Snus (tobacco pouches you put under your gums) is super popular in Sweden:

It is basically the same thing but not synthetic. Supposedly nicotin pouches are not as harmful because they do not have tobacco leaves.

I am a bit ambivalent about it, on one hand people don't smoke as much because snus which means I don't get as much second hand smoke.

On the other hand it is WAY easier for kids to get started on it as they don't need to hide it after they put it in their mouths. I know a few people who are heavily addicted to it (one even keeps one in when he is sleeping) and they all started in their early teens.
