Background: Namibia is typical of low-income and middle-income countries with growing tobacco use, but with limited capacity to impose comprehensive tobacco control legislation. Despite initiating dialogue on national tobacco control policy in 1991, the country took nearly 20 years to pass the Tobacco Products Control Act., Objective: To use Namibia as a case study to illustrate challenges faced by low-income countries working to forward tobacco control legislation., Method: Face-to-face and telephonic interviews were conducted with 13 bureaucrats and advocates currently or previously engaged in tobacco-related work in Namibia. Tobacco-related news articles from national newspapers were examined., Results: The constitutional obligation of the government to promote public health laid the foundation for Namibia's tobacco control policy. Staff capacity constraints greatly delayed the passing of tobacco control legislation. It is unclear what influence the tobacco industry's involvement as a stakeholder had on policy; however, in at least one instance, the tobacco industry actively misled government. Namibia's ratification of the Framework Convention on Tobacco Control was instrumental in passing legislation that meets most provisions of the international treaty. The media have generally played a supportive role in pushing the government to pass tobacco control legislation., Conclusions: The fact that Namibia was able to pass fairly comprehensive tobacco control legislation with such meagre resources is commendable. The government must now implement the regulations that make the legislation effective. Tobacco control progress in low-income and middle-income nations can be encouraged through use of the media and improved staff and legal capacity within health ministries., (Published by the BMJ Publishing Group Limited.

Long-term success for any tobacco endgame is contingent not only on acquiring political will, but also on sustaining it over a long period of time, perhaps even for decades. Future cohorts of public health professionals with knowledge of tobacco issues are therefore needed to carry on with the endgame strategy (should early attempts fail) and to keep tobacco control salient after an endgame strategy has initially been implemented. The endgame itself offers a unique pedagogical opportunity that could revive interest in tobacco control at schools of public health--an important first step in cultivating the future advocacy base for a tobacco endgame.

Background: Smokeless tobacco use is becoming an increasingly important public health issue in the US and may influence cigarette smoking behavior. Systematic information on transitions between smokeless tobacco and cigarette use in the US is limited. Methods: We conducted a systematic review of published literature on transitions between smokeless tobacco and cigarette use in the US. We searched PubMed, Web of Science and EbscoHost databases for all published articles from January 2000 to March 2014 that presented estimates of transitions in US youth and adult study populations over time between at least one of the following tobacco use states: exclusive cigarette smoking, exclusive smokeless tobacco use, dual use of both products, and use of neither product. We excluded non-English language studies, studies published before 2000, clinical trials, controlled cessation programs, and clinical studies or evaluations of smokeless tobacco cessation programs. Results: The review identified six studies on US populations published since 2000 with longitudinal data on some or all of the transitions that users can undergo between smokeless tobacco and cigarette use. There was considerable heterogeneity across studies in design and tobacco use definitions. Despite these differences, the existing data indicate that switching behaviors from exclusive smoking to exclusive smokeless tobacco use are limited (adults: 0%-1.4%, adolescents: 0.8%-3.8%) but may be more common from exclusive smokeless tobacco use to exclusive smoking (adults: 0.9%-26.6%, adolescents: 16.6%-25.5%). Among adults, exclusive cigarette smoking was generally stable and consistent (79.7% to 87.6%) over follow-up across studies but less stable in adolescents (46.8%-78.7%). Exclusive smokeless tobacco use was less stable than exclusive cigarette smoking over time (adults: 59.4%-76.6%, adolescents: 26.2%-44.8%). Conclusion: This review provides published estimates of the proportions of adults and adolescents transitioning between tobacco use categories from the most recently available studies on longitudinal transitions between smokeless tobacco and cigarettes in the US. These data can be used to track tobacco use behaviors and evaluate their effect on public health; however, the data for these studies were generally collected more than a decade ago. Additional research including nationally representative longitudinal estimates using consistent definitions and designs, would improve understanding of current tobacco transition behaviors.
