A comprehensive study led by Hitotsubashi University identifies tax hikes, smoke-free legislation and anti-smoking campaigns as the most effective measures to reduce smoking rates. The findings provide critical insights for policymakers worldwide.
A new study by researchers at Hitotsubashi University has revealed that tax increases, smoke-free legislation and anti-smoking campaigns are among the most effective tools in reducing smoking prevalence and consumption. The findings, published in the journal Nature Human Behavior, offer crucial insights for policymakers in the ongoing battle against tobacco use.
Tobacco remains a formidable global health challenge. Despite numerous national and international efforts, smoking continues to be a leading cause of premature death. Its impact is widespread, significantly elevating risks for non-communicable diseases like cardiovascular disease, cancer, chronic respiratory conditions and diabetes — diseases that account for nearly 75% of annual global deaths.
The research team’s comprehensive review involved a systematic analysis of 476 studies focused on real-world, population-level tobacco control strategies.
“Our study provides a detailed overview of the impact of various population-level interventions to curb smoking,” lead author Shamima Akter, an assistant professor at Hitotsubashi University, said in a news release. “Based on the available evidence, anti-tobacco campaigns, smoke-free legislation, health warnings and tax increases are the most effective strategies for reducing smoking,”
The study’s results show that tax hikes, smoke-free laws and public anti-smoking campaigns significantly reduced smoking rates and cigarette consumption.
These measures also boosted quit rates, attempts and intentions.
Additionally, health warnings on cigarette packaging and flavor bans further contributed to higher smoking cessation rates and reduced e-cigarette use.
