Secondhand smoke (SHS) continues to be a major global health risk, contributing to cardiovascular diseases, metabolic disorders, and respiratory illnesses. Using data from the Global Burden of Disease 2021 study across 204 countries, this analysis examined the burden of SHS exposure through Disability-Adjusted Life Years (DALYs) across different socio-demographic regions. The findings show notable sex and regional disparities: ischemic heart disease caused a higher burden among males, while diabetes and stroke affected females more. COPD had the highest burden in lower-middle SDI regions...

Background

Thousands of people have lost their lives due to overdose-related fatalities linked to the potent synthetic opioid epidemic, as mortalities increase annually. British Columbia (B.C.) Canada has been an exception, where the population not only has more liberal views on illegal drugs, but overdose death numbers have reduced for the first time in recent months. The reduction of overdose deaths in BC and liberal views have taken place in conjunction with the Vancouver Area Network of Drug Users’ (VANDU) advocacy growth over the past two decades.

Smokeless tobacco use is very common in South Asia, but there is limited evidence on effective ways to help users quit. This randomized study evaluated a face-to-face behavioural support program (BISCA) compared with self-help materials among adult smokeless tobacco users attending a dental hospital. One hundred participants who were motivated to quit were included. The BISCA group showed better outcomes for most tobacco withdrawal symptoms and slightly higher quit rates than the self-help group, though the difference was not statistically significant. Given the high prevalence of smokeless...

The Mental Health or Nurses and Doctors (MeND) survey, conducted by WHO Regional Office for Europe under a contribution agreement with the European Commission, aimed to explore the mental health, well-being and working conditions of doctors and nurses in the 27 European Union countries plus Iceland and Norway.

The survey was disseminated from October 2024 to April 2025 across all 29 countries, obtaining 122 048 responses, of which 90 171 were valid. The findings indicated a high prevalence of mental health conditions and unsafe working conditions – including violence, extended working hours...

The ESPAD report presents the results of the eighth data-collection wave, which took place in 2024, and marks an impressive 30 years of data collection by this long-standing collaboration. More than 113 000 15- to 16-year-old students from 37 countries, including 25 EU Member States, took part. Since 1995, over 800 000 students have contributed, making ESPAD the most extensive harmonised data collection on substance use and risk behaviours in Europe, and the largest cross- national research project on adolescent substance use worldwide.

The Canadian Centre on Substance Use and Addiction (CCSA) transforms complex data into insights that reflect real human experiences. Every aspect of the Canadian Substance Use Cost and Harms (CSUCH) project represents individuals with lived or living experience of substance use, along with their families, workplaces, and communities.

A new resource highlights these journeys and the human cost of substance use through illustrated stories from people with lived experience and their families. The illustrations cover three key areas of the CSUCH project: healthcare, lost productivity, and...

Introduction

Prevention science is interdisciplinary, drawing upon multiple fields of research and practice to develop integrated knowledge. A challenge facing the field is the proliferation of different terms with the same meaning, and of terms with different meanings. This can create confusion in communication, affect evaluation standards, and ultimately also affect the implementation of preventive interventions. Contributing to the development of evidence standards for preventive interventions, this article describes the process and results of interdisciplinary prevention terminology...

In this reading list, we provide resources to help engage our members with the latest knowledge, tools, and case studies on quality standards in substance use disorder treatment. These materials highlight international frameworks, research-backed practices, and country-level initiatives designed to improve access, strengthen systems, and ensure safe, ethical, and effective care. 

Together, they offer a practical foundation for policy-makers, service providers, researchers, and healthcare professionals to reflect on what “quality” means in treatment and how to achieve it across diverse...

The 2025 Annual Report to the Parliament on Drug Addictions in Italy offers a comprehensive overview of the current drug addiction landscape. Despite a slight decline in youth drug use for the first time since 2018, the report highlights ongoing challenges, particularly with substances like cocaine, synthetic opioids, and high-potency cannabis derivatives. Law enforcement and judicial efforts remain strong, and Italy continues to be a key collaborator in global anti-drug initiatives, particularly with countries in South America and the Indo-Pacific region.

The report also emphasizes the...

A large U.S. study has found that some children and teens who start using alcohol, cannabis, or nicotine at an early age already show differences in their brains before they ever try any substance. This challenges the common belief that drug use causes brain changes—it suggests that some young people may already be more vulnerable due to personality traits like curiosity or risk-taking, or because of early life stress or genetics.

The good news is that these early traits can be addressed. A school-based program in Canada helped teens better understand and manage their personalities—and five...
