Nicotine salt is for those wanting to vape a higher nicotine strength without getting a rough throat-hit. This type of nicotine is also absorbed into the bloodstream a lot faster than traditional nicotine. Nicotine salt is the natural nicotine salts found in tobacco plants with the addition of benzoic acid. This is a purer version than regular nicotine used in e-liquid and can satisfy the user after a couple of puffs.
