In California, there is a law that basically everywhere (e.g. all apartment complexes) must have a sign that specifies that the compounds used on site can cause cancer or birth defects or whatever. But because the signs are pervasive, they are basically useless. This feels kind of like that.
A fishing sinker made from lead is pretty obvious when you see that warning. There's only one ingredient, lead, and it's obvious why it's harmful. But when you buy a complex product that says "this product contains chemicals known by the State of California to cause cancer or birth defects", the first thing I want to know is what the chemical is, the second is where it is in the product, and the third is why it's there. Nothing in the warnings makes manufacturers tell you any useful information.
