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.

Youth mental health is a growing global crisis, with most mental health conditions beginning before the age of 25. Young people today face increasing stress from poverty, academic and social pressure, bullying (including online), climate anxiety, and uncertainty about the future, while mental health services struggle to keep up with demand. Although governments play a critical role, philanthropic investment can help strengthen the social determinants of youth mental health and support prevention at scale. Despite growing global attention, including commitments through the UN Sustainable...

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...

Opioid use during pregnancy and the postpartum period is increasing in the United States, yet many pregnant and parenting people face serious barriers to accessing effective treatment and supportive services. These barriers arise from fragmented systems such as healthcare, health insurance, child welfare, childcare, and the criminal justice system. This study uses in-depth interviews with healthcare providers, treatment leaders, local government officials, and pregnant and parenting people in a mid-Atlantic state to explore access to medication for opioid use disorder (MOUD), key treatment...

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...
