Season 5 Finale- The Development of PCP and Ketamine

Ketamine has found wide uses since the 1960s: As a painkiller, an anesthetic, a street drug consumed at raves, and -- now -- considered by many to be an exciting new treatment for depression. We explore how ketamine was developed here in Detroit, at the Parke-Davis pharmaceutical company, with help from a Wayne State University chemistry professor, and later tested at the now-closed Lafayette Clinic facility in Detroit.
