How much nicotine is absorbed from a snus portion
About a third of the nicotine in a snus portion leaves the pouch in an hour, and roughly 40-60% of that reaches the bloodstream. What five measurements from three tobacco companies and one NCI-funded lab actually establish.
About a third of the nicotine in a snus portion leaves the pouch during an hour of use, and roughly 40–60% of that reaches the bloodstream. For a standard 1 g portion holding 8 mg, that works out at somewhere between one and one and a half milligrams actually absorbed. The figure on the can is not the dose. Hold time is what moves the number: twenty minutes gives up about an eighth of the nicotine, an hour about a third.
This is one of the few questions about snus with replicated measurements behind it, and also one where the most repeated number is wrong. Two definitions first, because the subject collapses without them. If you are new to the product itself rather than to the arithmetic, start with the complete guide to snus. Extraction is the nicotine that leaves the pouch and enters your mouth. Absorption is the smaller fraction of that which crosses into your blood rather than being swallowed and broken down by the liver. Most of the confusion in this area comes from sources that use the two words as though they meant the same thing.
What is actually inside a portion
The best non-industry measurement of what a portion contains comes from a Roswell Park Comprehensive Cancer Center team, funded by the National Cancer Institute, who assayed eleven tobacco pouch products from seven brands alongside a batch of tobacco-free pouches. They describe it as “the first non-industry study to compare nicotine content, release, form, and select flavoring composition between multiple ONPs and OTPs.”, with “The CORESTA smokeless tobacco reference product (CRP1.1 Swedish-style snus pouches) was included as an analytical control.” Nicotine in the tobacco pouches ran from 4.5 mg per pouch (General) to 26.4 mg (Bull Dog), averaging 12.3 mg against 6.4 mg for the tobacco-free pouches, at masses from 0.6 g (Camel) to 1.6 g (Copenhagen).
And here is the finding I did not expect. Measured per gram of pouch material, snus and tobacco-free pouches held statistically indistinguishable amounts of nicotine — 14.3 against 14.6 mg/g. The reason a snus portion typically holds twice the nicotine of a modern pouch is almost entirely that it weighs twice as much: 0.9 g against 0.5 g on average. It is mass, not strength — which is the mechanism behind the gap set out in nicotine content in snus versus nicotine pouches.
Germany’s Federal Institute for Risk Assessment (BfR), reviewing a US dataset, gives a similar spread: snus pouch weights of 0.33 to 1.13 g at concentrations between 6.81 and “20.6 mg/g [8].” A 1 g portion at 8 mg/g sits near the middle of all of these ranges.
How much of it leaves the pouch
The method is simple, and the papers say so plainly: “The nicotine content of snus and gum portions was measured in separate samples taken both before and after use.” Whatever is missing afterwards went into the mouth. Six measurements, across three companies and two decades, line up like this:
| Study | Product and hold time | Subjects | Nicotine extracted | Funder |
|---|---|---|---|---|
| Digard et al. 2013, Nicotine & Tobacco Research | Four Swedish snus products, 60 min | 20 | 24%–32% | British American Tobacco |
| Digard et al. 2013, Chemistry Central Journal | 1 g pouched snus, 60 min, 63 pouches | 21 | 33.3% (median 32.7%) | British American Tobacco |
| Lunell & Lunell 2020, reported by BfR | General 8 mg, 60 min | 17–30 | 32.0% and 32.6% | Manufacturer (per BfR) |
| Lunell & Lunell 2005, as characterised by Digard | Four Swedish snus types, 12 doses over a day | — | 22%–44% | Not obtainable |
| Imperial Brands, NCT04891406 | Skruf snus 10.9 mg, 20 min | 24 | 12.56% | Imperial Brands |
| Imperial Brands, NCT05452278 | Tobacco pouch 16.6 mg, 20 min | 27 | 14.0% | Imperial Brands |
The headline result of the 2013 clinical study is unambiguous: “the percentage of nicotine extracted from the products was highest for the nicotine gum, with 63% extracted. For snus products the mean extraction during use was between 24% and 32%.” Gum, which you chew, gives up twice what a portion does.
The companion paper is the stronger design, because it was not run in a clinic. Twenty-one habitual users used pouches at home in their normal way — “At each session four snus pouches were used consecutively by each subject” for an hour each, and “Subjects were asked to use the product in their normal manner, with no restriction on pouch movement.” Across 63 pouches, a portion containing 9.6 mg came out containing 6.4 mg: 3.2 mg transferred, 33.3% on average, measured on the pouches as they left the mouth (“All analytical data were generated on samples as received with no correction for pouch mass or water content (i.e. wet-weight basis).”). Two thirds of what you paid for goes in the bin.
Hold time is most of the answer
Every sixty-minute study picked that figure for the same reason: “Subjects used snus samples for 60 min, which was the median reported time period for an individual session of use observed in the survey.” The only measurements at any other hold time are two Imperial Brands trials whose results were posted to the US clinical trials registry rather than published. One tested “Skruf snus fresh slim white, 10.9 mg nicotine/pouch” and reported the “Extraction fraction (%) of nicotine in used product pouches after 20 minutes of use.” at 12.56%; the other, measuring the clumsily titled “Percentage of Orally Extracted of Nicotine” from a “Tobacco pouch, 16.6 mg nicotine/pouch, used for 20 minutes”, reported 14.0%.
So: roughly an eighth at twenty minutes, roughly a third at sixty. The curve is steep early and incomplete even at an hour, and nobody has published a single intermediate point. The 2013 authors asked for exactly that study — understanding the importance of usage time, they wrote, “would require a dedicated time-course study covering usage durations from 20 to 120” minutes. Thirteen years on, it has not been done.
That matters, because the literature is measuring a behaviour most people do not perform. BfR’s survey of 150 German users found the most popular hold was ten to twenty minutes, with only 15% to 25% holding a pouch for twenty to thirty; the 2013 authors conceded the gap from the other side, noting that “most nicotine pharmacokinetic studies on snus are based on a usage time of 30 min.” If you are a twenty-minute user, your absorbed dose is roughly a third of what the sixty-minute figures imply.
How much of what leaves the pouch reaches your blood
Extraction is not absorption. Nicotine that dissolves into saliva and is swallowed goes to the liver first, where most of it is destroyed before reaching the circulation. BfR puts it plainly: nicotine is “absorbed directly via the oral mucosa. Some of the nicotine may also be dissolved in saliva” and then swallowed, where that fraction can be reabsorbed through the gut.
There is exactly one snus-specific number for the surviving fraction, and it comes from a crossover study of four Swedish snus types against 2 mg nicotine gum: “The approximate bioavailable dose of nicotine from snus was 40%-60% of the extracted dose.”
Read the method before using that figure. It is a relative bioavailability, not an absolute mass-balance recovery — “Relative bioavailable dose was calculated using AUC of 2-mg Nicorette gum as the reference.” — measured at steady state across twelve doses in a day, not from a single portion. As “roughly half of what leaves the pouch, benchmarked against nicotine gum”, it is sound; as a hard percentage, it is overclaimed.
The broader pharmacology agrees on the order of magnitude. A review chapter funded by the US National Institute on Drug Abuse — “Much of the research described in this chapter was supported by US Public Health Service grants DA02277 and DA12393 from the National Institute on Drug Abuse, National Institutes of Health” — puts oral mucosal products in the same band: “Bioavailability for these products with absorption mainly through the mucosa of the oral cavity and a considerable swallowed portion is about 50”–80%. The same chapter explains why the gap exists: “The absolute dose of nicotine absorbed systemically from nicotine gum is much less than the nicotine content of the gum, in part, because considerable nicotine is swallowed with subsequent first-pass metabolism”. It contains no snus row and no pouch row at all, so I am using it for the mechanism, not the number.
The arithmetic, and the multiplication is mine rather than any source’s. A 1 g portion holding 8 mg, held for an hour, gives up about a third — call it 2.4 to 2.7 mg, which is what the Swedish measurements actually recorded for General. Forty to sixty per cent of that reaches the bloodstream. That is roughly 1.0 to 1.6 mg systemically absorbed, and around 0.4 to 0.6 mg at twenty minutes. I would not put more precision on it than that; the measured spread is wide enough to swallow a decimal place.
Snus against a cigarette, in the same experiment
Only two studies have put a snus portion and a cigarette in the same subjects on one protocol, and they agree on a result most people find surprising.
| Measure | Cigarette | Pouched snus, 10.7 mg, 60 min | Loose snus, 27.1 mg, 60 min |
|---|---|---|---|
| Peak plasma nicotine (Cmax, ng/ml) | 12.8 | 10.8 | 17.9 |
| Total exposure over two hours (AUC, ng.h/ml) | 14.8 | 16.8 | 26.9 |
| Time to peak (median, hours) | 0.117 | 1.00 | 1.00 |
A cigarette peaks about eight times faster and slightly higher. The snus portion delivers more total nicotine over the following two hours. Both facts come out of one twenty-subject crossover. The Imperial data at twenty minutes points the same way: a peak below the cigarette’s, with cumulative exposure above it.
The shape is the point, and the NIDA-funded chapter describes it well: “Concentrations of nicotine in the blood rise gradually with the use of smokeless tobacco and plateau at about 30 min, with levels persisting and declining only slowly over 2 h or more”. BfR’s reading of the Swedish pharmacokinetic data gives a single-portion peak of 10.6 ng/ml at 69 minutes with a half-life of 144 minutes. A cigarette is a spike; a portion is a plateau. What happens after the plateau is a separate question, and one the half-life figures answer rather than the extraction figures — see nicotine half-life and how to space your pouches.
The 1988 study usually cited for this pattern found exposure “twice as large after single exposures to smokeless tobacco compared with cigarette smoking” — but it tested American oral snuff and chewing tobacco, at a different pH and mass, so I would not read it onto a Swedish portion.
What changes the number, and what does not
Loose or portion makes no difference. At matched weight and matched nicotine, the two formats behaved identically: “The similar nicotine pharmacokinetics for 1 g portions of loose and pouched snus, both containing similar levels of nicotine (10.8 mg and 10.7 mg, respectively), suggested that product form was not a major influencing factor in this study.” The pouch is a convenience, not a dose modifier; the practical differences between the two formats are covered in loose snus versus portion snus.
A bigger portion is not a proportionally bigger dose. Extraction “it was dependent on the total amount of nicotine in the snus portion”, but the authors found the relationship “sub- proportional” — their hyphenation, not mine. Two and a half times the snus produced about 1.6 times the exposure. Doubling up does not double your dose.
pH decides how much of the nicotine is in the absorbable free-base form, and the spread across products is enormous. The Roswell Park team measured “pH of OTPs ranged from 6.8 (Copenhagen) to 9.4 (Siberia)”, “which corresponded to 5.2% versus 96.0% freebase nicotine.” Two tins with similar nicotine labels can present very different amounts of readily absorbed nicotine to the same mouth.
Mechanical work barely enters into it, which is why snus extracts so much less than gum. Users “relatively saliva-poor area between the upper jaw and cheek for an hour on average, and undertake relatively little mechanical work”, in the authors’ description. Gum is chewed; a portion sits.
Your metabolism matters less than you would guess. The one genotyped snus study classified its subjects by CYP2A6 activity — “CYP2A6 genotyping classified 12 subjects as extensive metabolizers and eight subjects as intermediate metabolizers.” Exposure ran 10% to 30% lower in the fast metabolisers, a real direction, but the authors declined to claim it: “Overall, the measured CYP2A6 metabolic status of the subjects did not have an impact on the pharmacokinetic end-points measured.” In twenty people, with eight intermediates, that is the honest call.
And the most useful finding for anyone asking this about themselves. The 63-pouch study decomposed the variability in nicotine extraction: measurement error 3.9%, variation between people 9.5%, and variation within the same person from pouch to pouch 16.2%. For nicotine — alone among the dozen constituents tracked — your own next portion is less predictable than the gap between you and a stranger. The paper’s headline conclusion, that extraction is driven by between-subject differences, holds for the other constituents and not for this one. Named but unmeasured: “moving the snus portion around the mouth, spitting saliva during use, or swallowing some amount of loose snus.”
The number you will see quoted that I will not print
“Snus releases 86% of its nicotine” circulates widely. There is no source for it: the figure appears in no extraction study. What exists is a free-base fraction in BfR’s pouch assessment — the median proportion “of free-base nicotine was 86% [3].” — which is a statement about chemical form in nicotine pouches, not about how much nicotine leaves a snus portion. A separate 86% in the Swedish market literature is portion snus’s share of cans sold. Three unrelated numbers, one of them attached to the wrong question.
BfR’s own prose helped the confusion along. It writes that the Swedish study “shows that after 60 minutes of use, at least half of the nicotine” contained in the pouch is absorbed — while the column header in the table it cites reads “Extracted nicotine” as a percentage of total content, and the two Swedish snus rows in that table read 32.0% and 32.6%. “At least half” is true of the three nicotine pouch rows (55.9%, 59.1% and 50.4%). It is not true of the snus rows, and “extracted” is not “absorbed”. BfR itself states the snus figure correctly a page earlier: extraction values “were 19% for the American product and 33% for the Swedish product (see table 3). Some” variation aside, that is the number.
The other source of inflated figures is laboratory release testing, and the laboratory is scrupulous about it. Roswell Park found that “Among OTPs, only Copenhagen, General, and Grizzly released at least 80% of their nicotine content after 5 minutes.” — in a 50 ml beaker of water on a magnetic stirrer at 350 rpm. They say outright what that is for: “To compare products systematically, we used an experimental approach to facilitate maximal and more rapid nicotine release from products, rather than replicate human oral use.” Their method also censors its own upper tail: “If the measured release exceeded the measured total content due to instrument variation, the released percentage was 100%.” A beaker is not a mouth.
Who paid for these numbers, and what no authority states
This has to be said because it is the most important limitation on everything above. Every in-vivo measurement of snus nicotine extraction in existence was produced by a tobacco company.
The two 2013 papers were BAT’s. One carries the funding line naming “British American Tobacco (Investments) Ltd”; in the other, “All authors are employees of British American Tobacco, which is a producer of snus.” The first paper’s declaration of interests covers only its single academic co-author — “Dr Malmqvist does not act as a consultant for British American Tobacco and has no financial interests in the Company” — and says nothing about the four company authors. The 2020 extraction comparison came from a team including Swedish Match’s product science group; its funding statement is behind a paywall I cannot reach, but BfR records it for us as a study “financed by a manufacturer”. The two twenty-minute datasets are Imperial Brands’. The pouch pharmacokinetics most often cited alongside these were “The study was supported by British American Tobacco (Investments) Limited, the manufacturer of Lyft and Velo smokeless oral nicotine pouches.”
The only non-industry laboratory work here is the NCI-funded content and release study — “Research reported in this publication was supported by the National Cancer Institute (NCI) of the National Institutes of Health under Award Numbers U54 CA228110 and P01 CA200512.” — and it is a stirred beaker that says it is not a mouth.
That is not a reason to discard the numbers: three rival companies over two decades converged on about a third in an hour, and that kind of agreement is hard to manufacture. It is a reason to notice what has not been published. At least six further company-run snus pharmacokinetic trials have completed since 2007 without reporting a figure, including one on two named General products whose registered design promised that “Mean + SD extracted dose of nicotine from each preparation will be estimated.” It completed in January 2007. Nothing was ever posted.
No regulator states an absorbed dose per portion, a usage interval, or a maximum. I checked the US position directly, because it is the one most often assumed to exist. The FDA page listing authorised oral nicotine products says “There are 67 nicotine pouch products authorized by the FDA. These are the only nicotine pouch products that may be lawfully sold in the United States.” and lists strengths. Across the whole page, the words “dose”, “absorb”, “bioavailability”, “interval”, “per day” and “maximum” appear zero times. It is a marketing-authorisation list, not guidance on use — and FDA attaches its own standing caveat: “While these products are authorized to be sold in the United States, it does not mean these products are safe, nor are they “FDA approved.” All tobacco products are harmful and potentially addictive.”
Nothing here is a safety statement, and the absence of an official figure is not a licence to invent one. If you are trying to control your intake, the levers the evidence actually supports are hold time first, portion mass second, and the number printed on the tin a distant third. Where a particular product sits on that range is a different question, and the master ranking is where this site keeps that comparison.
Frequently asked questions
Does an 8 mg portion give me 8 mg of nicotine?
Not close. A third leaves the pouch in an hour and about half of that reaches the bloodstream, so an 8 mg portion delivers on the order of 1 to 1.6 mg.
Does holding it longer get me more?
Yes, substantially, up to at least an hour: about 12%–14% extracted at twenty minutes against about 32% at sixty. Beyond an hour nobody has measured it.
Is loose snus stronger than portion?
Not per gram, and not pharmacokinetically. At matched weight and nicotine the two performed identically. Loose tends to deliver more because people take more of it.
Do nicotine pouches give up more than snus?
Yes, consistently, and two rival manufacturers found it independently at two different hold times. In the Swedish comparison, “The extracted fractions of nicotine for both ZYN products (56% and 59%) were significantly larger than for 8 mg General (32%).” The practical consequence is counter-intuitive: “Less nicotine was extracted from ZYN 3 mg (1.5 mg) and more from ZYN 6 mg (3.5 mg) than from 8 mg General (2.4 mg).” A 6 mg pouch can out-deliver an 8 mg portion. The same arithmetic runs through nicotine pouches versus nicotine lozenges, and the upper end of the strength range is measured in the strongest nicotine pouches in the world, by measured content.
Why do my own portions feel inconsistent?
Because they are. Variation within one person from pouch to pouch was measured at 16.2%, against 9.5% between different people. Hold time, saliva, placement and swallowing account for more than genetics do.
