Nicotine shots are small 10ml bottles of concentrated nicotine designed to be added to nicotine-free shortfill e-liquids. They provide a compliant way to customise nicotine strength without affecting the overall flavour profile of the e-liquid.
Nicotine shots are available in different formulations, including freebase nicotine and nicotine salts, as well as flavourless and lightly flavoured options. They are most commonly used with shortfill e-liquids to create a personalised nicotine strength while maintaining the intended VG/PG balance.
