Strengthening Global substance Use Epidemiology: The Role of the WHO Technical Advisory Group
The World Health organization (WHO) relies on expert guidance to effectively address the complex challenges posed by alcohol and drug use worldwide. Central to this effort is the Technical Advisory Group on Alcohol and Drug Epidemiology (TAG-ADE), a body dedicated to bolstering the scientific foundation for public health interventions. The TAG-ADE provides crucial technical expertise to the WHO Secretariat concerning the epidemiology of substance use and the associated health and societal harms.
Enhancing Data Quality and Global Estimates
A primary focus of the TAG-ADE is the continuous refinement of WHO’s estimates regarding the prevalence of alcohol and drug use across global populations. This includes a detailed assessment of the disease burden directly attributable to substance use – quantifying the impact on morbidity and mortality. Accurate data is paramount for informed policy-making and resource allocation. For example, recent data indicates that alcohol-related liver disease is increasing in younger adults in several high-income countries WHO Alcohol, highlighting the need for targeted prevention strategies. The group also concentrates on improving the methodologies used to measure prevention and treatment coverage for substance use disorders, ensuring a clearer understanding of service gaps and areas for improvement.
Strategic Direction and Collaborative Research
The July 2025 meeting of the TAG-ADE marks the beginning of its 2025-2027 term. This initial meeting will be pivotal in solidifying the group’s composition, confirming leadership roles, and reaffirming its core mandate and strategic objectives. A key agenda item will be a review of recent advancements in comparative risk assessment (CRA) methodologies. CRA allows for a systematic evaluation of the relative contribution of various risk factors – including alcohol and drug use – to overall disease burden.
Advancing the International Research Agenda
Beyond data refinement and methodological improvements, the TAG-ADE plays a vital role in shaping the international research agenda for substance use and related health conditions. This involves identifying critical knowledge gaps,prioritizing research areas,and fostering collaboration among researchers globally. Current research priorities include investigating the neurobiological mechanisms underlying addiction, evaluating the effectiveness of novel treatment approaches (such as digital therapeutics), and understanding the social determinants of substance use.
