Phillip Morris is apparently not as complacent about the WHO’s tobacco control treaty as it appears publicly, according to MedPage Today and Reuters.

The treaty was adopted in 2003, and made it possible to push for things like smoke-free bars. It has persuaded dozens of nations to increase tobacco taxes, pass laws restricting smoking in public places, and increase the size of health warnings on cigarette packs. Some 90% of countries signed on, though the US is a notable holdout.

Reuters published thousands of documents related to the investigation in a repository it’s calling The Phillip Morris Files.
