Our conversation with UCSF psychiatrist, researcher, and educator Dr. Emily Williams delved into her work exploring psychedelic-assisted therapies and her groundbreaking contribution to clinical studies utilizing MDMA for severe PTSD and psilocybin for end-of-life care, as well as her clinical work providing ketamine-assisted treatment for severe depression. Only a couple years out of her psychiatric residency, Dr. Williams represents the HippieDocs 2.0 generation, building on the work of many trailblazing physicians from the heady revolutionary days of the 1960s and 1970s, a movement halted by America's ensuing ‘War on Drugs‘. These interventions, once thought to be radical, are now finding their way into the 21st Century psychiatric tool kit.
