Nicotine Base (Shots & Salts): What They Are & How They Work
Nicotine base products—often referred to as nicotine shots or nicotine salts—are concentrated nicotine solutions used in DIY e-liquid mixing. They are added to nicotine-free base liquids and flavour concentrates to create a finished e-liquid with a specific nicotine strength.
This guide explains what nicotine base products are, the difference between freebase nicotine and nicotine salts, how they are used in mixing, and what users typically consider when working with nicotine formulations.
What Are Nicotine Base Shots?
Nicotine shots are small bottles of concentrated nicotine in a diluted base (usually VG, PG, or a blend). They are designed to be mixed into larger bottles of nicotine-free e-liquid.
They are commonly used for:
- DIY e-liquid mixing
- Increasing nicotine strength in shortfill liquids
- Customising nicotine levels
- Creating balanced VG/PG formulations
Nicotine shots are not intended for direct use and must always be diluted.
What Are Nicotine Salts?
Nicotine salts are a modified form of nicotine that is chemically combined with an acid to create a smoother inhalation experience at higher strengths.
They are commonly used in:
- Low-wattage devices
- Pod systems
- Mouth-to-lung (MTL) setups
- Nicotine-focused e-liquids
Nicotine salts differ from traditional freebase nicotine in how they are absorbed and how they feel during use.
How Nicotine Base Products Work in DIY Mixing
Nicotine shots and salts are added to nicotine-free e-liquid bases to achieve a desired strength.
Basic process:
- Start with a nicotine-free base liquid (VG/PG or shortfill)
- Add measured nicotine shot or nicotine salt solution
- Add flavour concentrates (if DIY mixing)
- Shake thoroughly to mix
- Allow time for the mixture to settle
The final nicotine strength depends on the amount of nicotine base added and the total volume of liquid.
Types of Nicotine Base Products
Nicotine base products come in different formats depending on formulation and intended use.
1. Freebase Nicotine Shots
Freebase nicotine is the traditional form used in most DIY mixing.
Features:
- Standard nicotine formulation
- Stronger throat hit at higher strengths
- Commonly used in sub-ohm or general e-liquids
- Available in VG, PG, or blended bases
Best For:
- DIY e-liquid mixing
- Users preferring traditional nicotine delivery
2. Nicotine Salt Shots
Nicotine salt solutions are designed for smoother nicotine delivery.
Features:
- Smoother inhalation at higher strengths
- Faster nicotine absorption profile
- Commonly used in pod-style devices
- Typically lower harshness compared to freebase
Best For:
- Low-power devices
- Mouth-to-lung vaping setups
- Users preferring smoother nicotine experience
3. VG-Based Nicotine Shots
VG-heavy nicotine shots are designed for thicker e-liquid blends.
Features:
- Higher VG content
- Smoother vapour production
- Better suited for sub-ohm blends
- Thicker liquid consistency
Best For:
- High-VG e-liquid recipes
- Cloud-focused vaping styles
4. PG-Based Nicotine Shots
PG-based nicotine shots are thinner and carry flavour more effectively.
Features:
- Thinner liquid consistency
- Stronger flavour delivery
- Easier mixing into shortfills
- Common in standard DIY recipes
Best For:
- Flavour-focused mixing
- Balanced VG/PG formulations
Key Differences: Freebase vs Nicotine Salts
Understanding the difference helps with selecting the right nicotine base.
Freebase Nicotine:
- Stronger throat hit
- Slower absorption
- Common in DIY mixing
- Works well in sub-ohm devices
Nicotine Salts:
- Smoother inhale
- Faster nicotine delivery
- Used in low-wattage devices
- Often preferred for higher nicotine strengths
How Nicotine Strength Is Calculated
Nicotine strength is determined by dilution ratio.
Factors include:
- Strength of nicotine base (e.g., mg/ml)
- Total liquid volume
- Amount of nicotine shot added
Accurate measurement is important for consistency in DIY mixing.
Storage & Handling
Nicotine base products should be handled and stored carefully.
- Store in a cool, dry place
- Keep away from sunlight and heat
- Ensure bottles are tightly sealed
- Store out of reach of children and pets
- Use protective handling practices when mixing
Safety Considerations
Nicotine is a concentrated substance and should always be handled with care:
- Do not use undiluted nicotine directly
- Avoid skin contact where possible
- Use proper measuring tools
- Work in a clean, controlled environment
- Follow dilution instructions carefully
Considerations Before Using Nicotine Bases
When working with nicotine shots or salts, users typically consider:
- Desired nicotine strength
- Device type (pod system vs sub-ohm)
- Freebase vs salt nicotine preference
- VG/PG ratio of final mix
- Flavour compatibility
- Mixing accuracy
Final Thoughts on Nicotine Base (Shots & Salts)
Nicotine base products are a core component of DIY e-liquid mixing, allowing users to adjust nicotine strength in a controlled and customizable way. Available in freebase and nicotine salt formats, as well as VG- and PG-based blends, they support a wide range of mixing styles and device preferences.
Understanding how nicotine shots and salts work, how strength is calculated, and how they differ helps create more consistent and informed DIY e-liquid formulations.
