A tiny tobacco pouch that you put under your lip.
Theres different flavors and strength levels, they go from level1 (weakest ones) to level 5(strongest).
The first time taking snus (if you take from the strong ones) the effects will be
pretty strong and they last for about 10-20 minutes, at first you'll need to wait for about a
minute to feel the effects, you get relaxed, a small domapine rush, then your whole body starts to get tingly, your fingers go almost numb and you become a little
bit sleepy.
If you're a smoker it's likely that the effects will not be that strong because your body is used to hangling nicotine.
