Nicotine pouches dry out over time. Dry pouches release more slowly and the flavor fades. How long a can stays usable depends mainly on how it is stored.
Cool and closed
Unopened cans keep longest in the refrigerator. Room temperature is possible, but shortens shelf life. Direct sunlight, proximity to heaters and the glove compartment of a car are the most common reasons for dried-out cans.
Opened cans
After opening, close the lid tightly and store the can in a cool place. The less often it stands open, the longer the moisture is retained.
Freezing
Unopened cans can be frozen to keep them longer. After thawing, they should not be refrozen.
Best-before date
The date is on the bottom or the edge of the can. It refers to unopened, properly stored products.
Out of the reach of children
Cans should be kept closed and out of the reach of children. Some cans have a child-resistant closure; this does not replace safe storage.
