One of the main people who is running these studies is a guy named Harris Isbel at the Lexington Narcotic Farm. This is where drug addicts could go to get treatment for their addiction. Prisoners could go there as well. And whenever Sidney Gottlieb found a drug that he was interested in, he would basically just give it to Harris Isbel, who could try it out on these prisoners to see how they reacted. And then Isbel would write reports back to Gottlieb.
