"Salt-Nic" refers to nicotine salt, a formulation commonly used in e-liquids. Unlike freebase nicotine, which can be harsh at higher concentrations, nicotine salt provides a smoother throat hit, allowing for higher nicotine levels without discomfort. In the case of Strawberry Ice - RAZ TN9000, the 5% / 50mg Salt-Nic formulation ensures a satisfying nicotine experience without sacrificing flavor or smoothness. It's perfect for vapers who prefer higher nicotine concentrations or those looking to curb their nicotine cravings effectively.
