Nicotine salt requires a higher temperature to vaporize, as the ions do not travel smoothly to the nicotine receptors in our body, the benzoic acid is an ingredient which is used to vaporize the nicotine salt at a much lower temperature. This results in lowering the pH level, pH level is an indicator to measure acidic content in the element. Due to lower pH content, nicotine salt will have a smoother throat hit. This process in nicotine salt helps you to vape a higher nicotine content.
