Our Black Ice Menthol e-liquid is made with freebase nicotine, which is the traditional form of nicotine used in vaping. The main distinction compared to nicotine salts is the throat hit sensation. Freebase nicotine typically provides a more pronounced 'throat hit', especially at higher strengths, which many vapers find satisfying as it can mimic the feeling of traditional smoking. Nicotine salts, on the other hand, are designed to deliver nicotine more smoothly, with a much milder throat hit, even at very high concentrations. If you enjoy a strong flavour with a noticeable, refreshing kick at the back of your throat, our freebase Black Ice Menthol is an excellent choice.
