Well, I have. You're trying to equate the plight of drug users/dealers who consciously decide to flaunt the law and end up in jail or dead for their mistakes with the plight of the millions of entirely innocent victims of malaria, who could have been saved if DDT weren't banned.
The two situations are entirely different, and it's a small mind indeed that will not or cannot appreciate the difference.
People in jail for drugs had a choice in the matter. That makes all the difference in the world. Your moral equivalence argument just won't fly.
