Ah crud...in years past I have bought large bags of Mexican candy from Amazon...and subsequently eaten all of it. :( Does anyone know if there is a test that can tell "historical" levels of lead? It sticks around in the blood right? So if I get a regular lead test will it account for any historical consumption? Has there also been any research into devising a test to determine if IQ has fallen due to lead poisoning? I guess I don't see a way for this data to be collected after the fact?

Eating a few bags of candy isn't going to do it. It's going to take years and years of constant exposure. People in this thread need to calm down. Even if you did lose 5 IQ points, it's not like Flowers For Algernon here... No one would even notice. The only reason we can is due to large sample sizes over decades and decades.
