Our government has been involve in several scandals over medical "trials and experiments." One of the more famous is the Tuskegee syphilis experiment. This was where a government sponsored research team took 399 African American men who had syphilis and told the they had a blood disorder and did not treat them for syphilis to watch the progression of the syphilis. There are several others like this. The way the FDA operates is not much better. We set up clinical trials to test new treatments. Often these drugs or procedures have already been tested and proven in other countries. The so called scientific method sets up 2 groups those that get the real meds or procedure and those that do not. These are almost always done on the sickness folks with no other hope yet we only give the drug or procedure to half. This is cruel and IMO no better than what we did to those in the Tuskegee.If it is for the common cold or some minor thing it might be OK. However, these are folks that are going (in most cases ) die and the trial gives them hope. If one has stage 3 or 4 lung cancer we know from experience the mortality rate. We don't need a "control group". This is done not to have good science or help the helpless but IMO to help the drug company sell in many cases near worthless drugs. See if the folks getting the treatment live a few months longer than those that don't it is declared a success. Then we have know cures like adult stem cells from your own body that has proven to cure arthritis . It is standard procedure by vets for dogs, horses etc. It is also proven effective in other counties on humans and is becoming standard care. Yet we haven't even started trials in the US. Why? I believe because it would make to many drugs useless and put to many orthopedic surgeons out of work. I have ranted long enough but we need a better system for medical research in the US.
