Nicotine salts, or Nic Salts, are a type of nicotine that is naturally found in tobacco leaves. Unlike the freebase nicotine commonly used in traditional e-liquids, nicotine salts are formed through a process of combining the nicotine with an acid. This results in a more stable molecule that allows for higher concentrations of nicotine to be used in e-liquids without the harsh throat hit often associated with high nicotine content
