Hi Nnya! Thanks for jumping into the topic, and I’m rooting for your Vaperstore order to arrive somehow! 
Your question about boosters and salts (nicotine salt) is absolutely valid, because the terminology can sometimes be quite confusing, especially when someone is suddenly switching to mixing.
Let’s get to the main points, and then we’ll address the questions about tobacco shops! 
Booster vs. Nicotine Salt – The Difference
The main point is that booster and nicotine salt are not the same, but salt can be present in the booster!
- Nicotine Booster: This is the umbrella term. It’s a 10 ml liquid that can contain a maximum of 20 mg/ml nicotine, and it’s used to mix your nicotine-free base liquid or aroma to your desired strength.
- Nicotine Salt: This is the type of nicotine.
What is the difference between the two nicotine types?
| Type | Characteristic | Who is it recommended for? |
|---|---|---|
| Freebase Nicotine | Stronger throat hit, slower absorption. This is the “traditional” nicotine. | For those who like to feel the throat hit, or vape at lower nicotine levels. |
| Nicotine Salt (Salt) | Much smoother throat hit, faster absorption, higher pH. | For those who want to vape at higher nicotine levels (e.g., above 12 mg/ml) without throat irritation. |
In summary: If a booster says “Salt” or “Nicotine Salt”, it contains nicotine salt. If it says nothing, it usually contains freebase nicotine. Since you’ve been vaping pre-mixed liquids at 12-18 mg/ml so far, the traditional (freebase) booster will likely be the closest to your previous experience.
