How to choose e-juice? E-liquid main ingredients in detail

If you desire a sweet, smoky vape with a strong "throat hit": opt for a juice high in VG, high in nicotine, and with a minty flavor.

If you prefer a softer, more mellow vape: go for a medium PG/VG juice with low to medium nicotine content.

If you want a unique flavor experience: select a low-nicotine juice.

If you seek a life without excitement: go for a high PG, high nicotine, pure menthol-flavored juice.


A ton of newbies only think about "flavor" and "brand" when picking out juice (internationally known as E-Liquid or E-Juice), just to end up disappointed. Learning about the components of juice and how they function won't just help you choose the right juice, but will also give you insight into what you're inhaling (and make you feel better about it). Geekvape store wants to assist more vaping newcomers.

Vape juices consist of "Nicotine Content", "Propylene Glycol (PG)", "Vegetable Glycerin (VG)", "Flavors", and "Flavorings".


Nicotine Content:

Also called nicotine, it's the addictive component in cigarettes. Trace amounts of nicotine in vape juices ensure that the addiction is satisfied.

Pure nicotine is highly toxic, and the nicotine content of the juice is usually expressed as XXmg/ml. Generally, when buying vape juice, you can choose 24mg/ml (very high concentration), 18mg/ml (high concentration), 12mg/ml (medium concentration), 6mg/ml (low concentration), or 0mg/ml (nicotine-free). Nicotine concentration above 24mg/ml is very harmful to the body, so basically we haven't seen any manufacturers produce such concentrations, but customers can mix their own (be careful, this is a game of life!).

Nicotine is the primary reason why e-cigarettes give a "throat hit". The higher the nicotine concentration in the juice, the stronger the "throat hit", but it also diminishes the flavor of the juice. Many newbies ask, "What nicotine strength do I need?" This is hard to answer because everyone's addiction and need for a "throat hit" differ, as does the frequency of e-cigarette use. Also, different atomizer structures, cartridge settings, and airflow sizes affect the "throat hit" and "nicotine absorption efficiency in the lungs", creating different personal experiences. Before I switched to vaping, I used to smoke a pack of Marlboro Reds a day, and an 18mg/ml nicotine concentration is a bit high for me. When selecting nicotine concentration, it's suggested to start with 12mg/ml, then "adjust as needed" (12mg/ml nicotine concentration is also recommended by foreign manufacturers; it strikes a good balance between "throat hit" and "juice flavor", meaning it satisfies your addiction without sacrificing too much flavor).

Nicotine is always harmful, which is why many criticize e-cigarettes as unhealthy. But compared to the 4,000+ harmful substances produced by burning cigarettes, nicotine is relatively benign. Want to quit smoking healthily? Just don't smoke anything!


Propylene Glycol (PG):

It's a common pharmaceutical and food additive, hygroscopic, slightly sweet, odorless, colorless, and transparent, with a viscosity similar to water. The U.S. Food and Drug Administration (FDA) considers PG "generally safe for human consumption".

PG is one of the base ingredients in e-cigarette juices (carrying nicotine and flavorings), mainly used to "carry most of the flavor of the juice" and produce "a small amount of vapor" and "throat hit". The main purpose is to "carry most of the flavor" and create "a small amount of vapor" and "throat hit". If you prefer "big clouds", steer clear of juices with high PG content.

Although PG is generally safe for humans, a few people may experience side effects like throat irritation, phlegm, allergies, etc. These side effects are brief and mild and can be avoided by quitting vaping or switching to a juice with lower PG content (some juices are PG-free).


Vegetable Glycerin (VG):

More commonly known as a pharmaceutical and food additive (used in making cakes, chocolates, and other sweets), it's highly hygroscopic, sweeter than PG, odorless, colorless, and transparent, with a viscosity similar to cooking oil.

VG is another base ingredient in e-cigarette juices (carrying nicotine, flavorings), mainly used to produce "large vapor clouds".

VG has no known side effects on the human body (I've never heard of anyone being allergic to chocolate...), but due to its viscous nature, it can be slightly more challenging to clean an atomizer.

If you notice a juice that's sticky, it's a sign it's high in VG.


Flavorings & Flavors:

It's self-explanatory—different flavors of vape juices are flavored using flavoring agents. Flavorings & flavors tend to stick more to PG (relatively speaking, or else wouldn't those pure VG vape juices be tasteless?). The flavor of the juices is not as potent as their aroma. However, it's worth noting that the higher the nicotine concentration in the juice, the less likely the flavorings & flavors will be noticeable to the palate and nose. Some flavors and fragrances can also deliver a "throat hit", like menthol...

There are thousands of vape juice manufacturers out there, but vapers (e-cigarette users) who can should aim for big brands and international names. Those small workshops and shady companies producing vape juices often use flavorings & flavors that are hard to guarantee safety, resulting in even worse taste.


Please note:

The same juice may provide vastly different experiences with different atomizers and settings.

Because vape juices are customizable, some manufacturers and vapers add other ingredients to them: water, vodka, sweeteners, etc...

All things considered, vape juice is a relatively safe, low-risk substance, and products from reputable manufacturers can be used without worry.

And armed with the knowledge from this article, you won't feel completely lost when choosing a vape juice.
