Smokeless tobacco use among urban white and black South Africans.

A telephone survey was conducted to compare the extent of smokeless tobacco use and perception of related health risks by white and black urban South Africans. Using systematic random sampling, one out of every 20 phone numbers was selected from the Seshego (blacks) and Pietersburg (whites) telephone directory until 300 tobacco users in each site were identified. Among the white group, cigarette smoking was clearly predominant (290) and only 10 used snuff, whereas among the black sample almost half (46.7%) of the tobacco users used snuff, especially women (40%). Although a majority acknowledged negative effects of snuff use on their health and its addictive character, 42% either do not believe or do not know that snuff contains nicotine and causes cancer.
