Nicotine delivery vs nicotine content: the distinction that matters

The milligram figure on a can tells you how much nicotine is inside the pouch, not how much will reach you — and the two are related without being proportional. Six independent laboratories have now weighed what is actually in these products, and most come in under their stated figure, one by more than half. No jurisdiction anywhere sets an accuracy requirement on that number, and the things that decide what you actually absorb — pH, the fleece, how the powder is packed — never appear on the label at all.

This is the single most useful idea in the whole category, and it is almost never stated plainly. Content is a property of the object. Delivery is a property of what happens in your mouth. Everything confusing about pouch strengths — why a 6 mg from one brand flattens you and another does nothing, why stepping up a tier sometimes changes nothing, why the number felt wrong — sits in the gap between those two things.

What the number on the can actually measures

It measures mass. Somewhere in the manufacturing process, a quantity of nicotine went into a quantity of filler, and the figure printed on the tin is the result of that arithmetic — or, in several cases, a target that the arithmetic was supposed to hit. It is a statement about the contents of a sealed object.

What it is not is a dose. A dose is what crosses the lining of your mouth in the twenty, thirty or sixty minutes the pouch spends under your lip, and that depends on how much of the nicotine leaves the powder, how much of what leaves is in the form that crosses a membrane, and how long you keep it in. All three of those are set by product design and by your own behaviour, and none of them is on the can. If you want the mechanics of the second part, our piece on nicotine pouch absorption covers the clocks involved; this one is about the first.

Before any of that, there is a prior question that turns out not to have a comfortable answer: is the number even right?

What happens when somebody weighs it

Six laboratories have measured the nicotine actually present in commercial pouches and compared it against the label. Their results do not all agree, which is itself informative.

Who measured	What	Measured against label
RIVM, Netherlands (2020-0152)	11 pouch products bought from Dutch webshops	64–91% — every one of the eleven below its declared figure
CDC Division of Laboratory Sciences (Tran, Stanfill et al.)	70 oral products, metro Atlanta	Pouches ran “from 45% below and 1% above the indicated strength”
Roswell Park (Page et al.)	61 products, 10 pouch brands	“most ONPs, measured nicotine content was consistent with values provided on packages (within 20%)”, with outliers at roughly −60% and −40%, and one tobacco product 20% above
Johns Hopkins / Portland State (Cohen et al.)	10 Velo variants, Karachi	80–95%: “the measured level was similar to, though always somewhat lower than, the labelled level”
BfR / German Federal Institute (Mallock-Ohnesorg et al.)	The 6, 20 and 30 mg products used in its own clinical study	“the pouches only contained between 80% and 90% of the declared nicotine content”
University of Maribor (Rantaša & Finšgar)	26 pouches on the Slovenian market	“The determined nicotine content in NPs deviated up to -52.9% from that declared by the manufacturers” — abstract only; the full text is paywalled and I could not open it

Read that table carefully, because the lazy summary of it is wrong. It does not show that labels are fiction. It shows that products usually contain somewhat less than they claim, occasionally a great deal less, and once in a while more. The CDC’s conclusion is the measured version of that: “The measured total nicotine content was either equal to or less than the level stated on the label, except for one product.”

Two caveats belong with it. RIVM flagged its own method: “De nicotinegehaltes zijn gescreend middels een niet-gevalideerde methode” — screened with a non-validated method — and noted that a validated one for these products still had to be developed. And Roswell Park found that an apparent shortfall can be an artefact of the chemistry rather than the label, reporting that for one brand “the measured nicotine released at 60 minutes was similar to the label, suggesting that methanol did not efficiently extract nicotine from this formulation”. The solvent could not get the nicotine out of the powder; the mouth could. That is a reason to be careful with any single dramatic number — including the one at the bottom of the table.

What survives all the caveats is the direction. Across six labs, four countries and well over a hundred products, the figure on the can is a ceiling far more often than a floor.

Why content does not set delivery

Now the more interesting half. Even where the label is accurate, it does not predict what you get — and the clearest evidence for that comes from people with no interest in making the point.

Roswell Park compared tobacco-free pouches against tobacco-containing ones and found this: “Although ONPs contained, on average, 50% less nicotine than OTPs (6.4 ± 3.5 vs. 12.3 ± 8.2 mg/pouch, p < .001), they released similar amounts of nicotine within 5 minutes (ONPs 6.5 ± 3.9 vs. OTPs 7.6 ± 3.9 mg/pouch, p = .422).” Half the content, the same nicotine out in five minutes. Their own summary: “Although nicotine content was significantly higher in OTPs than in ONPs, the amount of nicotine released from the pouch was very similar between ONPs and OTPs.”

The within-category spread is even starker. In the same study, “most pouches released >80% of total nicotine content within 5 minutes”, but “A delayed release was observed from Rogue pouches, where spearmint 6-mg pouches released 72.3% of their nicotine content and wintergreen 3-mg pouches released <1% at 5 minutes”, against another brand’s 8 mg releasing 90.8% in the same window. Under 1% versus 90.8%. Both of those are nicotine pouches. Both have a number on the tin.

And the point is conceded by the industry’s own chemists. Altria’s laboratory, publishing on its own on! products, concluded that “These data indicate that the total amount of nicotine content in on!® pouches does not affect the nicotine release profile”, attributing the differences it did find to “inherent product characteristics (e.g., pouch paper and ingredients)”. The company with the most to gain from a simple milligram ladder published a paper saying the milligrams do not set the release.

What does set it

Four things, none of them printed anywhere.

The form the nicotine is in. The CDC puts it plainly: “Freebase nicotine is the form of nicotine most readily absorbed across oral membranes and it varies depending on the pH levels of the products.” Raise a product’s pH and a larger share of the same nicotine becomes the kind that crosses a membrane. The CDC’s own data make the consequence concrete — one brand’s 8 mg pouch had roughly half the freebase percentage of its 2 and 4 mg siblings, so quadrupling the content did not quadruple the absorbable fraction. Our piece on pouch pH goes further into this.

The powder. How finely ground, how densely packed, how wet. These change how fast nicotine comes out of the filler and into saliva.

The bag. The FDA’s own chemist, in a 2016 Center for Tobacco Products memorandum, lists the pouch material as a design lever in its own right: “The permeability of the pouch material may affect the microenvironment within the pouch. Lower permeability may drive the conversion of nicotine to free nicotine.”

You. How long you keep it in, and where. The same memorandum notes that release “can be modified by a number of physiological factors, including salivary flow, salivary pH changes, oral enzymes and other factors”.

That memorandum is the most quotable single document on this subject, and its summary of the mechanism is better than anything I could write: “The rate of the nicotine release is controlled through a number of mechanisms, including addition of pH modifiers [2, 3], pouch materials [2, 3], casing and dressing components (such as fillers and binders) [4-6].” The reference markers are the FDA’s own. Not one of the levers in that sentence changes the milligram figure on the can. All of them change what reaches you. Why two 6 mg pouches from different brands feel completely different works through the product chemistry in detail.

The same FDA memo contains a sentence that should end any argument about how firm the underlying number is: “For tobacco products, both the amount of tobacco used in each measurement and the amount of nicotine present in the tobacco leaves are not known.” For a pharmaceutical, release is measured against a labelled value you can trust. For a tobacco product, FDA says, you have to establish the total yourself for every single run, because there is no reliable label to measure against. The memo carries FDA’s standard caveat that it is “not binding on FDA or the public”, and it is still the agency’s own chemist describing the problem.

The honest counterweight

It would be easy to take all this too far, so here is the evidence pointing the other way. An industry-independent human study at Virginia Commonwealth University gave 24 smokeless tobacco users 2, 4 and 8 mg pouches from a single brand and concluded that “labeled nicotine content influences the nicotine delivery and abstinence symptom suppression” of that product.

That is exactly what you would expect, and it matters. Within one brand, one formulation and one pH, the number does track delivery — more nicotine in the pouch really does mean more nicotine in you. The label is not noise. What it is not is portable: it tells you something real about the relationship between two products from the same maker, and much less than you think about the relationship between two products from different makers. BfR’s own researchers put the limit on it from the other direction, finding a “relative bioavailability ranging from 70% to 165%” across products and concluding that “The nicotine release rate varies across products and needs to be known to estimate the nicotine delivery.”

Four jurisdictions, four different units

Part of the confusion is that the world cannot agree what to print. I went through the instruments that actually exist:

• Denmark requires it per pouch, in terms: “Nikotinindhold pr. enhed. For nikotinposer er det pr. pose.” Omitting it is a criminal offence carrying a fine, with corporate liability attached.
• Czechia is the most prescriptive anywhere, requiring “nicotine content in mg per one nicotine pouch dose” plus the dose count plus a pack total, and capping both: “A unit packet must not contain more than 240 mg of nicotine and must contain at least 20 nicotine pouch doses”, and “One nicotine pouch dose may contain a maximum of 12 mg of nicotine.”
• Sweden requires a content declaration giving the nicotine in the product and its distribution per dose.
• Canada writes the distinction into the threshold itself, classifying pouches by whether they contain or deliver more than 4 mg per dose. Health Canada’s advisory states the result: “There are no authorized nicotine pouches in Canada that contain more than 4 mg of nicotine per dose.”

Canada’s drafting is the one to notice. Somebody there understood that content and delivery are different quantities and wrote both into the test so a product could not escape through either. Nobody else did.

And in the places with no rule, the labelling is worse than inconsistent. RIVM found that of its eleven products, the nicotine figure “werden vermeld op de verpakkingen van 8 van de 11 producten” — stated on eight of eleven packs — in milligrams per gram on some and milligrams per pouch on others, with the pouch weight given on only six, which is the number you need to convert between them. Three cans carried no nicotine figure at all. RIVM also noted the substitute many brands use: the figure “wordt vaak weergegeven als ‘sterkte’ op een puntenschaal (bijvoorbeeld 4 van de 5)” — a dot scale. Four out of five, of a maximum nobody defines. Our guide to mg per pouch versus mg per gram handles the conversion, and every brand’s strength scale compared deals with the dots.

Nobody checks the number

Here is the part that surprised me most. Having required the figure, no jurisdiction I examined — the EU, the UK, the US, Sweden, Denmark, Czechia — sets any tolerance on its accuracy, any test method for verifying it, or any consequence for getting it wrong. Czechia mandates three separate nicotine numbers and specifies no method for any of them. Denmark criminalises omitting the number and says nothing whatever about it being right.

Sweden is the sharpest illustration, because it has everything you would need. Folkhälsomyndigheten is the named supervisory authority over the content declaration on tobacco-free nicotine products, with statutory powers to issue injunctions and prohibitions. It has used them: in October 2025 it banned the wording “Skydd för tandköttet” — protection for the gums — from pouch packaging, ordered the manufacturer to tell its retailers and to recall the stock. A health claim, acted on firmly. The nicotine figure beside it has never been the subject of an enforcement action I can find.

Nor has it anywhere else. I searched the FDA’s warning-letter record, Sweden’s and Denmark’s enforcement material, and Health Canada’s advisories, and found no case anywhere of an authority acting over an inaccurate nicotine figure on a pouch. The FDA letters concerning pouches cite unauthorised products and underage sales; the milligram figure appears in them only as part of the product’s name. The EU’s rapid-alert database would not answer a query from here, so I cannot call that negative universal — but across every record I could actually read, nobody has ever been sanctioned for the number being wrong.

The FDA has even declined to check one. In its review of a nicotine pouch application, the agency recorded that nicotine in half the samples of one study was around 4.5 mg against a 6.0 mg target, that its own chemistry reviewers recommended independent verification — and then concluded that the discrepancy did not warrant verification testing. A 25% shortfall, flagged internally, and not measured.

Europe decided this figure misleads people — and then required it anyway

The last piece of this is the strangest, and it is sitting in plain sight in EU law.

The Tobacco Products Directive bans the nicotine figure from tobacco packaging. Article 13(1)(a) ends with the instruction that “labels shall not include any information about the nicotine, tar or carbon monoxide content of the tobacco product”. The reasoning is in recital 25: “the indication of the emission levels for tar, nicotine and carbon monoxide on unit packets of cigarettes has proven to be misleading as it leads consumers to believe that certain cigarettes are less harmful than others.”

Europe’s considered judgement, in other words, is that a nicotine content figure on a tobacco product misleads the people reading it. A Swedish health minister, answering a parliamentary question in 2016 about exactly this, put the reasoning in one sentence: “Anledningen till förbudet är att sådan information kan vara vilseledande, då en produkt med lägre innehåll av nikotin kan uppfattas som mindre skadlig än en annan.” The ban exists because a lower-nicotine product can be taken for a less harmful one.

Where the same Directive does require a figure, for e-cigarettes, it requires two: “an indication of the nicotine content of the product and the delivery per dose”. Content alone was judged insufficient, and the drafters had to carve e-cigarettes out of the Article 13 ban to allow it at all.

Nicotine pouches fall outside the Directive entirely and get neither treatment. And Sweden, which keeps its snus cans free of a nicotine figure because the EU judged such figures misleading, requires one on the tobacco-free pouch sitting beside it on the same shelf. Same mouth, same nicotine, opposite rules — and the figure that is mandatory on one is the one nobody verifies.

So what should you do with the number?

Use it, but use it for what it is.

Within a single brand and a single range, treat it as real. A step from 6 mg to 9 mg in the same product line is a genuine step up, the formulation is constant, and the independent human study above supports exactly that use.

Across brands, treat it as a rough band rather than a quantity. A 6 mg from one maker and a 6 mg from another are in the same part of the category and are not the same dose. Nothing about the figure licenses the arithmetic people do with it.

Treat your hold time as the real dial. It is the one variable in this entire piece that you control and that works the same way for every product.

And take a figure that is far from its neighbours with some scepticism. The highest numbers in the category are the ones the measurement studies most often find overstated, and a label is a claim, not a measurement.

Frequently asked questions

Is the number on the can wrong? Usually a little high. Six independent labs have measured commercial pouches and most products came in below their stated figure — the clean datasets run 80–95% of label, the worst single finding is around half. Occasionally a product measures above its label.

Does a higher mg always mean a stronger effect? Within one brand’s range, broadly yes. Between brands, no. Roswell Park measured one 3 mg pouch releasing under 1% of its nicotine in five minutes and an 8 mg releasing 90.8%.

Who checks these figures? Nobody, as far as any public record shows. Several countries require the number; none sets an accuracy standard, a test method or a penalty for inaccuracy, and no enforcement action over a wrong figure appears in any record I could search.

Why do some cans show dots instead of milligrams? Because nothing compels a number in most markets. RIVM found three of eleven cans with no nicotine figure at all, and noted that a points scale is commonly used instead.

What is freebase nicotine and why does it matter more than the mg? It is the uncharged form, and it is the one that crosses the lining of your mouth readily. Its proportion is set by the product’s pH, so two pouches with identical content can offer very different amounts of absorbable nicotine.

Is mg per gram better than mg per pouch? Neither is better; they answer different questions, and you cannot convert between them without the pouch weight, which most makers do not publish.
