Oral snuff and chewing tobacco, commonly referred to as smokeless tobacco, are being used by many adolescent and young adult males, and no indication exists that use by this group is declining. Users are at risk for oral cancer, noncancerous oral pathology such as leukoplakias, and addiction. Information about patterns of smokeless tobacco use and motivations of users may help planners develop and implement interventions. Variables include the importance of peer and family influences, social image, knowledge of harmful effects, regional differences, use of other substances, and addiction. Due to the addictive nature of smokeless tobacco, older youth may need cessation programs. Health educators are encouraged to include smokeless tobacco in their tobacco use prevention programs and to develop and implement comprehensive tobacco interventions appropriate for their youth population.
