3. Background Smoking-related deaths are projected to rise 10 million a year by 2020. Of this 70% of these deaths in poor countries. Lung cancer, one of the few malignancies for which the main cause is definitely known and that can be prevented. Tobacco smoking is the most important confounding factors in the lung pathology among mine workers.

4. Objective To study the prevalence of tobacco smoking among ex-mineworkers of the former republic of Transkei, South Africa.

5. Patients and Method During a period of two years (May 1997 to April 1999) 2,080 former mineworkers were examined at the Benefit Examination Clinic at Mthatha (Umtata) General Hospital, a tertiary hospital attached to the university of Transkei in Eastern Cape Province.

6. Results The number of smokers among mineworkers were very high (79%). The current smokers were 30%, and 21% had never smoked. The quitters were very high among all the categories of smokers. Ex-smokers (26%), smokers (17%), and non-smokers (9%).

7. Results The current smokers were thirty percent (30%), and (21%) had never smoked. The quitters were maximum in all the categories of smokers, ex-smokers (26%), smokers (17%), and non-smokers (9%) among mineworkers who had worked in the mines between 10 to 19 years.

8. Results The ex-smokers, smokers and non-smokers were in proportion of about 5:3:2.

13. Conclusion The prevalence of smoking is very high (79%) among ex- mineworkers in the area of Transkei, which is twice higher than general population. Health education with emphasis on the bad effects of tobacco smoke is an important step to curb the widely use smoking habit among ex-mineworkers.
