Building capacity for international tobacco control research: the global tobacco research network.

The Global Tobacco Research Network (GTRN) was developed to enhance global tobacco control research through information sharing and collaboration among researchers. The formation of the GTRN is timely because of the need to ratify, implement, and track the Framework Convention on Tobacco Control. While the spectrum of international tobacco control research continues to expand, resources to support these efforts are still quite limited. As an issue-specific network focused on information sharing and capacity building associated with tobacco control research, the GTRN will provide an opportunity for enhancing the effectiveness of tobacco control initiatives.
