How Much Nicotine Is In A Lost Mary
Nicotine in a
Lost Mary?
20mg per millilitre is the UK legal maximum. That means 40mg total in a 2ml Lost Mary pod. Here is the full breakdown covering all four strengths plus how to pick the right starting level.
Most Lost Mary products contain 20mg of nicotine per millilitre which is the UK legal maximum. A full 2ml pod therefore contains 40mg of total nicotine. Lower strength Lost Mary nic salt refills are also available at 10mg, 5mg and 3mg for step-down users or lighter smokers. Any Lost Mary product claiming more than 20mg per ml is not UK-legal retail stock.
UK nicotine law and
what Lost Mary delivers
Three numbers that cover the UK legal ceiling, the total nicotine in a full pod plus the range of strengths available.
UK legal max
The Tobacco and Related Products Regulations 2016 cap nicotine strength at 20mg per ml for every e-liquid.
Per 2ml pod
A 2ml Lost Mary pod at 20mg nic salt contains 40mg of total nicotine. The UK legal maximum per single pod.
Lost Mary range
Lost Mary nic salt refills come in 20mg, 10mg, 5mg plus 3mg to suit different user intensities.
Maximum 20mg per ml. Four strengths. One regulatory ceiling.
Nicotine strength is the one number to get right when switching from smoking to Lost Mary. Most Lost Mary products are sold at the UK legal maximum of 20mg per ml. Lower strengths are available for lighter users or for ex-smokers who have been on Lost Mary for a few months and are ready to step down. Here is the full breakdown plus how to match strength to your starting habit.
The UK 20mg legal cap
Every vape product sold in the UK is subject to the Tobacco and Related Products Regulations 2016. These cap nicotine strength at 20mg per millilitre for any e-liquid. The cap applies to pre-filled pods, refill bottles plus nic salt formulations. It applies to the original Lost Mary disposable from before the June 2025 ban. It applies to every post-ban Tappo pod plus every BM6000 refill.
The 20mg ceiling was set by UK regulators to match the daily nicotine intake of a typical pack-a-day smoker while avoiding medically meaningful toxicity levels. A 2ml pod at 20mg delivers 40mg of total nicotine which is broadly equivalent to 20 cigarettes worth.
The four Lost Mary nic salt strengths
The BM6000 refill kit accepts any TPD-compliant 10ml nic salt bottle. Lost Mary branded refill liquids come in four main strengths.
- 20mg per ml. The UK legal maximum. Starting strength for heavy 20-a-day smokers.
- 10mg per ml. Suited to light-to-moderate smokers on 10 a day or less. Also the first step-down strength for ex-smokers after month one.
- 5mg per ml. A mid-step strength used after the first few months.
- 3mg per ml. Late-stage quit strength. The lowest nic salt strength available.
Nicotine per puff
A 2ml 20mg Lost Mary pod delivers approximately 600 puffs. Dividing 40mg by 600 gives roughly 0.067mg of nicotine per puff. The body absorbs a fraction of this depending on draw length plus exhale pattern. Average absorption sits at 50 to 75 per cent. This is why a 20mg pod can satisfy a 20-a-day smoker for a full day.
How to pick the right strength
- 20 a day or more smoker. Start at 20mg. Anything lower risks chain-vaping plus relapse in week one.
- 10 a day smoker. Start at 10mg. Upgrade to 20mg if cravings are not satisfied inside the first three days.
- 5 a day or social smoker. Start at 5mg.
- Ex-smoker stepping down. Move one tier down only. 20 to 10. 10 to 5. 5 to 3.

Four strengths, one UK
legal maximum ceiling
Lost Mary nic salt refills span four strengths from the UK legal maximum down to the minimum before zero. Here is what each one delivers.
Heavy smoker
UK legal max. A 2ml pod carries 40mg total. Roughly 20 cigarettes equivalent. Start here for 20-a-day or more smoking.
Moderate smoker
Half strength. 20mg total per pod. Roughly 10 cigarettes equivalent. Suited to 10-a-day smokers or first step-down.
Step-down
Quarter strength. 10mg total per pod. Roughly 5 cigarettes equivalent. Mid-journey step for ex-smokers.
Late stage
Lowest nic salt strength. 6mg total per pod. Roughly 3 cigarettes equivalent. Optional long-term harm-reduction strength.
What to know
before you pick a strength
20mg per ml is the UK legal maximum
TPD 2016 caps e-liquid nicotine at this level for every brand plus format sold in the UK.
40mg total per full 2ml pod
Multiplying 2ml by 20mg per ml gives the total nicotine content of a full Lost Mary pod at maximum strength.
Step down over months not days
Most ex-smokers stay on 20mg for one to three months before stepping down. Let the body set the pace.
Above 20mg means non-compliant
Any Lost Mary branded product claiming more than 20mg per ml is not UK-legal retail stock.
