Nicotine strength guide: which mg is right for you

The right nicotine strength depends mostly on how heavily you used to smoke. As general guidance, many heavier previous smokers find 18mg to 20mg nic salt suits them, while lighter use often pairs better with 3mg to 12mg. The UK caps strength at 20mg per ml. None of this is medical advice, so treat the numbers as a starting point and adjust to your own comfort.

We sell prefilled pods and nic salts every day, so the strength question lands in our inbox constantly. This guide explains what the mg number actually means, how nic salts feel different to freebase, and how to step down once you have settled.

 

 

What does the mg number actually mean?

The strength printed on an e liquid is the amount of nicotine in milligrams per millilitre, written as mg per ml or sometimes as a percentage. A 20mg per ml liquid is the same as 2 percent. A 10mg per ml liquid is 1 percent.

A higher number does not mean more vapour or more flavour. It only means more nicotine per puff. Pick too high and you may feel lightheaded or get a harsh throat. Pick too low and you may chain vape trying to feel satisfied.

 

Nic salts versus freebase: how they feel

This matters as much as the number. Freebase nicotine is the older form. At higher strengths it gives a sharp, scratchy throat hit that many people find too aggressive above about 6mg.

Nicotine salt, often shortened to nic salt, is smoother. It lets you vape higher strengths like 18mg or 20mg without the harshness, and the body absorbs it faster, so a quick draw feels more satisfying. That is why nic salts in the UK have become the default choice for prefilled pods.

 

Matching strength to your previous smoking level

There is no exact conversion between cigarettes and nicotine strength, because everyone inhales differently and devices vary. The table below is general guidance only, not a medical recommendation. Start in the suggested range, then move up or down based on how you feel.

Is 20mg nicotine a lot?

Twenty milligrams per millilitre is the strongest you can legally buy in the UK under the Tobacco and Related Products Regulations 2016. It is designed for heavier previous smokers.

In a smooth nic salt pod, 20mg can feel comfortable and satisfying. The same 20mg in a freebase liquid would feel harsh and is rarely sold that high for exactly that reason. So the answer depends on the form as much as the number.

 

 

How to lower your nicotine strength over time

Many people like to reduce their strength once vaping feels routine. There is no rush and no fixed timetable. The aim is to keep it comfortable so you do not end up vaping more often to compensate.

• Drop one step at a time, for example 20mg to 12mg, rather than a big jump.
  
  
• Stay at each new level for a couple of weeks before deciding.
  
  
• If you find yourself vaping far more often, you have probably dropped too fast.
  
  
• Keep the flavour you like the same, so only one thing changes at once.
  
  
• Listen to your own comfort rather than chasing a target number.

 

Signs you have picked the wrong strength

Your body gives clear feedback. A strength that is too high can cause a sore throat, a slightly dizzy feeling, or mild nausea soon after vaping. Step down if that happens.

A strength that is too low usually shows up as constant puffing without ever feeling settled. If you are vaping non stop and still reaching for it, a slightly higher nic salt may suit you better.

 

Why strength matters more than you think

Getting the strength right is the difference between settling quickly and chopping back to old habits. Too weak and the draw never satisfies, so you reach for it constantly. Too strong and the harshness can put you off entirely.

When the strength fits, vaping feels calm and you forget about it between draws. That is the sweet spot worth aiming for, and it is why we spend so long helping people find their number rather than just selling the strongest pod on the shelf.

 

Where prefilled pods fit in

Prefilled pods take the guesswork out of mixing. The strength is clearly labelled, the 2ml pod meets UK limits, and you simply pick the mg that matches your range. Swap to a different strength next time if you want to fine tune.

Most of our pod ranges come in several strengths of the same flavour, so you can step down without giving up the taste you have got used to.

 

 

Compliance and safety

Nicotine strength choice is personal and the figures here are general guidance, not medical advice. Everything we stock is notified to the MHRA and made to TPD and TRPR standards, with 2ml pods, a 20mg per ml nicotine ceiling, and the required health warnings. We operate age verified checkout and UK based dispatch. For official guidance you can read GOV.UK vaping pages or contact Trading Standards and the Chartered Trading Standards Institute.

 

Frequently asked questions

1. Which nicotine strength should I choose?
   It depends mainly on how heavily you used to smoke. As general guidance, many heavier previous smokers find 18mg to 20mg nic salt suits them, while lighter use often pairs with 3mg to 12mg. This is not medical advice, so start in a sensible range and adjust to your own comfort.
   
   
2. What mg nic salt is right for ex smokers?
   As a common reference point, people who previously smoked around a pack a day often begin on 18mg to 20mg nic salt. Lighter previous smokers tend to start nearer 10mg to 12mg. Treat these as general guidance, then move up or down based on how satisfied you feel.
   
   
3. Is 20mg nicotine a lot?
   Twenty milligrams per millilitre is the legal maximum for sale in the UK under TRPR 2016, aimed at heavier previous smokers. In a smooth nic salt pod it can feel comfortable. The same strength in a freebase liquid would feel much harsher, which is why form matters as much as number.
   
   
4. Should I pick 10mg or 20mg nic salt?
   If you were a heavier smoker and want a satisfying draw, 20mg nic salt may suit you. If you were a lighter smoker, or you find 20mg too strong on the throat, 10mg is a gentler option. Many people start higher and then step down to 10mg over time.
   
   
5. What is the difference between nic salt and freebase?
   Freebase is the older form and feels sharp on the throat at higher strengths. Nic salt is smoother and absorbs faster, so you can vape stronger liquids like 18mg or 20mg without harshness. Most UK prefilled pods use nic salt for that reason.
   
   
6. How do I lower my nicotine strength?
   Step down gradually, one level at a time, and stay there for a couple of weeks before dropping again. Keep your usual flavour so only the strength changes. If you start vaping far more often, you have likely dropped too fast and can step back up.
   
   
7. How many mg of nicotine should I vape per day?
   There is no fixed daily figure, because devices and vaping styles differ widely. The better measure is comfort. If you feel settled and are not constantly puffing, your strength is working. If you feel jittery or harsh, step the strength down.
   
   
8. Can I buy stronger than 20mg in the UK?
   No. UK law caps consumer nicotine e liquid at 20mg per ml under the Tobacco and Related Products Regulations 2016. Any product offered above that strength is not compliant for sale in the UK, so always buy from a retailer that respects the limit.
