Tobacco-attributable mortality and disease burden in India: a descriptive analysis of Global Burden of Disease 2023 estimates for 1990 and 2023.
Tobacco use remains a major contributor to mortality and disability in India. This study assessed tobacco-attributable mortality and disability-adjusted life-years (DALYs) in India in 1990 and 2023, with comparisons by sex, age group and type of tobacco exposure.

India.
Tobacco-attributable deaths and DALYs were assessed by sex, age group and type of tobacco exposure, including smoking, chewing tobacco and secondhand smoke. Absolute numbers and age-standardised rates were compared between 1990 and 2023.
Tobacco-attributable deaths increased by 54.7%, from 745.74 thousand in 1990 to 1 153.98 thousand in 2023, while DALYs increased by 15.1%, from 27.3 to 31.4 million. In contrast, age-standardised death and DALY rates declined by 39.8% and 47.8%, respectively. Smoking remained the leading contributor (738.8 thousand deaths; 19.78 million DALYs in 2023), particularly among males. Chewing tobacco showed the largest increase (deaths +153.7%; DALYs +124.8%). Secondhand smoke remained substantial, particularly among females (325.63 thousand deaths), though its DALY burden declined by 10.8%. The burden shifted towards non-communicable diseases, with chronic obstructive pulmonary disease, ischaemic heart disease and stroke as leading contributors in 2023.
Despite declines in age-standardised rates, the overall burden of tobacco in India remains substantial. The differing patterns across smoking, chewing tobacco and secondhand smoke highlight the need for comprehensive and targeted tobacco-control strategies.
