Tobacco Use
Tobacco use killed roughly 8 million people in 2024 — among the largest preventable causes of death. Adult smoking prevalence has declined from 33% globally (2000) to 22% (2024) under the WHO Framework Convention on Tobacco Control and national tax/restriction packages. The decline is fastest in high-income countries; smoking persists at high levels in much of Asia, Eastern Europe, and parts of the Middle East.
Key insights
Smoking has declined faster than most public-health analysts predicted
The 2003 WHO Framework Convention on Tobacco Control (FCTC) created the policy template: high excise taxes, smoke-free indoor laws, graphic health warnings, advertising bans, plain packaging, cessation support. Where fully implemented, smoking prevalence has fallen 0.5–1pp per year sustainably. Australia is the policy leader and has the lowest prevalence among OECD economies.
Tobacco-use geography is shifting
Almost all of the world's smokers live in low- and middle-income countries. China alone accounts for ~30% (310M smokers). India 12% (100M+). Indonesia 65M. Russia 35M. Most of the recent absolute increase in smoker numbers comes from population growth in regions where prevalence has fallen slowly. The Big-4 multinational tobacco companies have shifted marketing to these markets as high-income markets contract.
Vaping has displaced some cigarette use
E-cigarette adoption is now well-established in many high-income markets — 7–10% of adults in the UK, US and Sweden use them. Cessation evidence suggests they help some smokers quit but recruit some non-smokers (especially adolescents) to nicotine use. Health authorities are split on net public-health effect; the UK is the most permissive, Australia and India among the most restrictive.

Methodology & caveats
Defining 'current smoker'
Most prevalence figures use 'current daily smoker' as the definition. Including occasional smokers (less than daily) raises rates by 3–5pp in most countries. Self-reported smoking systematically understates true prevalence by 5–15% — biomarker-based studies (urinary cotinine) suggest under-reporting is worst among women in countries where smoking is socially disapproved.
Tobacco vs nicotine
Cigarettes and cigars deliver nicotine alongside thousands of combustion products. E-cigarettes deliver nicotine without combustion. Smokeless tobacco (Swedish snus, Indian gutka) delivers nicotine and varying levels of carcinogens. Public-health framing has historically treated 'tobacco use' as the unit; harm-reduction advocates argue for separating combustion (clearly harmful) from nicotine delivery (addictive but less acutely harmful).
Time lags
Lung cancer rates lag smoking trends by 20–30 years because of the long induction period. US lung cancer mortality is now falling fast in men (smoking peaked in the 1950s) and starting to fall in women (smoking peaked in the 1970s). Countries where smoking is still rising will see lung cancer rates rise for decades after prevalence eventually declines.
