Health: What We Don’t Know

What does long term mean?

How long after exposure to pollution can it take for health effects to surface?

How long after exposure to a new drug can it take for risk factors to be come evident.

A new study from Chile says that cancers due to arsenic exposure can occur forty years after the exposure.

That’s more than 10x longer than a normal clinical trial, much less the fast lane for new drug testing that the FDA under Trump is now promoting.

So if you don’t think environmental pollution matters, just wait, your time may not have arrived . . . yet.
