The problems with Prop 65 go beyond that. The legislation itself effectively made no attempt to define what it means for something to cause cancer. The commission put in charge of enforcement ultimately decided it would mean anything that current scientific evidence suggests has a 1 in 100,000 risk of eventually causing cancer if you are exposed to it for an entire lifetime. Subsequent lawsuits clarified that a substance must be included even if the risk is only proven to exist in non-human animals. Ironically, I never even knew this, but apparently the proposition only exists because Jane Fonda thought it would draw left-leaning voters to the polls to hopefully vote for Tom Bradley over George Deukmejian in the 1986 race for California governor. She and the other proponents didn't even think the proposition itself would pass. But the proposition did pass and Bradley wasn't even elected!
