If you’re a vaper, you may have heard of propylene glycol (PG), a common ingredient found in many e-liquids. PG is used as a carrier for flavorings and nicotine, and is generally recognized as safe by the FDA for consumption. However, when it comes to inhaling PG through vaping, there are some concerns about its safety.
Studies on animals have shown that even high concentrations of PG inhalation over an extended period of time doesn’t seem to lead to major health problems. However, it’s important to note that animal studies don’t always translate to humans. There is still a need for more research on the long-term effects of inhaling PG through vaping.
Despite the lack of conclusive evidence, many vapers still choose to use e-liquids that contain PG. Some argue that the benefits of quitting smoking outweigh the potential risks of inhaling PG. Others prefer the taste and throat hit that PG provides. Ultimately, the decision to use e-liquids with PG is up to you and your personal preferences.
What is PG in Vapes?

If you’re new to vaping, you may have heard the term “PG” thrown around a lot. PG stands for propylene glycol, which is a clear, odorless liquid that is used in many different products, including e-liquids for vapes. PG is a common ingredient in e-liquids because it helps to create the vapor that you inhale when you use your vape.
PG is generally recognized as safe by the US FDA, and has been used in many different products for many years. It is commonly used as a food additive, and is also found in many different medications and cosmetics.

In e-liquids, PG is used as a base ingredient that helps to create the vapor that you inhale. When heated, PG turns into a vapor that is easy to inhale, and it helps to carry the flavor and nicotine in your e-liquid.
While PG is generally considered safe, some people may have an allergic reaction to it. Symptoms of an allergic reaction to PG can include throat irritation, coughing, and skin irritation. If you experience any of these symptoms, you may want to switch to an e-liquid that contains more vegetable glycerin (VG) than PG, or switch to a different type of vape altogether.
Is PG Safe in Vapes?
If you’re a vaper, you might be wondering whether propylene glycol (PG) is safe to inhale. The good news is that PG is generally considered safe for vaping. In fact, PG has been used in asthma inhalers and nebulizers for decades without any major issues.
PG is a colorless and odorless liquid that is used as a base in many e-liquids. It helps to produce the vapor that you inhale when you vape. PG is also used in many other products, such as food, cosmetics, and pharmaceuticals.
According to the FDA, PG is generally recognized as safe (GRAS) for consumption. This means that it is safe to ingest in small amounts. However, some people may be sensitive to PG and experience irritation in their throat or lungs. If you experience any discomfort while vaping, you should stop using PG-based e-liquids and switch to a vegetable glycerin (VG) base instead.
It’s important to note that not all e-liquids are created equal. Some low-quality e-liquids may contain harmful additives, such as nicotine, diacetyl, and vitamin E acetate, which can cause serious health issues. When choosing an e-liquid, make sure to look for high-quality products that are free from harmful additives.

Scientific Studies on PG Safety
If you’re wondering whether PG is safe in vapes, scientific studies can provide some insight. Here are a few key takeaways from recent research:
-
A 2020 study published in the American Journal of Physiology found that PG and VG (vegetable glycerin) can reduce growth and survival of airway epithelial cells, which could potentially lead to respiratory issues. However, it’s worth noting that the study used concentrations of PG that were higher than what’s typically found in e-liquids.
-
Another study from 2017, published in the Global Journal of Pharmaceutical Sciences, reviewed existing animal and human studies on PG inhalation and concluded that it is safe at the concentrations found in e-cigarettes.
-
A 2014 study from researchers at the University of California, Riverside, found that some e-liquids contained harmful chemicals, including acrolein, a known respiratory irritant. However, the study did not specifically focus on PG.
Overall, while there is some evidence to suggest that high concentrations of PG could potentially be harmful to respiratory health, the concentrations typically found in e-liquids appear to be safe. However, it’s important to note that the long-term effects of vaping are still not fully understood, and more research is needed to fully understand the potential risks.
Effects of PG on Human Health
Propylene glycol (PG) is a common ingredient found in many vape liquids. While it is generally regarded as safe by the FDA, there are still concerns about its effects on human health. Here, we’ll discuss the short-term and long-term effects of PG on your health.
Short-Term Effects
In the short term, inhaling PG can cause some mild side effects. These can include:
- Throat irritation
- Dry mouth
- Headache
- Allergic reactions
Most of these side effects are mild and go away on their own, but if you experience persistent symptoms, it’s best to talk to your doctor.
Long-Term Effects
The long-term effects of inhaling PG are not yet fully understood. Some studies have suggested that long-term exposure to PG can cause lung inflammation and damage, but more research is needed to confirm this.
It’s important to note that the long-term effects of vaping in general are still being studied, and there is much we don’t yet know about the potential risks. If you’re concerned about the long-term effects of vaping, it’s best to talk to your doctor.
In conclusion, while PG is generally considered safe by the FDA, there are still concerns about its effects on human health. Short-term exposure to PG can cause mild side effects, while the long-term effects are still being studied.

Regulations on PG in Vapes
When it comes to the safety of vaping, the regulations vary by country. In the United States, the Food and Drug Administration (FDA) regulates the manufacturing and distribution of e-cigarettes and vaping products. In 2016, the FDA extended its authority to include all tobacco products, including e-cigarettes and their components.
The FDA requires manufacturers to submit a premarket tobacco product application (PMTA) for any new tobacco product, including e-cigarettes, that hit the market after August 8, 2016. The PMTA must include information on the product’s ingredients, manufacturing process, and health risks. The FDA reviews the PMTA to determine if the product is “appropriate for the protection of public health.”
In the European Union, the regulations are stricter. The Tobacco Products Directive (TPD) sets out specific requirements for e-cigarettes and e-liquids, including limits on nicotine strength, maximum tank sizes, and child-resistant packaging. The TPD also requires manufacturers to submit a notification to the competent authority of the Member State where the product is placed on the market.
In Canada, the regulations on vaping are set by the Tobacco and Vaping Products Act (TVPA). The TVPA requires manufacturers to submit a notification to Health Canada before selling a vaping product. The notification must include information on the product’s ingredients, health risks, and manufacturing process.
Overall, it is important to pay attention to the regulations in your country and to purchase vaping products from reputable manufacturers who follow these regulations.
Alternatives to PG in Vapes
If you are looking for alternatives to PG in vapes, there are a few options available. Here are some of the most popular alternatives:
Vegetable Glycerin (VG)
VG is a natural compound derived from vegetable oils. It is commonly used as a base for e-liquids and is known for producing thick, dense vapor. VG is also sweeter than PG, which can affect the flavor of your e-liquid. It is generally considered safe for vaping, but some people may experience allergic reactions to it.
Polyethylene Glycol (PEG)
PEG is a synthetic compound that is often used as a substitute for PG in e-liquids. It has a similar consistency and vapor production to PG, but is less harsh on the throat. PEG is generally considered safe for vaping, but some studies have suggested that it may produce harmful chemicals when heated to high temperatures.
1,3-Propanediol (PDO)
PDO is a synthetic compound that is similar to PG in terms of consistency and vapor production. However, it is less harsh on the throat and has a slightly sweet taste. PDO is generally considered safe for vaping, but it is not as widely used as PG or VG.
Medium Chain Triglycerides (MCT)
MCT is a type of fatty acid that is derived from coconut oil. It is sometimes used as a substitute for PG or VG in e-liquids. MCT is generally considered safe for vaping, but it can be harsh on the throat and may produce harmful chemicals when heated to high temperatures.
When choosing an alternative to PG in your e-liquid, it is important to consider your personal preferences and any potential health risks. Always read the ingredients list carefully and do your research before trying a new product.
