VG Vs PG - What's The Difference And How To Pick The Perfect Ratio

VG Vs PG - What's The Difference And How To Pick The Perfect Ratio

Vape juice is made up of liquid, flavor, and nicotine. You have a choice between two different types of juice, and they are called “PG” and “VG.” These two liquids are part of the alcohol chemical class, but they must not be confused with alcohol; you can’t become intoxicated by ingesting them. They are known as “sugar alcohols,” and they can be found in several foods.

What Are PG and VG?

PG stands for “Propylene Glycol.” PG is a petroleum byproduct that doesn’t have a smell or a taste, and it isn’t sticky. The “throat hit” that PG gives users is described as similar to the sensation that you receive from smoking tobacco. It also does a better job of holding flavor than VG, so more people like it.

VG stands for “Vegetable Glycerin,” and it comes from vegetable oils. This is the e-liquid for you if you are in favor of a thick sensation in your vapor. VG is slightly sweet and creates a hit that is much smoother than PG. It is the e-juice of choice for those who participate in sub-ohm vaping.

How is It Used?

PG can be found in many different products other than e-juice. They include all types of pet food other than cat food, many different cosmetics, oral medications, toothpaste and nicotine inhalers.

PG and VG are necessary for e-juice because when they are heated, they create the vapor that you can inhale. These two liquids create safe e liquid because they do not cause medical conditions like oils do. Oils that are inhaled are responsible for causing lipoid pneumonia.

The type of sensation that you are seeking will help you determine the winner between the VG vs PG contest.

Is it Safe?

Studies have been performed on PG, and these studies have determined that PG is safe for human consumption. The FDA also considers PG to be safe enough to be added to food. The fact is that these studies did not examine whether or not it is safe to inhale the substance, but one longitudinal study done in 1947 did find that PG taken in aerosol form was “completely harmless.”

A study done in 2010 on a combination of propylene glycol and glycol ethers discovered that the mixture may increase instances of childhood asthma, eczema and hay fever, but the cause was determined to be the glycol ethers.

PG may not be safe for cats because studies have discovered a correlation between PG and the condition that afflicts cats called “Heinz body anemia.” Therefore, experts suggest that you exercise caution when you are inhaling with PG in the presence of your cats.


What Is it Used for?

Vegetable glycerin is an artificial sweetener, but it can also be found in several products. Some of these products include the following:

  • Toothpaste
  • Dental care products
  • Jellies, pills and medicinal creams
  • Baked goods
  • Soaps and hand creams
  • Pet food
  • Cosmetics

Is it Safe?

The FDA has determined that VG is “generally recognized as safe.” It is considered to be safer than most products in existence. According to the SIDS Assessment Profile, VG has a low toxicity profile when it is eaten. It is also not very likely to cause irritation to your skin or eyes. These studies demonstrate that VG is safe for human consumption, but extensive studies have not been done on VG in its aerosol form. One study done in 2008 specifically sought to answer the question about inhaled VG, and it found that inhaling VG posed minimal risks.


If you are allergic to PG, VG would be an excellent alternative because the risk of an allergy to VG is extremely low. The exception would be if you have an allergy to palm oil or coconut oil, but these allergies are very rare. People with diabetes have difficulties metabolizing VG, but the small amount of VG used in vaping would not present a problem to these people.

How Do You Find the Perfect Ratio between PG and VG?

High PG

If you are used to smoking, you may wish to experience the “kick” you used to get when inhaling the smoke. PG in combination with nicotine can give you this sensation better than VG can. Since PG holds flavor better than VG, it is also the more flavorful choice.

If you wish to vape in public, you may want to remain inconspicuous, and PG will do this for you. This method produces less vapor, but be aware that you cannot do this everywhere.

High VG

If you want to experience smoothness, you can have this with VG. It will also feel thicker inside your mouth. Since the flavor isn’t as strong with VG, all you need to do is increase the power to increase the vapor. Make sure that you remain within your atomizer’s voltage/wattage limits. If not, your hits could be too dry, or you could damage your equipment.

VG is also the best choice if you want to create huge clouds of smoke. All vape competitors use 100% VG for maximum vapor.

Which Equipment Should I Use?

Most vape pens and atomizers will work with both PG and VG. The performance will vary though:

- Clearomizers are recommended for high PG use. You can also use a VG/PG ratio of 50:50.

- Sub-ohm tanks are suitable for high VG fluid because they are powerful enough to be able to handle thicker VG juice. Most people don't like using these with high PG  because the "hit" on the throat just becomes too strong.

Finding the safest vape juice depends on the type of experience you are seeking. If you favor tobacco flavors, fruits or beverages, try PG because this will allow the flavor to blend better. If you enjoy yogurt, custard or cream flavors, VG would work better for you. This gives you a thick sensation in your mouth that makes your vaping experience seem as if you are having dessert. Let your taste buds do the choosing for you.
