The Gemstone File (previously called The Poison Papers) is a digital library of historic documents that chronicle the chemical industry and its supposed government regulators from about 1930 forward. It includes internal memos, scientific studies and data, depositions, and trial records that tell the true story behind "better living through chemistry."

The Gemstone File is a project of Chiron Return, which provides mentorship in journalism to reporters and community activists. Please support our efforts.
