The prevalence of smokeless tobacco is significant and reaches as high as 17% past month use in white males aged 18-25. Smokeless tobacco use is of concern because of the potential for addiction and the associated negative health consequences. This article reviews the basis for addiction to smokeless tobacco, examining the nicotine content in smokeless tobacco products, pharmacokinetics, psychoactive effects, tolerance, and withdrawal. ⋯ Furthermore, it examines the factors associated with the initiation of smokeless tobacco use, and the current prevention programs that address these factors. Current smokeless tobacco treatment approaches are also discussed as well as predictors for abstinence. Finally, the future directions are discussed in light of the limited amount of research that has been conducted in the smokeless tobacco area, particularly related to prevention and treatment.

Commercial tobacco products are the leading causes of preventable death, yet they are virtually unregulated. They are popular because they are effective nicotine delivery devices, and the most addictive product (the cigarette) is also the most likely to kill.

Mass media are particularly appropriate for reaching young people in smoking-prevention campaigns; however, past research has placed little emphasis on designing effective interventions. Only a few studies have been conducted to develop and evaluate methods to use media for smoking reduction among youth, and only one quasi-experimental study has demonstrated actual reductions in youth smoking. This research requires the use of large controlled field studies that cross disciplines. ⋯ Furthermore, campaign approaches seeking to reduce youth demand for tobacco products are currently receiving less attention from anti-tobacco policy makers than approaches restricting the supply of tobacco to youth. Scientists from various health behavior and education disciplines should join with creative media production professionals to develop more effective messages and message delivery systems to reach youth at high risk of smoking. Further efforts should be made to share information among these professionals and producers of entertainment programs for youth, as well as among anti-tobacco policy makers, so that the most effective approaches can be employed to reduce youth smoking on a broad scale.
