Nicotine Salt E-Juice
Nicotine salt based vape juices simulate smoking more closely than traditional freebase e-liquids because of how they are absorbed. Nic Salts liquids come in higher concentrations than others but their lower alkalinity provides for smoother throat hit and better absorption, and they should only be used in low wattage mouth to lung style devices.
Nicotine salt is the natural state of nicotine in the tobacco leaf. Nicotine salt based vape juice resembles the experience of cigarette smoking more closely than that of freebase nicotine, as it increases nicotine absorption in the blood. Nic Salts come in higher concentrations than regular e juice, however, their lower alkalinity provides for smoother throat hit and better absorption.
If you are looking to try nicotine salt e-liquid for the first time, make sure you have a high-resistance-low-wattage device, not a high-wattage sub-ohm device. Start with shorter puffs and in lower frequency, as compared to regular freebase nicotine e juice, to avoid the risk of taking excessive nicotine.
