Nicotine Strengths Explained: How to Choose the Right One When You Switch

⏱ Estimated read time: 7–8 minutes • UK focus

Quick summary.

Match your nicotine strength to your current smoking habit, start with nicotine salts for a smoother hit if you’re new to vaping, then step down gradually. UK law caps nicotine at 20 mg/ml in retail e-liquids. If your vape feels too weak or too harsh, you’re likely on the wrong strength.

Available strengths: 5 mg • 10 mg • 20 mg

Choosing the right nicotine level is the difference between “that did nothing” and “that hit like a truck.” This guide makes it simple, with a clear table and flavour picks so you can start in the right zone and adjust from there.

Why nicotine strength matters

  • Too low: you’ll crave cigarettes because the vape isn’t satisfying.
  • Too high: harsh throat hit, dizziness, or nausea.
  • Just right: smooth inhale, cravings handled, no slip-ups.
UK rule of thumb: Shop e-liquids are legally limited to 20 mg/ml nicotine or less.

Quick guide: match strength to your habit

Your cigarette habit Suggested nicotine strength What it feels like
1–5 per day or social smoking 5–10 mg/ml (salts or freebase) Light, gentle. You may need a few extra puffs at first.
6–15 per day 10–12 mg/ml (salts preferred) Balanced. Good for most switchers on pod kits.
16–20 per day 18–20 mg/ml (salts) Stronger and smoother than freebase at the same level.
20+ per day 20 mg/ml (salts) to start, then step down Maximum legal retail strength in the UK; aim to reduce within weeks.

If a level feels too strong or too weak after a day or two, move one step up or down.

Nicotine salts vs freebase (plain English)

  • Nicotine salts: smoother inhale at higher strengths, quick craving relief, ideal for pod kits and new switchers.
  • Freebase nicotine: more throat hit, often used at lower strengths, good for lighter smokers or stepping down.
  • Devices: Pod kits and tight draws work best with salts. Big, cloudy devices suit low-strength freebase.

How to reduce strength over time

  • Start at the strength that stops cravings and replaces cigarettes fully.
  • After 2–4 weeks, drop to the next lower strength.
  • If cravings spike, mix half-and-half bottles for a week to land in between, then step down again.
  • Watch your triggers — coffee, stress, evenings — and adjust accordingly.

Example flavours at different strengths

Same flavour, different strengths. All available in 5 mg • 10 mg • 20 mg so you can fine-tune your switch.

Heads up: If you don’t smoke, don’t start vaping. This guide is for adult smokers switching to a less harmful alternative.

Quick FAQ

Is higher nicotine always harsher?
Not with nicotine salts. They’re designed to feel smoother even at higher strengths.

Can I use 20 mg/ml in a big cloud-chasing device?
No. High strengths are for small pod kits and tight draws. Using them in sub-ohm tanks can deliver too much nicotine.

What if I feel light-headed or nauseous?
That’s usually too much nicotine. Step down a level and take fewer puffs.

What if I’m still craving cigarettes?
Try one step higher, or take a couple more puffs. Check your pod or coil is fresh too.
