Simon Chaitowitz: Why I Take Animal-Tested Drugs One of my doctors has told me to get my affairs in order, which is why I'm writing this column. I want to explain why someone who takes so many animal-tested drugs is opposed to animal research. I have full-blown leukemia and the chemotherapy I'm taking doesn't seem to be working all that well. And even if it does kick into high gear soon, it's not a cure, only a brief delay of the disease's progression. One way or another, my odds aren't good.
