Health Considerations: Naturally Extracted E-Liquids vs. Disposable Vapes 

Disposable vapes and naturally extracted tobacco e-liquids both deliver nicotine through vapor, but the similarity ends there. What separates them is what else you are inhaling: the flavorings, the additives, and the chemicals that come along for the ride.

Research has found trace metals, synthetic flavoring compounds, and thickening agents like vitamin E acetate inside certain disposable vapes. Naturally extracted tobacco (N.E.T.) e-liquids take a different approach, using real tobacco leaves as the flavor source and disclosing every ingredient on the label. The result is two products in the same category with fundamentally different ingredient profiles.

This article compares what is inside disposable vapes with what is inside N.E.T. e-liquids, explains the research behind the key risks, and outlines what to look for if ingredient transparency matters to you. It is not a medical recommendation. It is a factual comparison of ingredients and the evidence available on each. 

What’s Inside Disposable Vapes?

The Base Ingredients: PG and VG

Both disposable vapes and N.E.T. e-liquids use a base of propylene glycol (PG) and vegetable glycerin (VG). PG is a colorless, odorless liquid that carries flavor effectively. VG is a thicker, viscous liquid that produces denser vapor. Manufacturers mix these at different ratios depending on the intended draw style and vapor density. Under FDA guidance, both PG and VG are “generally recognized as safe” for ingestion, though long-term inhalation data remains limited.

Where Disposable Vapes Add Unknowns

Beyond the PG/VG base, disposable vapes add nicotine (often synthetic) and flavoring compounds that may include artificial ingredients not fully disclosed on the label. The ingredient transparency gap is the core problem: most disposable vape labels do not itemize every compound in the flavoring blend, making it difficult for consumers to evaluate what they are inhaling.

Research has identified several specific concerns:

• Trace metals: A study published in Environmental Health Perspectives found that e-cigarettes expose users to toxic metals including arsenic, lead, chromium, and nickel. Researchers discovered higher metal concentrations in the aerosol and tank samples, hypothesizing that contact between e-liquid and the heating coil triggers a chemical reaction that introduces metals into the vapor.
• Synthetic flavorings: Disposable vapes use a combination of artificial and natural flavoring compounds to create profiles like candyfloss, bubblegum, and fruit blends. The specific chemicals in these blends are rarely disclosed. Some flavoring compounds that are safe for ingestion have not been tested for safety when inhaled.
• Vitamin E acetate: During the 2019 EVALI (E-cigarette or Vaping Product Use Associated Lung Injury) crisis, CDC researchers found vitamin E acetate in the lung fluid of 94% of EVALI patients across 16 states. This synthetic compound was used as a thickening or diluting agent in certain e-liquids. Healthy control patients showed no vitamin E acetate in their lung fluid.
• Diacetyl and related compounds: Some flavored e-liquids have contained diacetyl, acetyl propionyl, and acetoin, compounds associated with occupational respiratory concerns documented by the CDC and NIOSH. These compounds are used to create buttery or creamy flavor profiles. 

What N.E.T. E-Liquids Contain Instead

Naturally extracted tobacco e-liquids derive their flavor directly from real tobacco leaves through a cold maceration process, rather than from synthetic flavoring compounds. The ingredient list for a N.E.T. e-liquid is typically short and fully disclosed: vegetable glycerin, propylene glycol, purified water, natural tobacco extract, and nicotine derived from tobacco leaves.

Because the flavor comes from the tobacco leaf itself, N.E.T. e-liquids do not require artificial flavors, synthetic sweeteners, or chemical flavoring compounds. This also means they do not contain the diacetyl, acetyl propionyl, or acetoin compounds found in some flavored disposable vapes. The absence of added sweeteners has a practical benefit as well: e-liquids without sweeteners produce significantly less coil buildup, extending the lifespan of pods and coils.

Are E-Cigarettes Harmful?

The question isn’t whether e-cigarettes are harmful, but rather how harmful are they? Studies have proven that the health risks of e-cigarettes are wide and varied, encompassing a slew of physical and mental ailments, not to mention the environmental impact of disposable vapes.

Physical Health Risks

The physical vape health risks are the most well-known, but that doesn’t mean that researchers and scientists have a comprehensive list of all the possible downsides.

We do know that disposable vapes contain nicotine, the main stimulant in the tobacco plant. Even when vape manufacturers have disposed of the tobacco leaf, nicotine remains an addictive and dangerous drug.

Here are some short-term effects of nicotine.  

• Boosted concentration 
• Dizziness 
• Headaches 
• Increased heart rate 
• Raised blood pressure
• Relaxation
• Spiked adrenaline

The short-term effects of nicotine are nothing compared to the long-term effects, including an increased risk of cardiovascular, respiratory, and gastrointestinal disorders.

In the long term, nicotine also:

• Affects cell proliferation, oxidative stress, and DNA mutation 
• Compromises reproductive health 

People who consume nicotine for extended periods are at increased risk of cancer, building resistance to chemo and radiotherapy, heart attacks, lung disorders, and a range of cardiovascular issues.

Vape Health Risks for Young People

Young people should be especially aware of both the mental and physical vape health risks.

The prefrontal cortex, the part of the brain that controls cognitive functions such as decision-making, reasoning, and personality expression, doesn’t mature until age 25. Studies show that the adolescent brain is sensitive to nicotine, and young people who consume nicotine increase their risk of developing psychiatric disorders and cognitive impairments later in life.

Nicotine can disrupt the formation of vital brain circuits that control attention, learning, and the individual’s susceptibility to addiction. On top of that, studies have shown that vaping nicotine can intensify symptoms of depression and anxiety, as well as increase stress levels.

According to a 2019 cross-sectional study of nearly 30,000 current e-cigarette users, frequent vapers are 2.4 times more likely to have a diagnosis of depression compared to never users.

With the health risks of e-cigarettes becoming more and more apparent, it’s no surprise that many vapers are looking for an alternative.

What Is N.E.T. E-liquid?

N.E.T. e-liquid, or naturally extracted tobacco e-liquid, is an alternative to the standard e-liquid that dominates the market.

It is made from real tobacco leaves, so there’s absolutely no synthetic nicotine. Artificial nicotine pales in comparison to the real smoky, woody sensation of tobacco, so you can expect bold flavors.

That’s another thing; N.E.T. e-liquids don’t contain artificial flavorings. All the flavorings come directly from the tobacco plant. There are no artificial flavors, fillers, or nicotine.

N.E.T. E-Liquid vs. Disposable Vapes

So, are disposable vapes worse for health?

The simple answer is yes. 

Although N.E.T. e-liquid still contains nicotine, and therefore still poses a health risk, it is less dangerous than standard e-liquid because it doesn’t contain any artificial flavorings. You get the authentic taste of tobacco and the peace of mind that comes from real ingredients. 

When you buy naturally extracted tobacco e-liquid, you know exactly what is in it, from the nicotine to the flavorings. In other words, you never have to worry about diacetyl, vitamin E acetate, or any other harmful synthetic chemicals. 

If this type of e-liquid replaced standard, artificial e-liquid in 2019, the EVALI crisis might never have happened. To safeguard yourself against unnecessary vape health risks, switch from disposable vapes to N.E.T. e-liquid.

Common Misconceptions

Myth: All vape products carry the same ingredient risks.

The ingredient profile varies dramatically between product categories. A disposable vape with undisclosed synthetic flavorings, a refillable device using a naturally extracted tobacco e-liquid, and a THC cartridge (the primary driver of the EVALI crisis) all have fundamentally different compositions. Grouping them together obscures the real differences in ingredient quality and transparency.

Myth: “Natural” on a vape label means the product is free from harmful additives.

The word “natural” is not regulated in the vaping industry and does not guarantee the absence of harmful compounds. A product labeled “natural flavors” may still contain synthetic nicotine, diacetyl, or other additives. The relevant question is not whether the label says “natural” but whether the manufacturer discloses the complete ingredient list and tests for specific excluded compounds.

Myth: The EVALI crisis was caused by nicotine vaping products.

The CDC investigation identified vitamin E acetate as the primary cause of EVALI, and the compound was overwhelmingly found in THC-containing products, not commercial nicotine e-liquids. However, the crisis exposed a broader issue: when e-liquid ingredients are not fully disclosed, consumers cannot evaluate what they are inhaling. This makes ingredient transparency relevant regardless of the specific compound involved.
