History

Historical Context

In 1991 the EPA classified glyphosate as non-carcinogenic, and the 1996 New York lawsuit forced Monsanto to drop false “practically non-toxic” ads. After Bayer bought Monsanto in 2018, it faced tens of thousands of cancer claims and settled more than 100,000 of them for about $9.6 billion. The 2024 Supreme Court 7-2 ruling upheld federal preemption of state warning suits, preserving that regulatory gap.
