# Spotlight Summary

Korean researchers examined whether smokers’ intentions to quit differ depending on whether they use conventional cigarettes, heated tobacco products (HTPs), or both. Using data from over 40,000 adults, the study classified tobacco users into detailed subgroups based on their lifetime and current use patterns to better understand how these different products affect quitting behavior. Understanding quit intentions across tobacco use types is critical for public health planning, as it can help tailor cessation interventions and inform policies about newer products like HTPs that are growing in popularity but have unclear long-term implications for smoking cessation rates.

Summary
This study examined how state laws that prevent local governments from enacting their own youth tobacco access regulations affect cigarette purchasing patterns and spending across US counties from 2004-2021. The research provides evidence on whether state preemption of local tobacco control laws influences cigarette consumption and expenditures, offering insights into the effectiveness of local versus state-level regulatory approaches to youth tobacco access.
Policy—Taxation/Pricing
Minh Hoang Van, Anh Tran Tuan, Tuyet Hanh Tran Thi et al.. Tobacco use insights. 2026. doi:10.1002/app5.222
Summary
This research examined how cigarette affordability affects smoking intensity in Vietnam between 2020 and 2024, a period when rapid economic growth has outpaced increases in excise taxes. The study compared the relative impact of absolute cigarette expenditure versus affordability measures on smoking consumption patterns across different demographic groups, providing evidence on whether pricing policies are keeping pace with economic changes to reduce tobacco use.
Satybaldiyeva Nora, Schleicher Nina C, Prochaska Judith J et al.. Addiction (Abingdon, England). 2026 Aug. doi:10.1111/add.70569
Summary
This study examined price comparisons between oral nicotine pouches (ONPs), particularly the leading Zyn brand, and cigarettes in the United States, where ONP sales tripled between 2021 and 2024. Understanding the relative pricing of these products is important for public health policy, as price differences may influence whether smokers switch to ONPs or how accessible these newer nicotine products are compared to traditional cigarettes.
Protection—Secondhand/Thirdhand Smoke
Larcombe Alexander N. Pediatric research. 2026 Aug. doi:10.20517/jeea.2024.27
Summary
E-cigarette aerosol leaves residues on indoor surfaces (third-hand e-cigarette aerosol) that can be re-emitted, ingested, or absorbed, posing potential risks to infants and children. Despite the common perception that e-cigarettes are safer than tobacco and acceptable to use around children, these residual deposits may pose developmental risks to the lungs of young people. The findings suggest that ‘vape-free’ environments should be treated with similar precaution as smoke-free environments to protect children’s respiratory health.

Summary
Researchers examined how nicotine affects gene expression in the mouse brain when kainate receptors are activated, finding that nicotine selectively blocked the production of certain genes (Arc and junB) while leaving others (c-fos and egr1) unchanged. This suggests nicotine has complex, selective effects on how different genes are expressed in brain cells, which may help explain some of nicotine’s neurological impacts at the molecular level.

Summary
Researchers examined whether the ASSIST screening tool’s standard cutoff scores for identifying moderate cannabis use risk are appropriate for U.S. military veterans with chronic pain who use cannabis medically. The study aimed to establish more suitable risk thresholds for this specific population, as the established cutoffs may not accurately reflect problematic use patterns among medical cannabis users.
