Legality
Based on studies at the time was believed to be a strong association with cancer and a fairly low usage outside of North America and several countries have banned the sale (and in some cases the import) of dipping tobacco. Sale of dipping tobacco was banned in South Australia in 1986 and across the country in 1991 and in most of the EU nations in 1992. Sweden was exempt from this ban because of the traditionally high usage of snus in that country.
In the USA it is illegal to sell dip to persons under the age of 18 (except in Alabama, Alaska, New Jersey, Utah, and the Counties of Suffolk County, Onondaga and Nassau in New York State where the age requirement is 19).
Companies are now required to place very large warning labels that comprise at least twenty percent of all advertisements and thirty percent of two principal display panels on each tin.
