In the ever-evolving world of e-cigarettes, there are two terms that are quite popular among enthusiasts: freebase nicotine and nicotine salts. Both terms play a vital   role in e-liquids, but they fulfill different preferences and needs. This article aims to   delve into the nuances of freebase nicotine and nicotine salts, focusing on their differences, benefits, and ideal uses.

Origin

Freebase nicotine has been the standard in nicotine products since the 1960s, thanks to the innovation of tobacco companies. This form of nicotine is pure, without any added compounds, making it the most potent form when heated and inhaled.

Nicotine salts, on the other hand, are a more recent development. They are created by combining pure nicotine with organic acids, resulting in a more stable and less volatile compound.

How They Work

Freebase nicotine has a higher pH and is therefore more alkaline. This high   alkalinity allows nicotine to be absorbed more quickly into the lungs and brain, resulting in a fast and intense nicotine hit.

Nicotine salts have a lower pH, which provides a smoother smoking experience.

The addition of benzoic acid or other organic acids helps reduce alkalinity, making   the vapor less irritating to the throat. This allows for a higher nicotine concentration. 

Nicotine Strengths

Freebase nicotine is usually available in lower concentrations, ranging from 3 mg to 18 mg per milliliter. This makes it ideal for smokers who like to vaporize frequently without the risk of nicotine overdose.

Nicotine salts are available in much higher concentrations, often between 20 and 50 mg per milliliter.

Characteristic aroma

Freebase nicotine is known for its ability to deliver strong, well-defined flavors. The purity of the nicotine makes the flavor of the e-liquids more pronounced, providing a   rich and satisfying experience. This makes it a favorite among flavor enthusiasts who use high-performance devices to maximize the flavor experience.

Nicotine salts flavor may not be as strong as e-liquids containing freebase nicotine, they provide a smooth and consistent flavor.  

Device Compatibility

Because of freebase nicotine lower concentration and higher vapor volume, it is best used with high-wattage devices, such as box mods and sub-ohm smoke

canisters, to provide an optimal vaping experience.

Nicotine salts are designed for low-wattage, low-power devices like pod systems.  Using them in high-wattage, sub-ohm devices can be harsh, cause leaking, and be overwhelming due to the high nicotine strength.

Health and Safety

Freebase nicotine has been around for decades and its safety is well documented. However, high alkalinity may cause throat irritation and discomfort, especially at higher nicotine concentrations.

Nicotine salts are relatively new and research into their long-term health effects is still ongoing, but current evidence suggests that their use in e-liquids is generally safe.
