Cigarette (factory-made): nicotine content
The 1 mg figure attached to cigarettes in EU law is a machine measurement of the smoke, not the nicotine in the tobacco and not the dose a person receives. All three numbers are different, and only the last one matters to a smoker.
This is a reference page about what is printed on packs and what EU law caps. It is not medical advice, not a diagnosis and not a recommendation to use any product here. Nicotine is addictive and every product on this page can sustain that dependence. If you use nicotine and want to stop, a pharmacist, a doctor or your national cessation service will help you more than a table will.
What the number on the pack is
| Item | Figure |
|---|---|
| Category | Burned or heated tobacco |
| The declared figure | Machine-measured nicotine in the smoke, in mg per cigarette |
| Legal position | EU: 1 mg nicotine, 10 mg tar, 10 mg carbon monoxide per cigarette |
| EU machine-yield ceiling | 1 mg nicotine per cigarette |
| Typical absorbed dose | about 1 to 1.5 mg per cigarette |
| Time to brain | about 10 to 20 seconds |
| Nicotine half-life | about 2 hours |
| Cotinine half-life | about 16 hours |
The 1 mg is a laboratory ceiling, not a dose
Article 3 of the Tobacco Products Directive sets maximum emission levels for cigarettes sold in the EU: 1 mg of nicotine, 10 mg of tar and 10 mg of carbon monoxide per cigarette. Those figures come from a smoking machine that draws a fixed puff volume on a fixed schedule under standard ISO conditions. A person does not smoke like that. Puff volume, puff frequency, how deeply the smoke is drawn and how long it is held all vary between smokers and within the same smoker across a day.
The gap is not a rounding error. Cigarette filters are perforated with ventilation holes that dilute the machine-drawn smoke with air. Fingers and lips cover a large share of those holes in real use, which raises the delivered dose well above the measured yield. This is why the current directive removed the old requirement to print tar, nicotine and carbon monoxide figures on the pack: printed yields were being read as a strength ranking, and they are not one. The pack now carries a general warning and an information message instead.
What is in the tobacco, and what reaches the smoker
The tobacco rod holds far more nicotine than the machine yield suggests. Most of it never reaches the smoker: it is destroyed by the burning coal, carried away in sidestream smoke between puffs, or trapped in the filter and the unsmoked butt. Pharmacokinetic studies of real smokers converge on roughly 1 to 1.5 mg of nicotine absorbed per cigarette, which is the number worth carrying to any comparison with another product.
A twenty-a-day smoker is therefore absorbing something in the region of 20 to 30 mg of nicotine a day. That is the figure to hold next to the declared content of a pouch or a bottle of e-liquid, and it is the reason a single number on a can tells you very little on its own.
Why a cigarette has to be inhaled
Nicotine is a weak base with a pKa near 8. In an acidic environment it is ionised and crosses membranes poorly; in an alkaline one it is un-ionised and crosses them easily. Smoke from flue-cured tobacco, which is what cigarettes are made of, is acidic. That means very little nicotine is absorbed through the lining of the mouth, and a cigarette only works if the smoke is drawn into the lungs.
Once it is, the alveolar surface is enormous and the blood supply is immediate. Nicotine reaches arterial blood within a second or two of the puff and the brain within roughly ten to twenty seconds. That speed, not the total dose, is what makes the cigarette the most reinforcing nicotine product ever sold: the interval between the action and the effect is short enough for the brain to bind them together tightly.
The shape of a smoking day
Nicotine has an elimination half-life of about two hours, so a smoker who smokes through the day never returns to baseline until the night. Levels accumulate through the morning, plateau, and fall overnight, which is why the first cigarette after waking is the one that produces the largest relative jump and why the time to that first cigarette is the strongest single question in standard dependence questionnaires.
Cotinine, the main metabolite, has a half-life near sixteen hours, which is why cotinine rather than nicotine is measured in saliva, blood and urine when someone needs to know whether a person has been using nicotine over recent days rather than in the past few hours.
Against a cigarette
The only figure that lets any of these formats be compared is what a smoker actually absorbs: roughly 1 to 1.5 mg of nicotine per cigarette, or something in the region of 20 to 30 mg across a twenty-a-day habit. That is a measured absorbed dose, and it is not the same kind of number as the one on most packs.
This is the format the comparison is anchored to, which is why the absorbed figure and the machine yield are printed side by side above.
| Reference point | Figure |
|---|---|
| Nicotine absorbed from one cigarette | about 1 to 1.5 mg |
| Nicotine absorbed at twenty cigarettes a day | about 20 to 30 mg |
| EU cigarette machine yield ceiling | 1 mg per cigarette |
| Nicotine in a full EU-legal single-use vape | up to 40 mg, as a content |
| Nicotine in a full 10 ml refill bottle at 20 mg/ml | 200 mg, as a content |
| Cigarette (factory-made) | Up to 1 mg machine yield; roughly 1 to 1.5 mg actually absorbed |
Quitting from here
The pattern that has the most evidence behind it is a long-acting patch to hold the baseline plus a fast-acting form for the moments a craving arrives, rather than either alone. Prescription options exist as well and are a conversation with a clinician, not a shelf decision.
The pattern with the most evidence behind it is the same whichever product you are stopping. A long-acting form holds the baseline so that withdrawal is not generating cravings all day, and a fast-acting form is there for the moments a craving still arrives. Cochrane reviews of nicotine replacement therapy find that using it improves the chance of stopping compared with no medication, and that combining a patch with a fast-acting form does better than either on its own. Behavioural support on top of medication does better again.
Two things are worth knowing before you start. Under-dosing is the usual failure: people choose the low strength, use it less often than the label says, and conclude that replacement does not work for them. And prescription medicines exist for tobacco dependence as well; those are a conversation with a clinician rather than a shelf decision.
National services are free and staffed by people who do this all day. In Estonia the National Institute for Health Development runs cessation counselling and publishes the current clinic and helpline list. In Finland the Stumppi service run by Filha covers the same ground. In Sweden it is Sluta-Roka-Linjen. Your pharmacy will know the local one.

Frequently asked questions
How much nicotine is in one cigarette?
The tobacco holds well over the 1 mg machine yield, most of which is burned or lost in sidestream smoke. A smoker absorbs roughly 1 to 1.5 mg per cigarette, which is the figure to use in any comparison.
Are lower-yield cigarettes weaker?
Not in practice. Smokers adjust puff volume, puff frequency and depth to reach a familiar nicotine level, and filter ventilation holes are partly covered by fingers and lips. The EU stopped requiring printed yields for exactly this reason.
How long does nicotine stay in your body after a cigarette?
Nicotine itself has a half-life of about two hours. Its metabolite cotinine lasts far longer, with a half-life near sixteen hours, which is what tests look for.

What changes when you stop
Sleep, resting heart rate, mood and appetite all move in the first weeks. TempoLife logs them in one place so the change is something you can see rather than something you have to remember.
