What’s inside my vape juice?

Nowadays, you hardly ever get a whiff of cigarette smoke walking down the street. All thanks to e-cigarettes. According to research, the number of vape-users worldwide will increase to 55 million by 2021.

But what exactly is in e-cigarettes? What ingredients make e-cigarettes different from traditional cigarettes? Read on to find out.

Vegetable Glycerin (VG)

Also known as glycerol or glycerin, VG is a liquid derived from plant oils. It is the ingredient in e-juices that produces the smoke-like vapor when you exhale.

Compared to Propylene Glycol (PG), VG produces more vapor. However, the throat hit effect is lower. Additionally, it is a more viscous fluid and slightly sweeter than PG.

The FDA considers VG safe for human consumption. That is to say; there are no toxicity concerns related to the use of VG. In fact, there is data to support the non-toxicity of VG. The compound naturally occurs in foods. More importantly, VG’s desirable sweetness does not affect the flavor of the other ingredients.

It is a naturally occurring compound that has been tested and used medically for generations.

Propylene Glycol (PG)

Propylene Glycol (PG) is an odorless, tasteless, and colorless syrup. E-cig companies use it in e-juices since it is an solvent for many organic compounds.

Findings published in the New England Journal of Medicine indicate that propylene glycol (PG) and glycerol react to produce formaldehyde. In fact, the study estimated “in ‘vaped’ e-cigarettes, more than 2% of the” e-juice is “converted to formaldehyde-releasing agents, reaching concentrations higher than concentrations of nicotine.” While the verdict’s still out on the health risks of PG, one thing’s for sure — you can breathe easy with STEMJUICE, made without PG.


Nicotine is the stimulant in cigarettes, and also the addictive ingredient. Once it enters the bloodstream, nicotine increases heart rate, blood pressure, and respiration. In the brain, it increases dopamine levels, and as a result, improves your mood.

Unlike traditional cigarettes, e-cigs allow you to choose the level of nicotine you want. That’s because most e-cig companies are transparent about the amount of nicotine in their e-juice.

STEMJUICE nicotine strengths in e-juice:

  • 0mg/ml: No nicotine. For people who want to quit smoking or experience vaping without nicotine.
  • 3mg/ml to 6mg/ml: Low levels of nicotine. For tobacco users who smoke light cigarettes or less than half a pack of cigarettes a day.
  • 2.5% nic salt: For people who smoke less than a pack of cigarettes. Medium to high levels of nicotine.
  • 5% nic salt: For people who want a higher concentration of nicotine.


STEMJUICE flavors include Tobacco, Tobacco mix, Tobacco blend and Menthol.

The Safe Ingredient That You Won’t Find Anywhere Else

We removed harmful substances

The problem is, many e-cigarette brands contain harmful substances, toxic chemicals, and heavy metals that can cause lung damage, such as formaldehyde, vitamin E Acetate, diacetyl or hydrogen cyanide. For instance, diacetyl, a chemical used to create the buttery flavor in popcorn, is safe to ingest, but when inhaled diacetyl can cause Obliterative Bronchiolitis.

Some manufacturers don’t reveal the blend ingredients of their flavors to avoid copycats, but STEMJUICE does not contain any of these substances. We care about our users & vaping as a whole, so we set out to revitalize the vape experience with a scientifically-researched e-juice. STEMJUICE is committed to transparency, and that’s why we’ve published our e-juice test results right here:

…and added plant stem cells

The research performed on our special ingredient, which is made from fresh green apples from Switzerland— showed that these patented plant stem cell extracts are not only safe for use in ejuice, but also can improve your lung vitality.

Just like humans, plants also have stem cells. These stem cells used in our e-juice are backed by thorough clinical research demonstrating rejuvenation of the face and body. They’re great for increasing the skin elasticity and protect the longevity of skin cells.

We have invested years of clinical research to perfect a cleaner, natural smoking experience and eliminate toxic chemicals from e-juice. STEMJUICE is dedicated to revitalized the vaping experience, and transforming the industry with scientifically-backed products.
