I'm not sure this map is trustworthy given CA's propensity to label everything under the sun as unsafe. I bought a turning signal to fix my grandpa's boat trailer and it had the famous CA cancer advisory. Crying wolf, man.<p>How about this: is the turning signal more likely to give you cancer than living with an indoor smoker? Unlikely. And yet living with secondhand smoke is associated with a ~20% increase in risk, i.e. from ~6% lifetime risk to ~7.2% lifetime risk
