The problem is people don't know how to quantify the risk, including myself.

However there a number of people who panic! And the panicky people have loud voices. They treat everything like DDT or asbestos. That's not to say that caution is not warranted. It is, but take it easy, the frogs aren't turning gay and people are living longer, so long as they don't get hooked on addictive drugs, including tobacco, alcohol, MJ, amphetamines, etc.
