Is Propylene Glycol Safe to Vape? (Side Effects, Safest Vapes)
Wondering if propylene glycol in your vape juice is safe?
High-quality vapes with propylene glycol (PG) are usually safe and non-toxic as long as they are free from nicotine and other harmful additives.
Nicotine and chemicals like diacetyl and vitamin E acetate in low-quality vapes and electronic cigarettes can cause serious health issues, like lung disease.
Let’s uncover what vaping propylene glycol entails and explore two safe vape options, along with other FAQs around the subject.

What is Propylene Glycol and Why is it Used in Vape Juice?
PG is a colorless, odorless, viscous liquid widely used as an additive in the food, cosmetics, and pharmaceutical industries.
It has a mildly sweet flavor and is sought-after for its ability to retain moisture in products.
The question is: Why is propylene glycol used in vape juice and e liquid?
PG, mixed with vegetable glycerine (or vegetable glycerin), forms the base of vaping liquids used by an electronic nicotine delivery system (ENDS), like vaping devices and electronic cigarettes.
These two ingredients help vaporize nicotine and flavoring in the vape juice or electronic cigarette liquid.
The e liquid vapors mimic tobacco cigarette smoke without actually burning any tobacco.
Now, vape juice manufacturers may use PG and VG in varying ratios to create different experiences.
Here’s exactly how PG affects your vaping experience:
- Gives a distinct throat hit while vaping.
- Creates a smooth and intense flavor experience.
- Produces fewer vapour clouds than vegetable glycerin and helps mimic the feeling of smoking a tobacco cigarette.
Is Propylene Glycol Safe to Vape?
Here’s the deal:
There’s limited research on the long-term effects vaping PG through an electronic nicotine delivery system. However, most studies and clinical trials indicate it’s safe for humans.
Most notably, the US Food and Drug Association (FDA) deems propylene glycol safe for use in food.
Moreover, while e cigarettes and vapes are relatively new products, PG has long been used to:
- Sweeten food products (think: your favorite tub of ice cream!)
- Solubilize oral, topical, and injectable medicines.
- Increase moisturizing benefits of personal hygiene products, like creams and lotions.
Fun fact: Propylene glycol is also used in conventional cigarettes to keep the tobacco moist and to prevent the cigarette from drying out.
What the studies say:
In a 2008 clinical trial, scientists studied the effects of PG inhalation on rats and dogs over three months. They concluded that PG inhalation had negligible impact on the subject’s lung tissue.
Further animal studies focused on epithelial cells proved that inhaling PG vapour in normal quantities is safe.
So, what are the safe levels of PG for humans?
As per a 2017 study, PG reaches toxic levels in the human body at a blood plasma concentration of over 3 grams.
The amount of PG inhaled via regular e cigarette use is 0.3-0.4 grams daily.
Even with very heavy vaping or e cigarette use, it’s hard to inhale PG in quantities that could cause toxicity.
While PG is generally safe, it may cause potential side effects in some people.
Potential Side Effects of Propylene Glycol
Here are some possible side effects of PG:
- Airway and lung inflammation
- Dry mouth and throat irritation
- Lactic acidosis in children
- Oral health damage(gum disease, weakening of teeth)
Note: These effects are uncommon and are associated with prolonged use or very high doses.
Now, you may be wondering:
If PG is safe to inhale, what in vape juice and electronic cigarette liquid makes them dangerous?
The two biggest culprits: Nicotine and other harmful additives like ethylene glycol and vitamin e acetate.
Like traditional cigarette smoking, vaping nicotine increases the risk of various health concerns. These include EVALI (E Cigarette and Vaping-Associated Lung Injury) and long-term damage to the lung tissue.
Similarly, flavoring agents like diacetyl could cause airway damage and lead to conditions like ‘popcorn lung.’
Does that mean you should quit vaping altogether?
Nope, we have a better idea!
Did you know: According to the Centers for Disease Control and Prevention (CDC), lung injury cases are more prevalent with the exclusive use of THC (a cannabis compound) in vape liquid than nicotine.

Other FAQs About Vaping Propylene Glycol
Here are a few other things you need to know about vaping propylene glycol:
1. Can Propylene Glycol Cause an Allergic Reaction?
Yes, PG may cause an allergic reaction in some people – however, it’s pretty uncommon.
Here are a few common symptoms of a PG allergy:
- Skin irritation or inflammation (contact allergy)
- Dry mouth and a cough
- Throat irritation
2. Can Propylene Glycol Interact with Other Substances?
At high temperatures (between 300°C-400°C), propylene glycol can turn into a harmful substance called formaldehyde.
The good news?
Most pod-based vaping systems are safe because they don't reach these high temperatures.
3. Are Bystanders at Risk of Propylene Glycol Inhalation?
No, bystanders are not likely to be at risk of PG inhalation caused by e cigarette vapour.
A 2012 study found that PG was almost undetectable in the air an hour after sampling. Some other studies detected varying levels of PG (0.1–2.2mg per cubic meter) in the air after sampling.
These numbers are significantly less than the Workplace Environmental Exposure Limit (WEEL) of 10mg per cubic meter over 8 hours set by the American Industrial Hygiene Association (AIHA).
Moreover, the overall health risk from PG is negligible compared to passively inhaling tobacco smoke from traditional cigarettes.
4. How Much Propylene Glycol do You Inhale While Vaping?
Honestly, there’s no definitive answer, as each vape and e cigarette vape liquid contain varying amounts of propylene glycol.
But studies suggest that an average e cigarette user may ingest anywhere between 0.3 to 0.45g of PG in a day.
Take Control Of Your Health & Opt for High-Quality, Nicotine Free Vapes
Existing studies and the FDA’s safety approval mean that propylene glycol is safe to use in vape and e liquid.
