Lead water pipes were used in the UK until 1970. Lead paint was banned in 1992. Not sure what that says about hallucinating in the UK.
It is interesting to note that, as lead exposure was reduced, levels of violent crime decreased.

Proponents of the lead–crime hypothesis argue that the removal of lead additives from motor fuel, and the consequent decline in children's lead exposure, explains the fall in crime rates in the United States beginning in the 1990s. — link

When the amount of lead in the environment increased, Nevin showed a corresponding rise in violent crime two decades later. And when the amount of lead in the environment fell, violent crime also tracked down - again about 20 years later. — link
Either unhealthy environments of sorts are predicated of crime in the USA, or lead exposure is necessary and sufficient cause of criminality in later life.
I can't imagine how statisticians could screen out all the independent variables, without doing a longitudinal study on lab animals. Vivisection is unethical therefore it's safer and more ethical to presume not only lead exposure is bad but also all public utilities and commercial products should be of the highest possible standards.
Considering the social world is far from perfect, can anyone tell me if and how statisticians screen out all possible variables from a retrospective analysis?
Ideas of God invariably predicate of God that nothing bad can be predicated of God. This fact leaves ideas of God impregnable to all and any contributory causes of God.
