What is in Vapes: A Deep Dive into Ingredients

The impact of e-cigarettes on health has become a hotly debated topic as vaping gains popularity among various age groups. Proponents argue that e-cigarettes are a safer alternative to traditional smoking, devoid of the harmful tar and carcinogens. However, critics point out that this narrative oversimplifies the matter. From affecting lung health to posing cardiovascular risks, vaping is far from harmless. This complexity extends to specific populations, such as teenagers, who face unique risks, and even to those exposed to second-hand vapor. In this section, we’ll delve into the multifaceted health implications of e-cigarettes, examining their effects on the lungs, teeth, heart, teenagers, and the risks associated with second-hand exposure.

What Is A Vape?

A vape device, commonly known as an e-cigarette, vape pen, or vaporizer, is a specialized piece of technology designed to convert e-liquid, concentrates, or dry herbs into a vapor that can be inhaled. At its core, a vape device operates on the principles of electrical heating, turning the chosen material into a vapor without initiating combustion. By eliminating the combustion process, which is responsible for creating tar and other carcinogens, vaping is often considered a less harmful alternative to traditional smoking methods.

The anatomy of a vape device generally includes several key components: a battery for power, a tank or cartridge to store the e-liquid or concentrate, an atomizer which contains the coil for heating, and a mouthpiece for inhalation. These parts work in tandem to heat the material to a specific temperature that produces vapor but avoids burning, thus reducing the creation of harmful byproducts.

What adds complexity and versatility to vape devices are the advanced features they now offer. Modern iterations come with customizable settings, including temperature control, variable voltage and wattage, adjustable airflow, and even smartphone compatibility for monitoring and adjustments. Some high-end devices also feature OLED screens that display battery life, resistance, wattage, and even puff count.

Furthermore, vape devices are highly modular, meaning you can mix and match parts from different manufacturers to create a personalized vaping experience. They range from simple, beginner-friendly pod systems to more intricate mods tailored for experienced vapers.

What is in Vapes?

Propylene Glycol and Vegetable Glycerin

These two compounds are the foundational elements of most e-liquids and serve unique but complementary functions. Propylene Glycol (PG) is a colorless, odorless liquid that has the quality of mimicking a traditional cigarette’s throat hit. It’s thinner than VG, which makes it more effective in carrying flavors. However, PG can sometimes lead to dry mouth or throat irritation for certain individuals. On the other hand, Vegetable Glycerin (VG) is thicker and is chiefly responsible for the dense, visually appealing vapor clouds that many vapers love. VG tends to have a sweeter taste, which can slightly influence the flavor profile of your e-liquid. Both PG and VG have been deemed generally safe for oral and topical use by various health organizations, although long-term effects of inhalation are still a subject of ongoing research. Therefore, knowing the PG/VG ratio in your e-liquid can significantly affect your vaping experience, from flavor richness to vapor thickness.


Flavorings are truly the soul of the vaping experience, offering an extensive palette ranging from fruity bursts to decadent desserts. The majority of e-liquids use food-grade flavorings, identical to those found in everyday food items from your local grocery store. These flavorings are generally considered safe for consumption; however, it’s important to note that their safety profiles have primarily been established for ingestion, not inhalation. As the vaping industry continues to evolve, ongoing scientific research is scrutinizing the effects of heating and inhaling these food-grade flavors. Preliminary studies have shown potential health concerns, making it crucial for vapers to stay informed and exercise caution.


Nicotine serves as the addictive catalyst in e-liquids, mirroring its role in traditional tobacco products. It’s often the reason many smokers transition to vaping as a less harmful alternative. Unlike traditional cigarettes, vapes offer a level of customization in nicotine concentration, providing users the option to gradually lower their intake. This flexibility has been hailed as a potential stepping stone for smokers interested in quitting. However, it’s important to note that while vaping is generally considered less harmful than smoking, nicotine itself still presents health risks, including dependency and potential cardiovascular impacts.


Vaping products containing cannabinoids such as THC and CBD have carved out their own niche in the market. Originating from the cannabis plant, these compounds offer distinct experiences: THC is psychoactive and responsible for the “high,” while CBD is non-psychoactive and often used for its potential therapeutic benefits. Both come with their own set of health considerations and legal implications. For instance, THC remains federally illegal in some places, while CBD’s legal status can vary. Understanding the laws surrounding cannabinoid use in your jurisdiction is crucial, as is knowing the potential health impacts of vaping these substances.

Additional Additives

In the quest for a unique vaping experience or longer shelf life, some e-liquid manufacturers incorporate additional additives such as sweeteners, colorings, and preservatives into their formulations. These additives may enhance flavor profiles or improve product longevity, but they’re not without scrutiny. Even though they are usually present in minimal quantities, their long-term effects when inhaled are not yet fully understood. As a conscientious consumer, it’s crucial to thoroughly read the ingredient list and conduct your own research. Some additives have come under fire for potential health risks, making it all the more essential to be an informed buyer.

Vapes Can Also be Addictive

The issue of addiction is a significant concern when discussing both traditional cigarettes and electronic cigarettes (e-cigarettes). Both forms of smoking deliver nicotine, a highly addictive substance, to the user. Here’s why e-cigarettes can be just as addictive as their traditional counterparts:Nicotine Content: Both traditional cigarettes and e-cigarettes contain nicotine, which is known for its addictive properties. In some cases, e-cigarettes can even provide a higher concentration of nicotine than traditional ones.
Ease of Use: The convenience and discreet nature of e-cigarettes can inadvertently lead to more frequent use, potentially resulting in a faster onset of addiction.
Customizable Nicotine Levels: While the ability to adjust nicotine levels could be seen as a benefit, it also allows users to maintain their addiction more easily, even using it as a crutch to avoid withdrawal symptoms.
Social Factors: The trendy and modern image of vaping, especially among younger populations, can make it socially acceptable and thus easier for users to get addicted without the same societal scrutiny faced by traditional smokers.
Psychological Aspects: Many people find the hand-to-mouth action of smoking to be a part of the addictive process. E-cigarettes replicate this experience, contributing to their addictive potential.
Lack of Regulation: The e-cigarette industry is still not as tightly regulated as traditional tobacco products in many areas, which means that consumers might not be fully aware of the nicotine content in the vaping products they are using.
Ignorance or Misinformation: Many people believe e-cigarettes are a safer alternative and may not recognize or admit the addictive risks associated with their use, leading to unintentional addiction.

Benefits of Vapes

The benefits of electronic cigarettes, commonly known as e-cigarettes or vapes, have been the subject of considerable debate among public health experts, smokers, and non-smokers alike. However, many users and some healthcare professionals believe that e-cigarettes offer several advantages compared to traditional tobacco cigarettes. Here are some of the purported benefits.

  1. Reduced Harmful Chemicals: Traditional cigarettes release over 7,000 chemicals when burned, hundreds of which are toxic and around 60 are known carcinogens. E-cigarettes are believed to contain fewer harmful substances as they do not involve combustion.
  2. Less Odor and Residue: Unlike tobacco cigarettes, e-cigarettes do not produce tar or leave a lingering smell on clothing, in homes, or in cars.
  3. Convenience and Discreet Use: Many e-cigarettes are designed to be portable and convenient, allowing for more discreet use—some even resemble everyday objects like USB drives.
  4. Cost-Effectiveness: Although the initial investment in a vaping device can be higher, e-liquids or pods tend to be less expensive over time compared to the recurrent cost of buying cigarette packs.
  5. Wide Range of Flavors: One of the appealing aspects for many users is the wide array of flavors available, from traditional tobacco to fruit, menthol, and even dessert flavors.
  6. Control Over Nicotine Intake: E-cigarettes allow users to choose e-liquids with varying levels of nicotine, or even none at all, giving them more control over their nicotine consumption.
  7. May Aid in Smoking Cessation: Some smokers have successfully used e-cigarettes as a smoking cessation tool, although research in this area is still ongoing.
  8. No Secondhand Smoke: E-cigarettes produce a vapor that dissipates more quickly and is less harmful than secondhand smoke, reducing the risk to bystanders.

The Impact of Vapes on Health

To the Lungs: E-cigarettes don’t produce tar and many harmful carcinogens that traditional cigarettes do, which is a positive aspect. However, vaping is not without respiratory risks. E-liquids can contain harmful substances like diacetyl, which is associated with a condition known as ‘popcorn lung.’ Additionally, some people have reported cases of vaping-associated lung injury (VALI), characterized by symptoms similar to pneumonia.

To the Teeth: Oral health can also be affected by vaping. The propylene glycol found in many e-liquids can lead to dry mouth, which increases the risk of cavities and gum disease. The flavors used in e-liquids can also contribute to tooth decay.

To the Heart: Nicotine, a key ingredient in most e-liquids, has cardiovascular effects. It can increase heart rate and blood pressure, putting strain on the heart and potentially increasing the risk of heart-related issues over time.

To Teenagers: The impact of e-cigarettes on teenagers is particularly concerning. Nicotine exposure during adolescence can affect brain development, particularly in areas related to attention, learning, and impulse control. Moreover, there is evidence that teenagers who start vaping are more likely to transition to traditional smoking later, reversing the decline in youth smoking rates seen over previous years.

Second-Hand Smoke: While e-cigarettes produce vapor rather than smoke, concerns about second-hand exposure still exist. The aerosol from e-cigarettes can contain nicotine and other potentially harmful substances. Although the risks are considered to be lower compared to traditional cigarettes, non-users, particularly vulnerable populations like children and pregnant women, should avoid exposure.


The impact of vaping on health is an intricate issue that resists easy answers. While e-cigarettes undeniably cut out the tar and numerous harmful substances produced by burning tobacco, they bring their own health risks to the table. From lung complications like vaping-associated lung injury (VALI) to cardiovascular effects such as elevated heart rate and blood pressure, the consequences of vaping cannot be taken lightly. Further complicating the picture is the alarming trend of rising vape usage among teenagers, which presents not only potential physical harm but also the danger of nicotine addiction and consequent cognitive impairment. Even second-hand exposure to e-cigarette vapor can be a matter of concern, particularly for vulnerable populations like children and pregnant women.

In the absence of comprehensive, long-term studies, a cautious approach to vaping is imperative. Both public health authorities and individual users must push for and pay close attention to further research that aims to unpack the full range of health implications tied to e-cigarette use. As it stands now, e-cigarettes may serve as a ‘lesser evil’ for adult smokers looking to quit, but they are not without risks and should be used with caution and full awareness of their potential health impacts.
