A standard 24 gram can of Swedish portion snus holds 24 portions, which is about two and a half days for someone using the ten portions a day measured in daily users. Unopened and refrigerated, Swedish Match gives moist portion snus a shelf life of 20 weeks, moist loose snus 14 weeks and its dry range 30 weeks. Those are two completely different questions, and most of the confusion about how long a can lasts comes from running them together.
There are two ways to read the question in the title, and if you are new to snus itself rather than to the arithmetic, start there and come back. One is arithmetic: how many days of use are in a tin. The other is shelf life: how long the product in the tin stays worth using. I’ll do both, because the honest answer to the first depends on a number almost nobody publishes, and the answer to the second turns out to rest on a date most people misread.
What is actually in a can
Can formats are not standardised and the gram weight is not the portion count. The cleanest primary source for Swedish-style snus specifications is not a shop listing — it is the US Food and Drug Administration’s technical review of Swedish Match’s modified risk tobacco product applications, which itemises each product by weight, portion count and portion mass. From the application list in that review:
| Format | Net weight | Portions | Portion mass |
|---|---|---|---|
| General Loose | 45 g (1.59 oz) | not portioned | formed by hand |
| General Portion Original Large | 24 g (0.9 oz) | 24 | 1.0 g |
| General Portion White Large | 24 g (0.9 oz) | 24 | 1.0 g |
| General Mint / Wintergreen White Large | 24 g (0.9 oz) | 24 | 1.0 g |
| General Classic Blend White Large, 12-count | 10.8 g (0.38 oz) | 12 | 0.9 g |
| General Dry Mint Portion Original Mini | 6 g (0.21 oz) | 20 | 0.3 g |
Two things fall out of that table. First, the 24-portion, 24 gram, one-gram-per-portion can is the reference format — if someone says “a can of snus” with no other detail, that is almost always what they mean. Second, a smaller gram weight does not mean fewer days: the 6 gram mini can holds 20 portions, nearly as many as the 24 gram large can, because each portion weighs a third as much. The formats themselves I have compared elsewhere: loose versus portion, and who minis are for.
Swedish Match’s own US consumer site confirms the current American General line is uniform: the four blends are sold as “8mg/pouch, 24 pouches/can”. For loose snus, the can is sold by weight and the user forms each pinch by hand, so there is no published portion count and no sourced figure for what a typical hand-rolled prilla weighs. I have not found one, and I am not going to invent one — if you use loose, the only arithmetic available to you is grams per day, measured by how fast your own 45 gram cans empty.
The number nobody official publishes
To turn a portion count into days you need portions per day, and this is where the sourcing gets thin in a way that is worth being explicit about.
Sweden’s own public health agency measures how often people use snus, not how much. Folkhälsomyndigheten’s national survey reports that in 2024, 22 per cent of men and 10 per cent of women aged 16 to 84 used snus every day, 4 per cent used it occasionally, and 5 per cent of the population used nicotine pouches daily. Those are frequency categories. There is no official Swedish figure for portions per day, and I could not find one at Statistics Sweden or at the tax authority either.
The best quantified figure I could source is peer-reviewed and Finnish. A 2021 study in BMJ Open of 1,280 young Finnish male conscripts, sampled at random from three Finnish Defence Forces units, found: “On average, daily snus users consumed 10 portions and occasional users three portions per day (p<0.001). The daily total exposure time for daily users was 372 min (95% CI 344 to 401) and for occasional users 139 min (95% CI 106 to 171).” The paper’s competing interests statement reads “None declared.”
Ten portions a day is the number I’ll use below, and I want to be clear about what it is and is not. It is a mean among daily users in a sample of young Finnish men doing military service. It is not Swedish, it is not population-representative, it is self-reported, and it is the average of a distribution that certainly has a long tail. Use it as a reference point, not as a description of you. Whether a rising rate has gone too far is a different question, answered in signs of too much nicotine and how much nicotine in a day is too much.
There is a second, cruder signal worth knowing about: Swedish epidemiology routinely measures snus consumption in cans per week, which tells you something about what counts as normal. A pooled analysis of five Swedish cohorts covering 54,531 never-smoking men, published in the Journal of Internal Medicine in 2017, reported hazard ratios for type 2 diabetes “In individuals consuming 5-6 boxes per week” and “in those consuming ≥7 boxes per week” — in other words, a can a day is a recognised heavy-use band in Swedish cohort research, not an outlier. That paper’s PubMed record carries no funding statement, so I cannot tell you who paid for it.
How long a can lasts, in days
The arithmetic below is mine. Divide portions per can by portions per day:
| Format | Portions | At 5/day | At 10/day | At 15/day |
|---|---|---|---|---|
| Large portion can (24 g) | 24 | 4.8 days | 2.4 days | 1.6 days |
| White Large, 12-count (10.8 g) | 12 | 2.4 days | 1.2 days | 0.8 days |
| Dry mini (6 g) | 20 | 4.0 days | 2.0 days | 1.3 days |
| ZYN pouches, for contrast (6 g) | 15 | 3.0 days | 1.5 days | 1.0 days |
The ZYN row is there because the comparison surprises people. A can of pouches looks like a can of snus and weighs the same 6 grams as a dry mini, but FDA’s technical review of the ZYN applications specifies 15 pouches at 0.40 grams each in a 6 gram can — so it runs out faster than a mini snus can and much faster than a large portion can. If you have moved from snus to pouches and feel like you are buying tins more often, that is not your imagination; it is the format. That same portion-mass arithmetic is what makes strength labels hard to compare — see mg per pouch versus mg per gram and nicotine content in snus versus pouches.
At ten a day, a large can is roughly a two-and-a-half-day item and a week costs about three cans — which sits below the Swedish cohorts’ 5–6 band, while anyone in the “7 or more” band is getting through more than a large can a day, implying well over 24 portions.
Shelf life: what the maker actually says
Now the other question. Swedish Match publishes shelf-life figures in its own words, and they are more specific than anything a retailer will tell you:
“Snus is perishable and must be stored in a refrigerator for best shelf life. When stored correctly, the shelf life for moist loose snus is 14 weeks, for moist portion-packed snus 20 weeks and for the dry assortments 30 weeks. For longer storage, we would recommend freezing, which is excellent up to one year. Then, we recommend that the cans be vacuum-packed in airtight freezer bags. Snus in cardboard cans should be thawed in the refrigerator so that the condensation does not undo the glued seams in the cardboard can or the label on the outside of the can.”
Pouches are a different storage problem, handled in pouch shelf life and how to store a can. Three useful details in one paragraph: the moist/dry split, the one-year freezer ceiling, and the specific warning that a thawed cardboard loose-snus can can come apart at the seams if you let condensation get at it. The company also explains why the packaging differs by format — “Since portion-packed snus is more sensitive to drying out than loose snus, it requires a tighter can. Therefore portion-packed snus is packed in a plastic can.”
And there is a genuine contradiction between Swedish Match’s two websites that I think you should see rather than have smoothed over. The Swedish corporate site says snus “must be stored in a refrigerator”. The company’s US General site says the opposite about an opened can:
“No. After you open the can, it is not necessary to keep it chilled. General Snus should stay fresh the same amount of time, whether it is stored at room temperature or chilled.”
The same US site gives a figure the Swedish site does not: “Testing shows, under normal conditions, an unopened can of General Snus will maintain its quality (shelf life) for around 20 weeks. After that, it will begin to lose some of its freshness and flavor. Exposing General Snus to long periods of very hot conditions (i.e. storing it in a vehicle during summer months) can reduce shelf life.”
I would not try to reconcile those two positions, because as written they do not. What I take from them: 20 weeks unopened is the number both sites support, refrigeration is the Swedish company position for best shelf life, and heat — a car in July, not a warm kitchen — is the variable both single out. Keep snus in the fridge and you are following the manufacturer’s Swedish advice; keep an opened can on a shelf and you are following its American advice. Neither is reckless.
The date on a Swedish can is not a best-before date
This is the part that changes how you read your own tin, and it is a correction I had to make to my own assumptions.
Swedish labelling rules for snus sit in food law, not tobacco law, and the current instrument is the Swedish Food Agency’s LIVSFS 2024:2, which came into force on 1 April 2024 and repealed the older LIVSFS 2012:6. Section 12 lists what a consumer pack must carry: “1. Nettokvantitet i gram. 2. Tillverkningsdag. 3. Förvaringsanvisning, om förvaringen har betydelse för hållbarheten. 4. Namn på och adress till tillverkaren, förpackaren eller säljaren.”
That is: net quantity in grams, date of manufacture, a storage instruction where storage affects keeping quality, and the maker’s name and address. I searched the full text for “bäst före” and for “hållbarhetsdatum” and found neither. Swedish law does not require a best-before date on snus. It requires the date the snus was made.
Swedish Match does print one anyway — “We always label the snus cans with a ‘Best before’ date. When you keep it refrigerated, snus will usually stay fresh much longer than that date” — and its US site confirms the American convention plainly: asked what the date code on the bottom of the pack is, the answer is “This is the ‘Best Before’ date.” So the practice is real, but it is company policy going beyond the regulation, not a legal requirement, and the two dates run in opposite directions. A manufacturing date is something you count forward from. A best-before date is something you count down to. If you are looking at a Swedish can and treating the printed date as an expiry, you may be reading it backwards.
The other consequence of section 12 is quietly useful: because net quantity in grams is mandatory on every consumer pack, you can always check your own format against the table above rather than trusting a product description.
What actually happens to an old can
Swedish Match’s answer is unglamorous and, I think, accurate: “Most often old snus just dries out and loses much of its aroma and flavor. There is a very small risk that it will start to mold. Snus is not normally unhealthy when it gets too old but still, just like any food, if it smells bad, don’t use it.”
Drying out is the main event because there is a great deal of water to lose. A 2018 analysis in Nicotine & Tobacco Research compared industry reports filed with the Massachusetts Department of Public Health and found Swedish-style snus products had significantly higher “moisture (median: 30.3% vs. 53.4%; p < .001)” than American snus — the 53.4 per cent figure being the Swedish-style median. The study was funded by a National Cancer Institute training grant (T32 CA057726) and declares no competing interests. At that moisture level, roughly half the mass of a moist can is water, which is why a dried can feels light and tastes like nothing, and why moisture changes so much. The pasteurisation behind this shelf life is part of how Swedish snus is made.
On whether old snus becomes microbiologically unsafe, there is now a directly relevant experiment, and its answer is reassuring in a slightly counterintuitive way. A 2025 study in Frontiers in Public Health, supported by the US Food and Drug Administration under grant UC2FD005671 and declaring no commercial conflicts, stored reference smokeless tobacco products — including a Swedish-style snus — for twelve months at −20 °C, 4 °C and 22 °C. For the snus, “storage temperature did not influence bacterial community composition”, and culturable bacteria actually fell at room temperature over time, which the authors attribute to drying: three of the four products had a lower culturable load after long-term storage at room temperature, “which may be due to a loss of moisture content”. Their overall conclusion on long-term storage is that “storage at −20 °C is sufficient for long-term storage of the reference products” — which is the freezer advice, arrived at independently.
So the room-temperature penalty for Swedish snus looks like a quality problem rather than a safety one. That is consistent with the manufacturer’s “very small risk that it will start to mold” and with the preservation chemistry the Swedish regulation permits: LIVSFS 2024:2’s annex caps potassium sorbate (E 202) and propionates (E 280–283) at 2 g/kg each and propylene glycol (E 1520) at 40 g/kg, that last one being the humectant that keeps the product moist in the first place. Swedish Match describes salt and pasteurisation doing the rest: the mixture “goes through a heat treatment, a pasteurization aimed at neutralizing microorganisms and give the snus a longer shelf life.”
Is snus legally food in Sweden? No — and the myth has a source
You will read everywhere, including on Swedish Match’s own website, that snus is legally classified as food in Sweden. It is not, and the regulator says so in one sentence.
Livsmedelsverket, the Swedish Food Agency, states: “Snus, snusliknande produkter och tuggtobak är inte livsmedel enligt definitionen av livsmedel i artikel 2 i förordning (EG) nr 178/2002.” Snus, snus-like products and chewing tobacco are not food under the EU definition. The agency then explains what Sweden does instead: the products “i 3 § livsmedelslagen jämställts med livsmedel som en lagteknisk lösning” — they have been equated with food in section 3 of the Food Act as a legal-technical solution, so that selected parts of food law can be applied to them.
The statute reads exactly that way. Livsmedelslag (2006:804) section 3: “Med livsmedel jämställs i lagen … 2. snus, snusliknande produkter och tuggtobak.” The verb is jämställs, equated with, not är, is. And a 2024 amendment, Lag (2024:23), added “snusliknande produkter” — snus-like products, meaning tobacco-free nicotine pouches — to that same list, pulling white pouches into the same regime.
The practical consequences people cite are real: food-grade additives only, food hygiene and HACCP requirements on manufacture, a food agency as the regulator, and the storage-instruction rule that is the reason your can says to keep it cold. What is wrong is the shorthand. The origin of the error is easy to find, because Swedish Match publishes it: its own FAQ says “In Sweden, snus is legally classified as food”, and its US site says “Because General is manufactured in Sweden, it is classified as a food product.” I would treat both of those as marketing-grade statements of a legal position, not as the legal position. The regulator’s own wording is available and says the opposite. Much of what people credit to food law is actually the voluntary GOTHIATEK standard, and the regime exists only in Sweden for the reasons behind the EU snus ban.
FAQ
How many portions are in a standard can? Twenty-four, in the 24 gram large-portion format, at one gram each. The 12-count white large can has twelve 0.9 gram portions, and the 6 gram dry mini can has twenty 0.3 gram portions.
How many days will one can last me? If you use around ten portions a day — the mean among daily users in the Finnish conscript study — a large can is about two and a half days and a week costs roughly three cans. Your own rate is the only figure that matters: note the date you open a can and the date it empties. Still choosing what to buy? Start with the master ranking.
Does snus go off? It dries out and loses flavour. Swedish Match gives unopened moist portion snus 20 weeks refrigerated, moist loose 14 weeks and its dry range 30 weeks, and says the mould risk is very small but that you should not use a can that smells bad. An FDA-funded storage experiment found no shift in the bacterial community of Swedish-style snus across twelve months at freezer, fridge or room temperature.
Can I freeze it? The manufacturer says yes — “excellent up to one year” — and recommends vacuum-packing the cans in airtight freezer bags. If it is a cardboard loose-snus can, thaw it in the fridge, because condensation can undo the glued seams.
Do I have to refrigerate an opened can? Swedish Match’s Swedish site says snus must be refrigerated for best shelf life; its US site says an opened can does not need chilling and stays fresh the same length of time either way. Both sites agree that sustained heat — a car in summer is the example both give — shortens shelf life.
What is the date on the bottom of the can? On a Swedish can, the legally required date is the date of manufacture, not a best-before date. Swedish Match prints a best-before date voluntarily as well, and the date on a US General can is a best-before date. Check which one you are looking at before you treat it as an expiry.
Is snus regulated as a food in Sweden? It is regulated under food law without being food. Livsmedelsverket states that snus is not food under the EU definition; section 3 of the Swedish Food Act equates it with food so that parts of food law apply.
