Setting: Tuberculosis (TB) treatment centres in Eastern Nepal.
Objective: To determine smoking cessation rates among TB patients advised to quit.
Design: One intervention and one control centre were studied. At the intervention centre, brief advice about smoking and cessation was given at the start of anti-tuberculosis treatment, and repeated 2 and 5 months later. After 6 months of standard treatment, patients were asked about quitting. Expired air carbon monoxide (CO) was measured in those claiming 6 months of abstinence.
Results: None of the 51 controls achieved 6 months of abstinence, whereas 77 (39%) of the 195 in the intervention group claimed at least 6 months of abstinence. All claims were verified by CO measurement in expired air (95%CI 31.4-47.6, P < 0.0001 for the difference in smoking cessation).
Conclusion: Brief advice on smoking cessation to patients starting anti-tuberculosis treatment in the National Tuberculosis Programme (NTP) setting in Eastern Nepal led to 39% quitting for least 6 months. Our results should encourage randomised trials in smokers with TB in Nepal: if substantiated, smoking cessation advice should become a mandatory component of the NTP.

Lung cancer is the leading cause of cancer-related deaths worldwide, and delayed detection contributes to poor outcomes. Primary care plays a crucial role in early diagnosis, but detecting lung cancer early remains challenging for general practitioners (GPs). Therefore, the aim of this scoping review was to identify optimal strategies and pathways for lung cancer screening (LCS) in primary care settings globally.

Introduction: In women, smoking during pregnancy and the postpartum period has important consequences for maternal and infant health, and interventions to assist smoking cessation during this period are essential. Although smoking has been associated with the presence of mental health problems, few studies addressing the factors associated with perinatal smoking have examined the role of stress. The aim of this review was to identify the relationships between the presence of stress and smoking during pregnancy and the postpartum period.

Background: Previous research has identified differences in e-cigarette use and socioeconomic factors between different racial groups However, there is little research examining specific risk factors contributing to the racial differences.
Objective: This study sought to identify racial disparities in e-cigarette use and to determine risk factors that help explain these differences.
Methods: We used Wave 5 (2018-2019) of the Adult Population Assessment of Tobacco and Health (PATH) Study.

Smoking is highly prevalent and persistent among people with mental illness, but implementation of smoking cessation care by mental healthcare professionals (MHCPs) is lagging behind. This study took a broad approach to understanding implementation of stop smoking support (SSS) by MHCPs (N = 220 for main analyses), incorporating background characteristics, psychosocial factors, client factors, and organizational/environmental factors. Variable selection was based on previous work and the Consolidated Framework for Implementation Research.

Aim: In February 2024, the Aotearoa New Zealand Government repealed legislation to mandate very low nicotine cigarettes (VLNCs), greatly reduce the number of tobacco retailers and disallow sale of tobacco products to people born after 2008 (smokefree generation). We investigated acceptability and likely impacts of these measures among people who smoke or who recently (≤2 years) quit smoking.
Method: We analysed data from 1,230 participants from Wave 3 (conducted in late 2020 and early 2021) and 615 participants from Wave 3.
