Vaping has become increasingly popular in recent years, as more and more people are looking for a healthier alternative to smoking cigarettes. However, there is still a lot of confusion about what exactly is in vapes, and whether or not they all contain nicotine.

Nicotine salts are a type of nicotine that is found naturally in tobacco leaves. They are called "salts" because they are formed when nicotine is combined with an acid. Nicotine salts are different from the freebase nicotine that is typically used in e-liquids for vaping.

A nicotine shot is a concentrated form of nicotine that is typically added to shortfill e-liquids. Shortfill e-liquids are larger bottles of e-liquid that do not contain enough nicotine to make them a full strength e-liquid.
