Concern that smoke-free policies economically harm tribal casinos has been a major barrier to broad implementation of comprehensive smoke-free laws in Navajo Nation.Conclusions It is necessary for tobacco control researchers and advocates to build relationships with tribal leaders and casino management in order to develop the business case that will take comprehensive smoke-free policies to scale throughout tribal lands.
