Timothy Leary started down that path, then just proceeded through most every pharmaceutical there ever was just trying to find a new kick and trip his balls off. His actions ended up discrediting the entire endeavor.
Agreed. His biography was interesting though. He lamented that in all his years in Psychiatry the basic statistics hadn't changed at all. One third of patients got better, one third got worse, and one third stayed the same. I think he just gave up on science and decided to have a good time.
