Nic salts are a type of nicotine formulation used in e-liquids. Unlike traditional freebase e-liquid formulation, nicotine salts are created by combining nicotine with an organic acid. This chemical modification lowers the pH level of the nicotine, resulting in a smoother vaping experience even at higher nicotine concentrations. That smoothness associated with Nic Salts is the reason they have become the most popular e-liquid type. Check out our Nic Juice Multi-Buy deals on all Nic Salts.
