Salt nicotine, or “nicotine salt,” is a form of nicotine that is naturally found in tobacco leaves. It differs from freebase nicotine, which is commonly used in traditional e-liquids. Salt nicotine is more stable, allowing for higher nicotine concentrations without the harsh throat hit. This makes it ideal for users who prefer a smoother vaping experience, especially in devices like pod systems. It also gets absorbed into the bloodstream faster, offering a quicker and stronger nicotine hit.
