Zyn vs snus: what is actually different

Side by side

What is in each

Snus is an oral tobacco product that originated in Sweden: ground tobacco, heat-treated and sold loose or in portions. Because it is tobacco, it contains tobacco-specific nitrosamines (TSNAs), among the most potent carcinogens in tobacco products. A CDC analysis of 64 snus products found them in all of them, at levels that varied more than tenfold; Swedish-style pasteurisation keeps them lower than in many other smokeless products.^[2]

Zyn and other nicotine pouches replace the tobacco with a powder of nicotine, flavourings and other ingredients in a microfibre pouch.^[1] Without tobacco leaf, most of the TSNA problem goes away, although Germany's risk-assessment institute found traces of TSNAs in some pouch products it tested.^[3]

The name confusion comes from Sweden, where tobacco-free pouches are often called white snus. In Norway, where tobacco-free pouches are banned, “white snus” contains a small amount of tobacco. For the rest of this page, “snus” means the tobacco kind.

Nicotine: strength versus delivery

Comparing milligrams across the two is misleading. Snus strength is often stated per gram, pouches per pouch, and what reaches your blood depends on how much nicotine the pouch releases.

In a crossover study run with Zyn's manufacturer, about 56 to 59% of the nicotine in Zyn pouches was extracted during use, compared with 32% from an 8 mg portion of General snus. As a result, a 6 mg Zyn produced about a third more nicotine exposure than the 8 mg snus portion, and a 3 mg Zyn about a quarter less.^[6] Strengths also span a huge range: in the German institute's tests, pouches ran from under 2 mg to over 47 mg each.^[3]

Health: what each does and does not avoid

Both deliver nicotine, and nicotine raises heart rate and blood pressure in the short term regardless of the route, which matters most for people with heart disease.^[10] Both are addictive. Neither is safe; the CDC says there are no safe tobacco products, pouches included.^[1]

The FDA has allowed both a General snus range and Zyn to say that using them instead of cigarettes lowers the risk of several diseases.^[8][7] Read those claims carefully: they compare each product with smoking, not with using nothing. If you do not smoke, neither claim is an argument for using them.

The real difference is tobacco. Snus carries tobacco-specific carcinogens that a tobacco-free pouch mostly does not. For quitting, though, the difference largely disappears.

Which is harder to quit?

Neither, as a rule. Both are nicotine products used many times a day, so both build the same dependence: Finland's medical library notes that snus users usually become more nicotine-dependent than smokers do,^[11] and a strong pouch habit can deliver as much nicotine or more.^[6] How hard your quit will be depends far more on how much nicotine you take and how early in the day than on whether it came with tobacco.

Withdrawal is the same: cravings, irritability, poor sleep and focus, peaking in the first week. See the withdrawal timeline.

Switching from one to the other to quit

Swapping snus for Zyn, or the other way round, keeps the nicotine dependence going. Finland's Terveyskirjasto lists snus and nicotine pouches as unsuitable aids for quitting,^[12] and the NHS points out that nicotine pouches are not licensed stop-smoking products.^[13] If you want nicotine help while you stop, licensed replacement products from a pharmacy, such as gum or lozenges, are the route health services recommend.
