Pamela,there is a lot of information on the main site here, but I would suggest that your husband read the stories of real people found here: http://www.oralcancerfoundation.org/people/index.htm These stories are both heartbreaking and inspirational, and above all, sobering. This might give him a look at what could be in his future. You are to be commended for trying to help him kick that dangerous habit. Good luck to both of you.
