A range of nicotine salt based e-liquids.  Nic Salts are high strength liquids to 20mg yet have much less throat hit than normal e-liquids.  A 20mg nic-salt e-liquid feels more like 6-12mg on the throat.

Nic-salt liquids also absorb faster than normal giving a more realistic nicotine hit than traditional e-liquids.  

These liquids suit people who may have been heavy smokers, looking for a better nicotine hit, yet without the harsh throat hit.
