How many uses of smokeless tobacco can give you mouth disease?

my freind and i went to the country for the last two weekends and we used smokeless tobacco just for the heck of it. only for two days each time. i was just wondering, cuz it says on the package that it can give you mouth cancer, how long does it take to contract said mouth disease? whats the minimum number of uses?

There is no minimum number of uses, and it depends on the person. And any use of it can cause it, of course the more you use the higher your chances are.
