In the world of vaping, one of the most confusing things for users especially beginners is understanding the nicotine strength in e-liquid.
Numbers like โ3 mgโ, โ12 mgโ, or even โ30 mgโ are often seen on bottles, but what do these numbers actually mean?
1. What Does Nicotine Strength Mean?
Nicotine strength indicates how much nicotine (in milligrams) is contained in every 1 milliliter (ml) of e-liquid.
So, if a bottle is labeled โ30 mgโ, it means that every 1 ml of liquid contains 30 mg of nicotine.
The calculation is simple:
- 30 ml of 30 mg Saltnic โ 30 mg ร 30 ml = 900 mg total nicotine
- 60 ml of 3 mg Freebase โ 3 mg ร 60 ml = 180 mg total nicotine
So, even though the saltnic bottle is smaller, its total nicotine content is 5 times higher than the regular freebase.
2. Freebase vs. Saltnic: Whatโs the Difference?
There are two main types of nicotine used in the vape world:
Freebase Nicotine
- The purest form of nicotine, which is alkaline.
- Provides a strong throat hit (TH) and a โkickโ in the throat.
- Suitable for users who like a strong flavor and thick vapor.
- Generally used in high-wattage devices (30โ100 W).
Salt Nicotine (Saltnic)
- The result of a reaction between nicotine and organic acids (like benzoic acid).
- Has a lower pH, making it smoother on the throat.
- Nicotine is absorbed into the bloodstream faster โ satisfying the craving more quickly.
- Ideal for low-wattage pods (10โ25 W) and users who want high nicotine without a harsh throat hit.
3. Why Does Freebase Feel Stronger Even Though the Nicotine is Lower?
The secret lies in the pH and heating temperature:
- Freebase โ High pH โ Harsher sensation โ Stronger throat hit.
- Saltnic โ Low pH โ Smoother sensation โ Milder throat hit.
Furthermore, freebase liquid is typically mixed with more PG (Propylene Glycol), which enhances the โscratchyโ sensation in the throat.
