Looks like my information is a bit outdated. Some published research do state that snus cause increased risk of certain cancers (e.g. esophageal, pancreatic, stomach cancer, colorectal, oral and pharyngeal cancer), but some newer research suggest that this inconclusive.

The other primary risks are things which tie more to nicotine in general (like stroke & various effects on pregnancy including increased risk of stillbirth).
