The question at hand is:
What is Nicotine Salt?
Here is an answer!
Nicotine salt is the form of nicotine found in tobacco leaves. Unlike the nicotine ordinarily used in e-juice, these salts aren’t just nicotine; they’re compounds containing nicotine and another organic components. This could be in combination with one or more of the other chemicals in tobacco leaves, but the result is the same – a more stable molecule is formed.
The form of nicotine ordinarily used in e-liquid is called “freebase” nicotine. This is nicotine not bonded to anything else, and is generally considered preferable for vaping and other purposes because it’s a more “volatile” (i.e. easily vaporized) form of nicotine.
Why nicotine salt juice are popular in this days?
This is the reason.
1. You’ll get more nicotine, more quickly
2. You can use higher-nicotine juices
3. Nicotine salt e-juice has a longer shelf-life
4. You don’t need a powerful device
So nicotine salt is really smooth and you'll get nicotine quickly.
