Nic salts have become one of the most popular e-liquids in the UK, especially with the surge of disposable vape devices. Many vapers are moving away from traditional 50/50 freebase e-liquids to enjoy the smoother throat hit and faster nicotine satisfaction that nic salts provide.
But with strengths ranging from 5mg, 10mg, to 20mg, choosing the right nicotine strength can feel confusing - especially if you’re transitioning from smoking. Your ideal nic salt strength depends on your smoking history, how often you vape, and the type of device you use.
In this guide, we break down nicotine strengths, throat hit, flavour clarity, and vaping experience to help you find the best nic salt for your needs in the UK.
Nic Salt Strengths Explained: 5mg, 10mg, 20mg
Nicotine strength affects several aspects of your vaping experience:
Flavour intensity
Vapour texture
Throat hit
Frequency of vaping
Choosing the correct strength can make the difference between a smooth transition from cigarettes and an unsatisfying experience that leads to cravings.
Under UK TPD regulations, the maximum legal nic salt strength is 20mg. But the strongest option isn’t always the best.
20mg Nic Salts – Maximum Strength (High Dose)
Quick guide:
Maximum legal limit in the UK
Ideal for 10–20 cigarettes per day
Fast craving control
Perfect for heavy smokers quitting
Matches strength of most disposable vapes
Suitable for former 18mg freebase users
Why choose 20mg?
20mg (2%) nic salts deliver fast nicotine satisfaction for heavy smokers. Compared to high-strength freebase e-liquids (18mg), 20mg nic salts feel smoother on the throat thanks to benzoic acid. You need fewer puffs to satisfy cravings, making it cost-effective.
Who should use 20mg?
Heavy smokers (10–20 cigarettes per day)
Former disposable vape users transitioning to refillable kits
Vapers needing rapid craving relief
MTL vapers using low-power pod or pen kits
Anyone who finds high-strength freebase e-liquids harsh
Tip: If you feel lightheaded, dizzy, or nauseous, your nicotine might be too strong - reduce your strength to 10mg.

Quick guide:
Ideal for 5–10 cigarettes per day
Flexible option for step-up/step-down strategies

Why choose 10mg?
10mg (1%) nic salts are perfect for moderate smokers or vapers stepping down from 20mg. They offer a smooth vaping experience with excellent flavour delivery. Cravings are satisfied without producing overwhelming nicotine spikes.
Who should use 10mg?
Medium smokers (5–10 cigarettes per day)
Former disposable users who found 20mg too strong
All-day vapers wanting more frequent sessions

Should you start high and reduce?
For heavy smokers, yes. Start at 20mg, then step down gradually to 10mg or 5mg as cravings decrease.
