Nic salt, short for nicotine salt, refers to a type of nicotine that is commonly used in e-liquids for electronic cigarettes or vape devices. It differs from traditional freebase nicotine, which is the form typically found in tobacco leaves. Nicotine salt is created by combining nicotine with an organic acid, resulting in a modified form of nicotine that is smoother to inhale and allows for higher concentrations of nicotine to be used without causing excessive throat irritation.

One of the key advantages of nicotine salt is its ability to deliver nicotine more efficiently into the bloodstream compared to freebase nicotine. This means that vapers can experience a quicker and more satisfying nicotine hit, similar to the sensation provided by smoking traditional cigarettes. The higher nicotine levels in nic salt e-liquids are particularly appealing to individuals who are transitioning from smoking to vaping, as it can help satisfy their nicotine cravings more effectively.

Nicotine salt e-liquids are often used in smaller, low-wattage devices known as pod systems. These devices, in combination with nic salt e-liquids, are designed to provide a smoother and more enjoyable vaping experience, especially for individuals who prefer a higher nicotine strength.
