Brief Summary

Smokeless tobacco (ST), which includes both chewing tobacco and snuff, has health risks associated with its use. While treatment programs that focus on stopping tobacco use may be effective, past research has shown that interventions that specifically focus on reducing tobacco use may be equally effective and may motivate individuals to eventually quit using tobacco. This study will compare the effectiveness of a ST reduction treatment program versus a usual tobacco cessation treatment program (immediate cessation) for reducing tobacco use in ST users.
