Nicotine shots are designed to be added to Shortfill e-Liquids and are usually unflavoured. Some may contain a menthol element which will add a cool feel to your Shortfill e-Liquid.
By adding a 'Nic Shot' to a Shortfill e-Liquid it will increase the nicotine strength. For example, by adding a 10ml Nic Shot to 50ml of 0mg e-Liquid it will create 60ml of 3mg e-Liquid.
Nic Shots are designed to be added to Shortfill e-Liquids and are not intended to be vaped on their own.
