WARNING

In recent years, with the surge in demand for customized vape flavor, vapors are very concerned about questions such as “What is freebase nicotine”, “Freebase nicotine vs salt nic ”, “Freebase nicotine vs salt nic” and “How to use freebase nicotine”. Vapors are keen to understand the principles, fit scenarios and differences between this traditional form of nicotine and nicotine salts for a more precise tobacco control experience.

I. Freebase nicotine vape juice

1. What is freebase nicotine?
Freebase nicotine is the pure base form of nicotine (pH ≈ 8.5), which enhances bioavailability by removing protons (H⁺), and its molecules are more likely to penetrate human cell membranes.

2.Historical Applications
Originated in the traditional tobacco industry in the 1960s and is now the dominant form of nicotine in sub-ohm vape.

II. how freebase nicotine works and suitable devices
1. How freebase nicotine works？

High-power devices (≥40W) heat the vape juice;

Free base molecules are atomized at high temperature (200-300°C);

Nicotine rapidly enters the bloodstream through the alveoli of the lungs;

High pH value stimulates the throat to produce a strong throat hit.

2. Best adapted devices recommendation
Sub-ohm vape: support 0.15-0.3Ω coil resistance.

Mechanical vape / regulator box mod vape: need to match with high VG vape juice (VG ≥ 70%) to avoid leakage.

3. How to choose vape juice strength formula
Low power devices (≤30W): 3-6mg/ml

High power devices (≥50W): 1.5-3mg/ml

Concentration too high will lead nicotine overdose symptoms.

III. Free base nicotine vs. nicotine salt

1. Taste experience
Free base nicotine: strong throat hit, large amount of smoke, suitable for cloud chasing vapors;
Nicotine salt: smooth and smooth throat hit, suitable for normol vapors or quit smoking.

Nicotine Salt has a nicotine absorption rate close to that of real cigarettes due to the addition of benzoic acid, which relieves the addiction faster;

Free base requires higher power and inhalation duration to achieve the same level of satisfaction.

3. Device compatibility
Freebase is only compatible with low resistance coil device.

Nicotine Salt is suitable for high resistance coil device (1.0Ω and above).

4.Cost
The cost per milliliter of free base vape juice is 30%-50% lower than nicotine salt.

5.Health
Free base high temperature atomization may produce more formaldehyde; nicotine salt due to acidic additives, long-term inhalation of the oral mucosa impact to be studied.
