Tobacco Use and Smoking Cessation Interventions
Summary
Tobacco use remains a leading preventable cause of morbidity and mortality worldwide, with combustible cigarettes accounting for the vast majority of tobacco‐related disease. Smoking cessation interventions encompass a spectrum of approaches, including pharmacotherapy (nicotine replacement therapy, varenicline, bupropion), behavioural support (brief advice, counselling, digital applications), harm‐reduction strategies (electronic cigarettes, smokeless products) and population‐level policies (taxation, smoke‐free legislation, health warnings). Integration of individual and policy measures under frameworks such as the WHO Framework Convention on Tobacco Control and MPOWER has driven declines in prevalence in many regions, yet demographic forces and novel products continue to challenge progress. Recent advances highlight the importance of tailored support, real‐world effectiveness studies and sustained political commitment to accelerate reductions in both active and passive smoking.
Research from Nature Portfolio
A comprehensive synthesis of secondhand smoke exposure has applied a quantitative risk‐function methodology to nine health outcomes, revealing that even passive inhalation elevates risks of ischaemic heart disease, stroke, type 2 diabetes and lung cancer by at least 1–8 percent. The analysis graded the strength of each association and underscored important evidence gaps for respiratory and breast diseases. By delivering probabilistic estimates that account for uncertainty, this work reinforces the imperative for combined public health policies and education initiatives to curb both active smoking and involuntary exposure in diverse settings.
