Actually there’s virtually no clinically substantiated link between snus use and any kind of cancer, including oral. They had to take the cancer warnings off the packaging in Sweden a few years ago (the warnings had been basically automatically included because tobacco, but then it was pointed out there was no demonstrable link, unlike the vast majority of tobacco products).
People forged a mental link between snus and visually similar but highly carcinogenic American products like Skoal Bandits years ago. As a result of that, and lobbying by tobacco firms which don’t have proper snus products to sell, an EU ban has been upheld despite plenty of evidence that snus is dramatically effective as a smoking cessation aid, and is around 95% safer than smoking (similar to vaping IIRC).
Lifting the ban on snus (and only snus, made in the proper Swedish way - no letting tobacco companies broaden the definition to include ‘chew’ or anything like that) could save lives.
