The National Tobacco Cessation Collaborative (NTCC) was formed in June 2005 to improve the public's health by increasing successful cessation among tobacco users in the U.S. and Canada through collaborative efforts of committed organizations. Collaborative members represent major organizations that fund research, program, and policy initiatives related to tobacco cessation, as well as other organizations with a vested interest in tobacco cessation.
