Nicotine Salts vs Freebase Nicotine: What Should I Vape?
Are you a smoker thinking about switching to vaping? Or maybe you’ve tried vaping but didn’t get the nicotine hit you expected. The main factor that affects satisfaction is the type of nicotine you choose.
There are two types: nicotine salts and freebase nicotine. This guide will help you understand the differences, determine which to vape, and choose the right device for your style and budget.
What Is Freebase Nicotine?
Freebase nicotine is the classic form of nicotine, the same type found in tobacco and cigarettes. It’s the pure, unbound form that was used in early E-Liquids because it was straightforward to produce and a natural transition for smokers.
Key point: Popular with vapers who want flexibility in flavours, strengths, and cloud production.

What Is Nicotine Salt?
Nicotine salts are nicotine molecules naturally bound to acids, as they exist in tobacco leaves. While identified in the 1960s, they weren’t widely used in vaping until pod-style devices became popular in the mid-2010s.
Key point: Salts allow higher nicotine strengths with minimal harshness, making them ideal for smokers switching to vaping.

Quick Comparison: Nicotine Salts vs Freebase
| Feature | S Nicotine Salts | F Freebase Nicotine |
|---|---|---|
| Nicotine delivery | Faster, more cigarette-like | Slower, more gradual |
| Typical strengths | 10–20mg | 3–12mg |
| Throat hit | Smooth at higher strengths | Stronger as strength increases |
| Vapour production | Lower | Medium to high |
| Best for | Switching from smoking, quick satisfaction | Lower strengths, longer vaping sessions |
| Common formats | Prefilled pods, 10ml bottles | 10ml bottles, shortfills + nic shots |
| Ease of use | Very simple | Can require some setup |
Key takeaway: Nicotine salts deliver nicotine faster, giving a quicker hit like a cigarette. Freebase takes longer but allows more control over strength, flavours, and clouds.
Recommended Nicotine Strengths for Each Type
You can estimate your starting strength based on how many cigarettes you smoke per day:
| Cigarettes per Day | S Nicotine Salts | F Freebase Nicotine |
|---|---|---|
| 0–10 | 10mg | 3–6mg |
| 10–20 | 10–20mg | 6–12mg |
| 20+ | 20mg | 12+mg |
Keep in mind: These are just guidelines. What really matters is how satisfied you feel when vaping.
What Nicotine Type Should Beginners Vape?
If you’re new to vaping or switching from smoking, here are the best setups for each nicotine type:
Nicotine Salts
- Use a prefilled pod device for a quick, ready-to-go experience.
- Minimal setup, insert pod and vape.
Freebase Nicotine
- Can be used by beginners, but needs a refillable pod device + refillable pods + 10ml 50/50 E-Liquid.
- Slightly more prep required, but allows flexibility in strength and flavours.
Summary
- Easiest route: nicotine salts + prefilled pod.
- Alternative: freebase E-Liquid + refillable pods.
Tip: Avoid mods and sub-ohm kits to begin with; they have a steep learning curve for beginners.
How Does Vaping Style Affect Nicotine Salt & Freebase?
Your vaping style has a direct effect on what nicotine type you should vape:
Mouth-to-Lung (MTL)
With mouth-to-lung, each puff produces much less vapour, and inhalation is slower and more controlled. This means:
- Higher nicotine strengths are needed to achieve satisfaction
- Nicotine salts work well because they provide smooth nicotine delivery at higher strengths
- Moderate-strength freebase remains comfortable because the vapour volume per puff is low
Direct-to-Lung (DTL)
With direct-to-lung, you inhale a large volume of vapour in one breath. Because freebase nicotine delivers nicotine more slowly than salts, using it at lower strengths allows users to:
- Avoid taking in too much nicotine at once
- Prevent a harsh throat hit caused by high nicotine × high vapour volume
- Maintain control over nicotine intake during longer, deeper inhales
At higher strengths, freebase combined with DTL would feel excessively harsh and deliver more nicotine than intended in a single inhale.
Ask yourself what kind of vape you want:
DTL: more vapour → lower-strength freebase nicotine
MTL: less vapour → higher-strength nicotine salts
How Does Device Type Affect Nicotine Salt & Freebase
Prefilled Vape Devices
Low-power, MTL devices that produce small vapour volumes. Work with nicotine salts because they deliver smooth nicotine at higher strengths. Freebase isn’t used here, as it would feel harsh at MTL strengths.
Refillable Pod Kits
Moderate power, flexible airflow. Can use nicotine salts or freebase, as vapour output can match the nicotine type and inhalation style.
Sub-Ohm Tanks/Mods
High-power, DTL devices producing large vapour volumes. Only freebase is suitable; nicotine salts deliver too much nicotine too quickly and would be harsh.

Is Freebase or Nicotine Salts More Expensive?
Freebase and nicotine salts have different cost considerations. See how they compare in this table:
| Device Type | Average Setup Price | What You Need | Nicotine Type |
|---|---|---|---|
| Prefilled Pod Kit | £5–£15 | Reusable device + prefilled pods | Nicotine salts |
| Refillable Pod Kit | £10–£30 | Reusable device + refillable pods + bottled E-Liquid | Nicotine salts or freebase |
| Sub-Ohm Tank/Mod | £20–£50 | Device + coils, tanks, batteries, bottled E-Liquid | Freebase nicotine |
Quick insight:
- Lower cost: prefilled nicotine salt pods with a reusable device provide the cheapest, most convenient option
- Medium cost: 10ml E-Liquid bottles in freebase or nicotine salt with a refillable device still offer great value for money.
- Higher cost: shortfills + freebase nicotine shots with high-powered kits, more flexibility and cloud production, but are more expensive upfront.
Other factors affect cost, including ongoing cost and vaping frequency. Read our Guide to Vaping Costs in 2026 to learn more.
What IVG Products Should I Try for Each Type?
There are several IVG products you can try in nicotine salts and freebase:
Nicotine Salts
- Intense Salts: bottled E-Liquids designed for a smooth vaping experience with maximum flavour and less harsh throat hits.
- Prefilled Vape Kits: Prefilled nicotine salt pods and reusable vape devices, ideal for people who value convenience and flavour.
Freebase Nicotine
- 50/50 Original: bottled E-Liquids designed to replicate the sharper throat hit of smoking in classic IVG flavours.
- Shortfills: nicotine-free E-Liquid designed to be used for DTL vaping.
How the 2026 UK Vape Tax Affects Freebase & Nicotine Salts
The new Vape Tax can impact your costs differently depending on the type of nicotine you vape. Here’s a simple breakdown with examples:
| Nicotine type | F Freebase Nicotine Shots | F Freebase Premixed E-Liquid | S Nicotine Salts |
|---|---|---|---|
| How it’s used | Mixed with nicotine-free E-Liquid (e.g. 100ml) | Ready to vape (e.g. 10ml bottle) | Premixed bottles or prefilled pods |
| Tax rate | £0.22 per ml | £0.22 per ml | £0.22 per ml |
| What’s taxed | Both the nicotine shot and the full mixed bottle | Only the bottle you buy | Only the bottle or pod you buy |
| Example volume | 20ml shot + 100ml E-Liquid (120ml total) | 10ml bottle | 22ml pod |
| Example tax cost | £26.40 | £2.20 | £4.84 |
Key Takeaway:
- Freebase nicotine shots are hit hardest because tax is applied to both the shot and the large bottle it’s mixed into.
- Premixed nicotine salt and freebase E-Liquid are taxed only on the E-Liquid you buy, so the total tax is much lower.

FAQs
Can I mix freebase and nicotine salts? No, they vape differently, so mixing can give an unpleasant hit or damage your device.
Is one healthier than the other? Neither is risk-free. Both contain nicotine, but are generally considered safer than smoking.
