Nicotine salts are a type of nicotine formulation that combines nicotine with an organic acid, typically benzoic acid. This combination results in a smoother vaping experience compared to traditional freebase nicotine. Nicotine salts are often used in e-liquids and vapor products, providing a more satisfying nicotine hit without the harshness associated with higher concentrations of freebase nicotine. They are popular among vapers who seek a more cigarette-like experience or those looking to curb their nicotine cravings more effectively.
