Introduction: This study evaluated the patterns of smoking cessation at Wave 4 of the Population Assessment of Tobacco and Health (PATH) Study among established cigarette smokers who were also current e-cigarettes users at Wave 3.
Methods: We assessed changes in smoking frequency at Wave 4 among established cigarette and e-cigarette users at Wave 3. The demographics of participants were analyzed as well as e-cigarettes device types, number of cigarettes smoked and time from waking up until the first cigarette. Unadjusted and adjusted odds ratios as well as percentage of discontinuing cigarettes use at Wave 4 were calculated for the different categories of dual users.
Results: Among dual users at Wave 3, 13.1% quit cigarette smoking at Wave 4, whereas half discontinued e-cigarette use and maintained exclusive cigarette smoking. Significant differences in the percentage of smoking cessation were observed across demographic groups - dual users with a bachelor's degree were more likely to quit smoking than dual users who did not finish high school (aOR = 3.06, 95% CI: 1.17-8.00) and smokers aged 25-64 years were less likely to quit smoking than those aged 18-24 years (aOR = 0.49, 95% CI: 0.28-0.86 for smokers aged 25-44 years, and aOR = 0.42, 95% CI: 0.20-0.87 for those aged 45-64). Dual users who smoked more than 15 cigarettes per day were significantly less likely to stop smoking (aOR = 0.38, 95% CI: 0.17-0.88).
Conclusion: E-cigarettes have the potential to aid in smoking cessation. Questions remain as to whether dual use of e-cigarettes and cigarettes should be encouraged as a transitional phase on the path to smoking cessation.

Purpose: Previous research has demonstrated improvements in CT-derived bronchial parameters in the first years after smoking cessation. This study investigates the association between longer smoking cessation duration and bronchial parameters in lung-healthy and lung-unhealthy ex-smokers from the general population.
Materials And Methods: We conducted a cross-sectional analysis using low-dose CT scans of ex-smokers from the general population with at least 10 pack-years from the ImaLife study, a sub study within the Lifelines cohort.

This study evaluates the influence of smoking cessation policies and COVID-19 on the prevalence of smoking among Korean adolescents from 2011 to 2020. Based on the Korea Youth Risk Behavior Web-based Survey, trends in adolescent smoking behaviors were examined, including the impact of cigarette price increases, Pictorial Warning Labels (PWLs), and the onset of COVID-19. We used joinpoint regression analysis to discern annual changes in the prevalence of adolescent smokers.

Background: Smoking rates in the UK have declined steadily over the past decades, masking considerable inequalities, as little change has been observed among people with a mental health condition. This trial sought to assess the feasibility and acceptability of supplying an electronic cigarette (e-cigarette) starter kit for smoking cessation as an adjunct to usual care for smoking cessation, to smokers with a mental health condition treated in the community, to inform a future effectiveness trial.
Methods: This randomised controlled feasibility trial, conducted March-December 2022, compared the intervention (e-cigarette starter kit with a corresponding information leaflet and demonstration with Very Brief Advice) with a 'usual care' control at 1-month follow-up.

The smoking cessation drug cytisine exerts neuroprotection in substantia nigra pars compacta (SNc) dopaminergic (DA) neurons of female but not male 6-hydroxydopamine (6-OHDA) lesioned parkinsonian mice. To address the important question of whether circulating 17β-estradiol mediates this effect, we employ two mouse models aimed at depleting systemically circulating 17β-estradiol: (i) bilateral ovariectomy (OVX), and (ii) aromatase inhibition with systemically administered letrozole. In both models, depleting systemically circulating 17β-estradiol in female 6-OHDA lesioned parkinsonian mice results in the loss of cytisine-mediated neuroprotection as measured using apomorphine-induced contralateral rotations and SNc DA neurodegeneration.
