Death by Medicine
Peer-reviewed research has shown that 100,000 Americans die each year from adverse prescription drug reactions. An equal amount die from medical errors. In the past three years, the number of Americans who died from these two causes outnumbers deaths from terrorism by about 200 to 1. Why aren't we concerned about this? Why is their no presidential commission interviewing people in congress about this?
This issue is compounded by the fact that more and more research is funded by industry these days and less is supported independent government funding. Industry funded research is much more likely to reach favorable conclusions about a particular drug than non-industry research. The FDA doesn't do it's own research, it depends upon other published work, so as the industry co-ops the scientific community, we're actually seeing drugs on the market that have been promoted instead of tested.
