From
www.americanchemistry.com: "Chlorine chemistry is essential to more than 93 percent of prescription pharmaceuticals sold in the U.S. These include critical drugs used to treat high cholesterol, stomach ulcers, anemia, cancer, epilepsy and depression. For U.S. and Canadian consumers, the total benefit of chlorine chemistry in pharmaceuticals is estimated to be $450 billion per year."
Being an organochloride does not automatically make it bad.
*sigh*
Nevermind. I'm sure going back to the caves will work out fine.
