Summary
This research study will determine if using a combination of 4-mg nicotine lozenges,
self-help materials, and/or telephone tobacco cessation counseling will help smokeless
tobacco users stop using tobacco. The study will consist of three interventions:
1. The Lozenge Assisted Self-help intervention - lozenge nicotine replacement therapy,
phone counseling, and self help materials
2. Assisted Self-Help intervention - self-help materials and phone counseling without
lozenges
3. Lozenge Self Help intervention - self help materials and lozenge nicotine replacement
therapy.
Hypothesis: The Lozenge Assisted Self-help intervention will significantly increase both the
prolonged and point prevalence for all tobacco and smokeless tobacco (ST) abstinence rates at
6 months among ST users who are interested in achieving tobacco abstinence, compared to those
in the Assisted Self-Help intervention and the Lozenge Self Help intervention.
