Varenicline and behavioural interventions may help ST users to quit. Behavioural interventions incorporating telephone counselling or an oral examination are likely to increase abstinence rates.
Smokeless tobacco cessation intervention for college athletes: results after 1 year.
The purpose of this study was to determine the efficacy of a college-based smokeless tobacco cessation intervention targeting college athletes.
                Sixteen colleges were matched for prevalence of smokeless tobacco use in their combined baseball and football teams and randomly assigned within college pairs to the intervention or the control group. One-year prevalence of cessation among smokeless tobacco users was determined by self-report of abstinence for the previous 30 days. Differences between groups were analyzed in a weighted version of the Fisher 1-sided permutation test for paired samples after adjustment for significant predictors of quitting other than the intervention (i.e., smokeless tobacco uses per week and most frequently used brand).
                Cessation prevalences were 35% in the intervention colleges and 16% in the control colleges when subjects with unknown quit status were defined as nonquitters. After adjustment for other significant predictors of quitting, the difference of 19% increased to 21%. The intervention effect increased with level of smokeless tobacco use.
                This intervention was effective in promoting smokeless tobacco cessation, especially among those who were more frequent users.
