Nicotine salt e-juice allow consumers to vape higher nicotine strengths without the rough throat hit that is found in traditional e-juices when compared at the same nicotine level.
For example, if you were to vape a 30 MG e-juice made with freebase nicotine the throat hit would be intolerable, but if you were to vape 30 MG e-juice made with nicotine salt the throat hit would be much smoother.
