From your very first link:

It is interesting to note that the proportion in northern Europe is very low, as ‘Swedish snus’ does not seem to be linked to oral cancer. The results are of great importance both from a global health perspective and in terms of the health of migrants." says Cecilia Magnusson, co-author of the publication.

And the article in the Lancet also says:

“Evidence on the risk of oral cancer associated with using Swedish snus—a type of moist tobacco most commonly consumed in Nordic countries as pouches held in the mouth—is currently inconclusive, with several studies suggesting a significantly increased risk of up to three-times among ever daily snus users compared with never daily users, and others suggesting no statistically significant higher risk among current users compared with non-users, due to the much lower levels of NNN and NNK than in other smokeless tobacco products.”

Data from their own study shows that PAF-associated oral cancers are lower in Norway and Sweden compared to Northern Europe as a whole, despite them famously being the main consumers of snus.

I’m not saying snus is healthy. Using snus is definitely worse than not using any tobacco at all. But it is without a doubt a lot healthier than smoking.

Like I said in my first comment though, this is really of secondary importance. The most important thing is that you’re not increasing the cancer risk of people who happen to be in your vicinity by using snus. If every smoker switched to snus, the world would be a better place.
