Statistics suggest that its not that dangerous, iirc any tobacco use carries with it a very small but not non-existent risk of pancreatic cancer from the nicotene and it cant be good for your gums. If you keep doing it your gums will probably recede, but according to the numbers there is almost zero chance that snus will cause serious health problems for you. At least the pasteurized stuff produced under swedish food prep regulations.
Still its addictive and addiction robs you of at least some of the equanimity that you might have otherwise. You might try cutting down the dose first with mini-portions instead of going cold turkey.
