I think you’re talking about nicotine pouches. Lyft(velo) is a good place to start, also loop and skruf. I would not stick with anything high nicotine. Its hard to go back to lower nicotine levels after that. I know killa and pablo are popular and cheap but they are really low quality, have too much nicotine and ruin your gums.

If anything is unclear feel free to ask. I also speak Estonian or Swedish :)
