The National Conference on Tobacco or Health (NCTOH) is one of the largest, long-standing gatherings for top United States tobacco control professionals. The convening attracts a diversity of public health professionals committed to best practices and policies to reduce tobacco use—the leading preventable cause of disease and death in the United States. 

The National Network of Public Health Institutes (NNPHI) works alongside a steering committee of agencies, foundations, practice organizations, and program committees to leverage its extensive convening expertise and widespread network of public health institutes, training centers, and dozens of key stakeholders to enhance both programmatic content and overall experience.
