Salt Nic Shot by Zap! Juice should not to be vaped on its own; it is a salt nicotine booster shot, designed for use with shortfill eliquids.
When mixed into the shortfill of your choice, it will increase the nicotine content of the eliquid. For example, adding this 18mg, 10ml salt nic shot to a 50ml, 0mg eliquid, will create a 3mg, 60ml e-liquid.
Salt nicotine interferes less with the liquids overall flavour and provides a more potent nicotine hit with less of a throat hit, for a smoother vape. Please see our blog for more information on Nicotine Booster Shots and Shortfill Eliquids
