Investigative database
Mapping Big Tobacco's
networks of influence
A documented map of the companies, organisations, campaigns, events and individuals connected to the world's five largest tobacco corporations — built from academic, journalistic and primary sources.
Tobacco Nexus is an independent investigative database. The database maps the networks of companies, organisations, campaigns, events and individuals documented as connected to Philip Morris International, British American Tobacco, Japan Tobacco International, Imperial Brands and Altria — the five corporations that control the vast majority of global tobacco sales. An overview of each company is available on this site.
An entity is included when at least one documented connection ties it to a tobacco manufacturer — through ownership, employment, financial contributions, contracted services, sponsorships, scientific collaboration, or conference participation. The nature and depth of each connection vary considerably. Each card describes the specific documented link.
Inclusion does not imply wrongdoing. Readers are encouraged to consult the cited primary sources directly before drawing conclusions.
