all nicotine is very clearly damaging to the heart and brain but it can help your gut and there’s no risk of cancer from pouches. Formaldehyde is present but formaldehyde is present in many foods too. It’s good to have a tobacco free nicotine made entirely of food grade ingredients.
it's worse. with chewing tobacco you get all kinds of chemicals the tobacco was cured and grown with, with nic pouches it's only nicotine and cellulose. can't get much cleaner than that.
Chewing tobacco is extremely bad for your mouth. Nicotine pouches have been linked to gum recession but not cancer. Nicotine pouches haven´t been linked to cancer (yet) but compared to dip they are safer.
