Nic Salt vs Freebase Nicotine — Which Is Right for You?
Share
One of the most common questions we get asked is: what's the difference between nic salts and freebase nicotine? If you're new to vaping or switching devices, choosing the wrong type can make vaping feel harsh, unsatisfying, or just wrong. This guide explains everything clearly.
What Is Freebase Nicotine?
Freebase nicotine is the purest form of nicotine — processed to remove impurities, leaving nicotine in its 'free base' state. It's been the standard form of nicotine used in e-liquids since vaping began.
Freebase nicotine is effective but has a drawback at higher strengths: it becomes very harsh on the throat. This is why most freebase e-liquids are sold at 3mg, 6mg, or 12mg.
Common freebase formats:
- 50ml shortfill e-liquids (0mg, mix with a nic shot)
- 100ml shortfill e-liquids (0mg, mix with nic shots)
- 10ml TPD e-liquids (3mg, 6mg, 12mg, 18mg)
What Are Nic Salts?
Nic salts (nicotine salts) occur naturally in tobacco leaves. By adding a mild acid (usually benzoic acid) to freebase nicotine, the result absorbs into the bloodstream much faster and is much smoother at higher strengths.
This means nic salts can be vaped at 10mg and 20mg without the harsh throat hit you'd get from equivalent freebase strengths. The fast absorption means you get nicotine satisfaction quickly — similar to a cigarette.
Nic Salt vs Freebase — Side-by-Side Comparison
| Feature | Nic Salts | Freebase |
|---|---|---|
| Nicotine strength | 10mg, 20mg | 3mg, 6mg, 12mg, 18mg |
| Throat hit | Smooth | Stronger at higher mg |
| Nicotine absorption speed | Fast (like a cigarette) | Slower |
| Best device type | Pod kits, MTL devices | Sub-ohm, DTL devices |
| Cloud production | Lower | Higher |
| Best for | Smokers switching, beginners | Experienced vapers, cloud chasers |
Which Should You Choose?
Choose nic salts if you are:
- A smoker trying to quit or cut down
- New to vaping
- Using a pod kit or MTL device
- Looking for fast nicotine satisfaction
- Someone who finds freebase too harsh
Choose freebase if you are:
- An experienced vaper using a sub-ohm or DTL device
- Someone who enjoys big clouds
- Looking for lower nicotine (3mg–6mg)
- Mixing shortfills with nic shots
What About Shortfills?
Shortfill e-liquids (50ml or 100ml) contain zero nicotine. To add nicotine, you add a separate nicotine shot — typically an 18mg freebase 10ml shot. Adding one nic shot to a 50ml shortfill gives you roughly 3mg nicotine. Shortfills are the most cost-effective way to vape on a sub-ohm device — 100ml of premium e-liquid from £3.49 plus a 49p nic shot.
Frequently Asked Questions
Are nic salts safe?
Nic salts have been widely used in UK e-liquids since around 2017 and are considered as safe as other forms of nicotine used in vaping. All UK nic salt products must be TPD-registered and meet strict MHRA standards.
Can I use nic salts in a sub-ohm device?
We strongly advise against it. Using 20mg nic salts in a high-powered sub-ohm device can deliver an uncomfortably high dose of nicotine very quickly. Nic salts are designed for low-power, high-resistance MTL devices.
Which nic salt strength should I start with?
If you're a heavy smoker (20+ cigarettes/day), start with 20mg. Light smokers should try 10mg first.
