[The tobacco industry's internal documents and smoking prevention in Spain]

A 1998 agreement between several states in the USA and the tobacco industry made millions of pages of internal documents available to the public. Many of these documents contain information that the industry would have preferred to keep confidential. Systematic review of these internal documents constitutes a valuable resource for international tobacco control, since they are available on the Internet and can be accessed from anywhere in the world. These documents provide relevant and useful information to antismoking activists and researchers. To facilitate their use, the present article presents the electronic archives of the tobacco industry's documents, describes methods for conducting searches, and identifies the documents with information on the industry's tactics for manipulating Spanish politics and society for its own commercial interests during the 1970s, 1980s, and 1990s.
