Thats why the government is so keen on stopping illegal drugs. The war on drugs is largely funded by drugs companies that want ALL the business of killing people via drugs to themselves.
Actually Doctors and hospitals are the biggest killer of people in the US, they kill 10 times more people than guns, so where are the anti doctor and hospital groups?
Of course, they might save a few people too. I'd even wager that they overall loss/save ratio might lean more towards saving. Of course, the same could probably be said about guns. More people's lives are saved because of guns than taken. But then again the doctor statistic is always fun to use.
