Annual change in global smoking

(A) Changes in current and former smoking prevalence over time, age standardised. (B) Number of current and former smokers over time for all ages. Estimates for 1990–2019 were obtained from GBD 2021 for (A) and (B). The solid lines in (A) and (B) indicate the mean estimate, whereas the shaded areas reflect the 95% uncertainty interval. (C) Decomposition of forecasted change in number of smokers from 2023 to 2050 due to population ageing, population growth, and changes in the prevalence rate among current and former smokers. The grey dashed vertical line in (A) and (B) indicates 2022 (the first forecast year). The black dots in (C) indicate the overall percentage change in the number of smokers from 2023 to 2050.
