Competing Interests

The authors do not consider these competing interests, but in the interest of full transparency Dr. Glantz declares the following: Dr. Glantz holds two research grants related to tobacco from the National Cancer Institute (one of which, CA-87472, supported this work), an endowed chair as American Legacy Distinguished Professor in Tobacco Control, and, during the time some of the work on this project was completed, an unrelated grant from University of California Tobacco Related Diseases Research Program. Dr. Glantz also administers an endowment from the American Legacy Foundation, which supports the UCSF Center for Tobacco Control Research and Education, which Dr. Glantz directs, and the Legacy Tobacco Documents Library. He also has the William Cahan Endowment provided by the Flight Attendant Medical Research Institute. None of these organizations played any role in the preparation of this paper or the decision to submit it for publication. All other authors have declared that no competing interests exist.
