Patterns and distribution of tobacco consumption in India: cross sectional multilevel evidence from the 1998-9 national family health survey.
To investigate the demographic, socioeconomic, and geographical distribution of tobacco consumption in India. ⋯ The distribution of tobacco consumption is likely to maintain, and perhaps increase, the current considerable socioeconomic differentials in health in India.
