AI Article Synopsis
- The study looked at how smoking quit rates in Korea changed after two new rules: raising taxes on tobacco and requiring graphic warnings on cigarette packs.
- It found that smokers who had lower cigarette consumption (1-14 per day) or wanted to quit were more likely to stop smoking after these rules were introduced.
- A bigger tax increase made it even more likely for heavier smokers (15 or more per day) to quit, but the graphic warnings didn't have a strong effect on encouraging more people to stop smoking.
Article Abstract
Background: This study examined whether changes in quitting smoking differed according to smokers' cigarettes consumed per day (CPD) and intention to quit (ITQ) after the introduction of two tobacco control measures in Korea, a tobacco tax increase in 2015 and pictorial cigarette pack warnings (PCW) in 2016.
Methods: We utilized data from the Korea Welfare Panel Study from 2013 to 2017, an interval that was divided into four periods (2013-2014, 2014-2015, 2015-2016, and 2016-2017). We examined differential changes in quitting smoking by smokers' CPD and ITQ using a generalized estimating equation model.
Results: Smokers with 1-14 CPD or an ITQ were more likely to quit smoking in each period. However, when compared to the pre-policy period (2013-2014), smokers with 15 or more CPD and those with an ITQ had a higher risk ratio of quitting smoking in all study periods. In stratified analyses, when the tobacco excise tax was increased, the risk ratios of quitting smoking increased in most subgroups, especially smokers with 15 or more CPD or an ITQ. The increased risk ratio of 15 or more CPD smokers subgroup sustained afterward. However, after the introduction of PCW, there were no significant changes from the previous period in most subgroups.
Conclusions: The addictive nature of tobacco and the type of tobacco control policies jointly contributed to changes in quitting smoking among Korean smokers. Tobacco control policies, particularly substantial tobacco tax increase, acted as a cue-to-action for quitting smoking among more dependent smokers.

Background: The KOTAK program is a national public health initiative in Malaysian primary and secondary schools aimed at reducing youth smoking through school dental services. This study evaluated its effectiveness in Seremban, Negeri Sembilan, Malaysia.
Objectives: 1) To determine the percentage of schoolchildren who quit smoking through the KOTAK program; 2) To identify factors associated with quitting smoking in the program.
Background: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare interstitial lung disease primarily affecting young to middle-aged smokers. While traditionally linked to tobacco use, there is growing evidence that cannabis use may contribute to PLCH.
Methods: We present a case of a 52-year-old male with PLCH associated with heavy cannabis use.

Background: Smoking rates have declined markedly in Australia over time; however, lesbian, bisexual and queer (LBQ) women continue to smoke at higher rates than heterosexual women. Understanding the factors influencing smoking in this population is crucial for developing targeted cessation interventions and other supports.
Methods: Experiences of and motivations for smoking among 42 LBQ cisgender and transgender women and non-binary people in Australia who currently or previously smoked were explored through semi-structured interviews.
Differences in the effectiveness of individual-level smoking cessation interventions by socioeconomic status.

Background: People from lower socioeconomic groups are more likely to smoke and less likely to succeed in achieving abstinence, making tobacco smoking a leading driver of health inequalities. Contextual factors affecting subpopulations may moderate the efficacy of individual-level smoking cessation interventions. It is not known whether any intervention performs differently across socioeconomically-diverse populations and contexts.

Introduction: Ecological momentary assessment (EMA) is popular in smoking research to study time-varying processes and design just-in-time personalised cessation interventions. Yet, research examining the psychometric properties of EMA and user experiences with EMA protocols is lacking. We conducted a mixed-methods study to test the EMA component of a mobile intervention for middle to late-aged adolescents (16-20 years) who smoke cigarettes at least weekly.
