Nic Salts and Freebase
Within vape e-liquids, there are two different types of nicotine that are used. Freebase (or standard) as well as nicotine salts. They both offer two very different ways of vaping.
Freebase offers more of a stronger and harsher throat hit and a slower release of nicotine into your bloodstream. These normally come in strengths of 3mg, 6mg, 12mg, and 18mg.
Nic-salts have a smoother throat hit however are absorbed into the blood at a much faster rate. Often this is referred to as a “head-hit”. These normally come in strengths of 5mg, 10mg and 20mg.
