A nicotine pouch is a sealed pouch of plant fibre filled with nicotine, a moisture regulator, flavouring and sweetener. It contains no tobacco leaf, the nicotine is added to a neutral fibre base rather than derived from a cut tobacco filler.
That single distinction drives most of the regulatory difference between pouches and snus in Europe. Snus is tobacco for oral use and falls under the EU Tobacco Products Directive,
Directive 2014/40/EU, which keeps it off the market in every member state except Sweden. Tobacco-free nicotine pouches sit outside that directive — which is why they are regulated market by market rather than by one EU-wide rule.
Pouches are sold in cans, usually with an upper compartment in the lid for used pouches.
