Nicotine salts are an alternative form of nicotine found in e-liquids that provide a smoother vaping experience compared to traditional freebase nicotine. They are derived from the leaves of the tobacco plant and undergo a unique extraction process known as "salting," resulting in a more stable and bioavailable form of nicotine.

The main difference between nicotine salts and freebase nicotine is their molecular structure. Nicotine salts are naturally occurring in the tobacco plant and are combined with acids to create a more stable compound. This altered chemical structure allows nicotine salts to be absorbed more efficiently and quickly into the bloodstream, providing a faster nicotine delivery and a more satisfying experience for users.

There are a few benefits associated with nicotine salts:

1. Smoother throat hit: Nicotine salts provide a milder throat hit, making them ideal for individuals who find high levels of freebase nicotine too harsh.

2. Higher nicotine concentrations: Nicotine salts allow for higher concentrations of nicotine in e-liquids without compromising the smoothness of the vaping experience. This is particularly appealing for heavy smokers or vapers who crave a higher nicotine intake.

3. Faster nicotine absorption: Due to their unique composition, nicotine salts are absorbed into the bloodstream more rapidly than freebase nicotine, providing a quicker nicotine fix.

It's important to note that nicotine salts are primarily intended for use in low-wattage, pod-style devices or vape pens rather than high-powered devices commonly used for sub-ohm vaping. This is because the high nicotine concentrations in nicotine salt e-liquids can be too intense for sub-ohm vaping and may lead to a harsh or unpleasant experience.

As with any nicotine-containing products, caution should be exercised, especially for non-smokers or individuals who are not accustomed to nicotine use. It's always recommended to consult with a healthcare professional or vape expert to determine the appropriate nicotine strength and usage for your individual needs.
