If you are new to e-liquids, the difference between nicotine salts and freebase nicotine can be difficult to understand. They both contain nicotine. But they are also formulated in different ways and can offer different experiences when used in compatible vaping devices.

Learning a bit about the basics will help you understand the specifications of the product you’re choosing.

What is freebase nicotine?

Many e-liquids use the traditional form of nicotine, freebase nicotine. It is nicotine in a form that has not been modified with an acid.

Freebase nicotine comes in a variety of strengths and can be found in a variety of vape devices. This type of e-liquid is associated with lower strengths, as the experience can get a little bit harsher when used at higher nicotine strengths.

When choosing vape delivery products, remember to look at the strength and the formulation of the nicotine. E-liquids can differ significantly.

What are nicotine salts?

They are a mixture of nicotine and an organic acid, usually benzoic acid. This alters the chemical composition of the nicotine. It makes high nicotine levels “smoother” to inhale than the same amount of freebase nicotine.

Nicotine salts are associated with lower-powered pod devices. But you must always use the e-liquid and device the manufacturer recommends.

In what way do they differ in throat sensation?

One of the most noticeable differences is throat sensation. The higher the nicotine, the more intense the throat hit of freebase nicotine.

Nicotine salts are typically made to impart a smoother effect at higher levels. This is not to say that they don’t have as much nicotine. In fact, some even have reasonably high levels of nicotine.

What about absorption?

Vaping delivers nicotine into the body. Regardless of the type of nicotine. The rate of absorption and the amount absorbed may vary based on a number of factors:

Nicotine level
The device
The duration of the puff
How it is used.

Formulation is only one component of the whole story, though. Just because one type feels smoother doesn’t mean that it provides more nicotine.

What devices do they use?

Device compatibility matters. Nicotine salts are typically utilized in lower-powered pod systems. Freebase nicotine can be found on all systems.

Be sure to verify the recommended nicotine strength and formulation for your specific:

Pod
Tank
Coil.

An inappropriate product may affect device performance and your experience.

How do you compare nicotine strengths?

Nicotine strength is typically listed on the package of the e-liquid, in either mg/mL or a percentage. Avoid comparing products by whether it is labeled “salt” or “freebase”.

For instance, two liquids may contain similar nicotine concentrations and use different nicotine formulations. Take time to read the label and choose carefully.

Final thoughts

Having this information is very helpful when changing devices or replacing an e-liquid. A product that works well in one setup might not suit another.

If you switch from freebase nicotine to nicotine salts, or vice versa, check the device requirements and nicotine concentration.
