For how we live.
The first dedicated Global Burden of Disease analysis of passive smoking finds exposure falling in relative terms but stuck in absolute numbers, and still causing 1.66 million deaths a year — most from heart disease.
A Global Burden of Disease 2023 analysis counts 241 million users worldwide, concentrated in south Asia, with a rising burden of stroke and oral cancer even as prevalence has barely moved.
US guidelines recommend a one-time ultrasound for men aged 65 to 75 who ever smoked, and advise against it for most women. The split turns on who actually benefits from finding a silent bulge in the aorta.
A Global Burden of Disease 2023 study counts 1,102,794 incident tracheal, bronchus and lung cancers in Asians aged 60 and over in 2023, with ageing populations set to sustain the burden even as rates fall.
One ultrasound scan for abdominal aortic aneurysm cuts AAA-related deaths in older men who ever smoked — but not all-cause mortality. The evidence is almost entirely about men, which is why the recommendation is too.
A descriptive study using WHO modelled estimates for 2022 put current cigarette use between 1.7% in Ghana and 18.2% in Seychelles, with the male-female gap reaching 36.4 points in Lesotho.
New guidelines set how the program, launched in July 2025, screens people aged 50 to 70 with a 30 pack-year smoking history using two-yearly low-dose CT scans.
E-cigarettes are the tobacco product US teenagers use most, and youth use has fallen from its peak. The clearest documented harm is that teens who vape are several times more likely to start smoking cigarettes.
Smoking is the leading modifiable cause, and the most common presenting sign is blood in the urine. There is no recommended screening test, which makes that sign the thing to act on.
A 4,066-person survey series across Funafuti and the outer islands links second-hand smoke exposure — reported by 61% of participants — to obesity and elevated STOP-Bang scores.
The disease is lethal largely because it is found late. That is also why guidelines recommend against screening the general public — the evidence says it would do more harm than good.
Cross-sectional studies from the country's south and east report about a third of respondents vaping, with attitudes — not knowledge — the factor most strongly linked to use.
Two large randomised trials found low-dose CT screening cut lung-cancer deaths in heavy smokers. The eligibility rules are narrow, and the reason is written into the evidence.
A large US analysis attributed 42 percent of cancer cases to modifiable risk factors. One factor dwarfs all the others, and it is not diet.
An econometric analysis of the 2019 European Health Interview Survey prices smoking-attributable inpatient and daycare hospitalisation across the EU — deliberately excluding every other kind of care.
