Help please? how long does it take to get cancer from dipping tobacco?

Good question: But the problem is nobody can answer for sure. I guess it would require exposure for a few years but remember that cancer is seldom a one hit deal, a person may have predisposing factors that could lead to cancer with shorter exposure. Since you can't know for sure, why risk it? If you dip, quit right away. If you don't, stay that way. Spittin' in a can is kind of nasty anyways....Ugh.
