I proposed doing a basic human study, using a double-blind method to find out the most basic questions about marijuana. First of all, I wanted to find out whether you could study it in the laboratory, how it affected basic vital functions and basic psychomotor functions. This was a big step to take. There was no legal mechanism for getting marijuana for research. There were many different federal and state agencies that were involved. A lawyer who was very interested in marijuana legal issues bet me that I would never be able to obtain permission to get marijuana to do human research. The attitude of the school was, they were very upset, the Human Subjects Committee. Because one of our experimental designs was that we wanted to give marijuana to people who never had it before, because we felt that expectation played an enormous role in determining the effects of marijuana. And people who had previously used it had expectations of what it would do. The Human Subjects Committee of the school took the position it would be unethical to expose people to marijuana who had never been exposed to it. We ended up doing the research at Boston University School of Medicine, because Harvard wouldn’t let it be done on their premises. And there was a lot of contention here, I mean, there were a lot of negotiations with many agencies and bureaucracies.
