The detail

10mg vs 20mg JUST SALTS: how to choose

The two strengths look almost identical on the bottle but they behave quite differently in real use. 20mg JUST SALTS is at the UK legal maximum and is designed to replace cigarettes for adults who previously smoked heavily. 10mg JUST SALTS is the maintenance strength, used either by people who smoked moderately or by ex-smokers who have been stable on 20mg for a few months and want to start reducing.

The single most common mistake we see at the counter in Omagh and Strabane is the heavy smoker who picks 10mg because they are wary of high nicotine. The result is almost always chain-vaping, never quite feeling satisfied and slipping back to cigarettes within a week or two. Cigarettes deliver roughly 1 to 2mg of absorbed nicotine each, and a 20-a-day smoker is genuinely used to a meaningful nicotine intake. Starting too low does not protect you, it just means the switch fails.

The second most common mistake is sticking on 20mg forever. Once your switch is stable and cravings have settled, dropping to 10mg makes the bottle last longer, gives slightly cleaner flavour and is the natural next step on a measured reduction path. There is no rush, but there is no benefit to staying at the legal maximum once you no longer need it.

The chemistry that makes 20mg smooth

20mg of freebase nicotine in a 10ml bottle would be harsh enough that most ex-smokers cough on the first puff. The reason JUST SALTS 20mg is smooth is the salt chemistry. Nicotine combined with a mild organic acid (commonly benzoic acid) lowers the pH of the e-liquid, and that small change is what takes the throat-hit edge off a high-strength bottle. Same legal nicotine cap, completely different feel from old-style high-strength e-liquid.

Cigarettes per day as a starting guide

The cleanest way to choose your first JUST SALTS strength is by matching your previous cigarette intake. If you smoked 20+ a day, start at 20mg. If you smoked 10 to 20 a day, you can usually start at 10mg, though 20mg is fine as well if cravings feel strong. If you smoked under 10 a day, 10mg is almost always the right starting strength. You can always step up if a 10mg bottle leaves you puffing constantly, and step down if a 20mg bottle feels too intense. Our guide to switching from cigarettes walks through the journey week by week.

PICK 20MG IF

You smoked 20+ a day

Or you have just quit. Or cravings feel strong. 20mg gives full cigarette-strength nicotine and is what most successful switchers start on.

PICK 10MG IF

You smoked under 20 a day

Or you have been stable on 20mg for 3 months and want to step down. 10mg is the maintenance strength and lasts longer per bottle.

TOO HIGH SIGNS

Dizzy, jittery, mild nausea

Step down to 10mg or vape less often per session. None of these symptoms are dangerous in a one-off, but they signal the wrong strength for you.

TOO LOW SIGNS

Chain-vaping, cravings, finishing a bottle a day

Step up to 20mg. Under-dosing is the most common reason ex-smokers slip back to cigarettes in the first month.

Stepping down

When and how to drop from 20mg to 10mg

You do not need to stay on 20mg forever. Once your switch is settled, dropping to 10mg is the standard next step on a measured nicotine reduction path. Here is how to do it without setting yourself up to relapse.

1

Wait until you are stable

Three to six months on 20mg is the usual window. Wait until you can put the kit down between sessions, are not thinking about cigarettes and have stopped chain-vaping.

2

Alternate bottles for a week

Refill with 10mg in the morning and 20mg in the evening for a week. This lets your body settle to the lower dose gradually rather than going cold turkey on the high strength.

3

Switch fully when ready

Most people are comfortable on 10mg after a week of alternating. Move fully across when alternating feels routine and 10mg sessions feel satisfying.

4

Step back up if you slip

If cravings come back hard or you start thinking about cigarettes, go back to 20mg for another month or two. There is no shame in pausing the step-down.

FAQ

Frequently asked questions

Should I start on 10mg or 20mg JUST SALTS?
As a general rule: 20mg JUST SALTS suits adults who previously smoked around 20 cigarettes per day or more, 10mg suits 10 to 20 a day, and light or social smokers under 10 a day are often comfortable starting on 10mg. If you have just stopped smoking and cravings feel strong, 20mg is usually the safer starting point because under-dosing is the most common cause of relapse.
Is 20mg nic salt safe in the UK?
Yes. 20mg per ml (sometimes written as 2%) is the maximum legal strength for nicotine e-liquid in the UK under TPD regulations, and JUST SALTS 20mg sits at that legal cap. It is designed for heavy smokers transitioning to vaping and is only smooth at that strength because the acid in nic salts lowers the pH. The same dose in freebase e-liquid would be far too harsh.
How do I know if my JUST SALTS strength is too high?
Watch for dizziness, a faintly sore throat, mild nausea, headache or feeling jittery. Those are signs your strength is too high. The fix is to step down from 20mg to 10mg, vape less often per session, or both. None of these symptoms are dangerous in a one-off, but if they keep happening the strength is wrong for you.
How do I know if my JUST SALTS strength is too low?
If you are constantly puffing, chain-vaping, still thinking about cigarettes or finishing a 10ml bottle in a day, the strength is too low. Move up from 10mg to 20mg, especially in the first few weeks after quitting. Under-dosing is the most common reason switchers slip back to cigarettes.
When can I step down from 20mg to 10mg JUST SALTS?
Most people who switched from cigarettes are comfortable stepping down after roughly 3 to 6 months of stable 20mg use. The signs you are ready: you can put the kit down between sessions, you are not thinking about cigarettes, and you are no longer chain-vaping. Try alternating bottles for a week first to ease the change.
What pod kit do I need for 20mg JUST SALTS?
A 1.0 ohm or higher MTL (mouth-to-lung) pod kit running at around 10 to 15W. UK examples include the Aspire Pockex, Innokin Endura T22, OXVA Xlim Pro 2 and Vaporesso XROS 5. Avoid sub-ohm direct-to-lung tanks with 20mg salts because they vapourise too much e-liquid per puff and can deliver too much nicotine.
