Prop 65 threshold for level of harm is two orders of magnitude below any effect level (not the harm level, effect) which I’d argue creates so many false notices of harm that most people simply ignore them eroding trust in the government.
Indeed the level is so low that under the law, the daily recommended dose of vitamin A for pregnant women would need a notice saying it caused birth defects. They had to ignore the law and add a caveat for vitamin A since not taking it causes birth defects.
If they didn’t pick an arbitrary threshold, ignoring scientific consensus on what dose makes the poison, it would have been far more successful.
