ISAM Global Experts Network (ISAM GEN): Expert Elicitation with Addiction Medicine Professionals

An international network connecting experts to advance research, education, and innovation in addiction science

What is ISAM Global Expert Network (ISAM-GEN)?

ISAM-GEN is an initiative of ISAM designed to extend the boundaries of addiction medicine by connecting experts worldwide within a structured international network for expert elicitation. Its foundations date back to the early days of the COVID-19 pandemic in 2020, when an initial international survey was launched as a rapid response to gather reliable, real-time insights from experts on how the field was adapting to the crisis. Building on this early effort, ISAM-GEN evolved into a global expert infrastructure anchored within ISAM, with the aim of enabling valid and reliable expert elicitation, as well as consensus-building, across diverse sub-disciplines of addiction science.

What are ISAM-GEN’s Missions and Objectives?

  • Advance high-quality, collaborative addiction research
  • Promote addiction knowledge translation and innovation
  • Foster cross-regional and cross-disciplinary collaboration
  • Enable valid and reliable expert elicitation and consensus-building on emerging and complex issues
  • Support early-career and emerging experts globally

Why Is a Global Expert Network Needed in Addiction Science?

Expert opinion is a vital source of evidence in addiction science, particularly when empirical data are limited, the issues under consideration are complex, or rapid synthesis is required to inform timely interventions and policy responses. The evolving and multifaceted nature of substance use disorders and behavioral addictions underscores the need for global networks capable of identifying emerging challenges, integrating cross-national perspectives, and generating informed consensus in areas of uncertainty or disagreement.

In this context, and in the wake of the COVID-19 pandemic, an ISAM working group conducted a global survey in 2020 involving 185 experts in addiction science from 77 countries to assess changes in addiction patterns and national service provision. The strong engagement and informative outcomes of this initiative demonstrated the value of sustained international collaboration and led ISAM to establish a permanent global expert network.

The ISAM Global Expert Network (ISAM-GEN) builds on this foundation by developing a structured, ISAM-anchored global infrastructure that enables valid and reliable expert elicitation and consensus-building across the diverse sub-disciplines of addiction science.

How Is ISAM-GEN Growing Around the World?

Since early 2023, ISAM-GEN has steadily expanded as a global platform for collaboration among addiction experts. In 2023, the network included 354 experts from 76 countries. By 2024, this number had grown to 443 experts from 102 countries, and as of the end of 2025, ISAM-GEN comprises 514 experts from 110 countries worldwide.

The growth of the network is illustrated in three world maps below showing the distribution of experts across 2023-2025. Complementing this, the expert recruitment diagram depicts the structured process of invitations, selection, and onboarding, demonstrating how ISAM-GEN has expanded systematically while ensuring diverse and balanced representation across regions and sub-disciplines.

 

Beyond individual members, ISAM-GEN maintains a database of over 50 national addiction medicine societies, further strengthening its international reach.

Looking ahead, the network aims to expand by connecting treatment centers and addiction facilities worldwide, fostering collaborative research, knowledge exchange, and the translation of evidence into practice.

What Are the Currently Running Projects Within ISAM-GEN?

ISAM-GEN currently hosts six active working groups, each focused on developing global surveys to explore a variety of topics, including comorbid psychiatric disorders, emerging addictive behaviors, and novel therapeutic approaches for patients with substance use disorders.

1. Problematic Use of Internet (PUI) Working Group

It is conducting a systematic review and a global survey, which covers PUI case scenarios; societal and organizational impact of PUI; country-level health responses; and severity assessment of distinct PUI domains (shopping, gaming, gambling, pornography, social media). The survey was distributed to ISAM-GEN societies and organizations, with data collected from mid-2024 to the end of 2024. Both the systematic review and the global survey are now under review.
