This is an interesting doctor and an interesting Ted Talk. It speaks about how medications through trial processes can be 'played with' and that there is a wide spread issue with this type of practice. I thought I would post it in case anyone was interested. If you head to the website alltrials.net you will notice a petition that you can sign if you are concerned about the issues brought up in the video and/or posted on the website.
