-cigarette solutions contain nicotine, flavoring, and a humectant, like propylene glycol, to hold moisture and create an aerosol.

The issue is that does vaping cause lung cancer while e-cigarettes are not a safe cigarette substitute. They include substances that might irritate the lungs and lead to lung conditions.

These toxins include formaldehyde, acetaldehyde, acrolein, and diacetyl. These chemicals are all carcinogens and can increase the risk of cancer.

Additionally, e-cigarettes contain high levels of toxic heavy metals that can cause serious health problems. Among the metals, chromium, nickel, and manganese are particularly harmful.

Using e-cigarettes can lead to a severe lung condition called e-cigarette or vaping product use-associated lung injury (EVALI). This condition causes cough, wheezing, and other respiratory symptoms. It can lead to hospitalization and other medical complications.


Nicotine is the primary psychoactive ingredient in cigarettes, electronic cigarettes, and other tobacco products. It speeds up the messages that travel from your brain to your body. It is also a powerful stimulant that can cause feelings of excitement, anxiety, and depression.

It can be addictive and difficult to quit, and it causes many serious health problems, such as heart disease, stroke, and Type-2 diabetes. It can also damage the lungs and increase your risk of developing cancer.

According to the American Cancer Society, the lungs are susceptible to nicotine. The toxins in smoke can make the cells in the lungs react to the smoke and change their DNA.

It can then lead to a series of changes in the cell that eventually cause lung cancer. It is also possible that nicotine could exacerbate existing conditions such as asthma and chronic obstructive pulmonary disease (COPD) by irritating the lungs.

Another hazard associated with smoking is air blisters, which develop at the top of the lungs and can rupture without producing any symptoms. When these blisters burst, they create a hole that allows oxygen to escape the body. This condition is called primary spontaneous pneumothorax or “popcorn lung.” Oxygen treatment and rest can help these lungs heal.

The e-liquids in vaping products contain nicotine and other toxic chemicals that can harm your lungs, and research shows that they may raise lung cancer risk. If you decide to use e-cigarettes, you must be aware of the hazards and seek medical counsel because the FDA has not yet decided whether they are safe.

Ethyl Maltol

Ethyl maltol (C7H8O3) is a flavoring chemical that gives foods and beverages a flavor of sweet, caramel, or cotton candy. It enhances the taste of various food products, including cakes and slices of bread, chocolates, beverages, ice creams, pickled vegetables, and some meat products.

This chemical has been shown to increase lung cancer risk when exposed to cigarette smoke or vaping liquid. It has been linked to an inflammatory response, and the generation of free radicals, which research suggests can lead to the formation of cancerous cells.

In a study on e-cigarettes, ethyl maltol inhibited the innate immune response in a laboratory setting by suppressing lung epithelial cell function and increasing the amount of oxidative stress. Additionally, this chemical decreased the number of phagocytic cells, which is essential for clearing pathogens and keeping them from entering the body.

This chemical was also found to cause cytotoxicity in two different lung epithelial cell lines. Its toxicity was enhanced when co-exposed with copper (Cu) or iron (Fe). EM may facilitate the transport of heavy metals across the plasma membrane.

Propylene Glycol

Propylene glycol is a common additive in cosmetics and personal care products. It has been used as a humectant, skin-conditioning agent, viscosity-decreasing agent, and solvent.

Propylene glycol is generally safe for humans. However, it can cause mild side effects, including redness and skin irritation. These symptoms usually subside after the body has had time to break down the chemical.

In addition, people with asthma or other respiratory problems should avoid using vaping products that contain this ingredient. They might end up exacerbating their situation.

It is because propylene glycol can be absorbed into the bloodstream and allowed to enter the lung. It can cause enlarged cells to form in the airways. It can also increase the number of other chemicals entering the lungs, making them even more dangerous.

Moreover, high doses of propylene glycol in medications can be toxic for young children and infants. It is because their bodies cannot process it as effectively as adults.

Another reason why people with heart disease or other health conditions should avoid using propylene glycol is because it can lower the body’s blood pressure and heart rhythm. These symptoms can lead to heart attacks and other serious medical issues.

It is why it is essential to understand the facts surrounding propylene glycol. While it is not harmful to the general public, it can be a significant problem for people with asthma or other respiratory conditions.


When it comes to food, flavorings can immensely impact our gustatory experience. They can make reduced-fat foods taste rich and creamy, add salty zest to low-sodium products, or create perfectly healthy alternatives that meet our taste preferences without compromising on the nutritional quality of the product.

However, the ingredients that are used to create these flavors can be harmful to your health if they are exposed to air for prolonged periods. For example, ethyl maltol, a common ingredient in caramel-flavored e-liquids, has been linked to inflammatory response and free radical production.

It also can increase the risk of lung cancer. The chemical diacetyl, present in some flavors, can cause bronchiolitis obliterans, an irreversible condition that results in scarring of the tiny airways in your lungs.

These blisters develop on a small portion of your lungs, called the bronchus, and usually do not produce symptoms until they rupture. Nevertheless, they can lead to severe problems, including collapsed lungs, which require oxygen treatment and possibly surgery to repair.

Research shows that flavored e-liquids can alter pro-inflammatory biomarkers, cytokine release, and oxidative stress in pulmonary epithelial, fibroblast, basal, and alveolar cells. Cinnacide and black licorice (an active flavoring ingredient) increased alveolar macrophage phagocytosis, while vanilla reduced MUC5AC expression in BAL. These EC-mediated toxicity effects are similar to those of tobacco.
