This is the first major study to be completed on how smoking causes death in India. It compared the smoking habits of 43,000 men who had died of various diseases in the late 1990s with the habits of 35,000 living men. More than 4000 of these deaths were from TB, but if the smokers had had the same low risks as non-smokers there would have been fewer than 2000 TB deaths. Few women in south India smoke, so the study was only of men.
