The World Conference on Tobacco Control (formerly WCTOH) will take place from 23–25 June 2025, organized by The Union with support from Bloomberg Philanthropies. As the leading global event for tobacco control, it will reunite academics, health professionals, NGOs, and policymakers from over 100 countries, marking the first in-person meeting since 2018.

The Conference offers a vital platform to share successes, best practices, and strengthen efforts to counter the tobacco industry. Professor Guy Marks, President of The Union, welcomed its return as a major step forward for the global tobacco control movement.
