OBJECTIVE: To evaluate telephone counseling for moist snuff use. METHODS: We recruited 221 adult males using snuff and randomized them into a telephone-counseling intervention or a quit-manual comparison group. Subjects were contacted by mail at 3 and 6 months to complete a 4-page follow-up questionnaire. RESULTS: A significantly higher proportion of subjects randomized to the intervention quit tobacco at each time point compared to the comparison group. CONCLUSIONS: With appropriate staff training, moist snuff and other types of nonsmoked tobacco should be added to the state-funded smoking cessation quit lines started in recent years.
