The History of Psychedelic Research

As research into psychedelics and their medical uses makes a comeback, scientists are having to deal with the legacy – both scientific and social – of a 40-year near total freeze on psychedelic research. In this episode, we speak with three experts about the early rise and fall of psychedelics in western science and culture, how the mystical and often vague language of the 60s and 70s still pervades research today and what it’s like to actually run clinical trials using psilocybin.

Featuring Robin Carhart-Harris at the University of California, San Francisco in the US; Wayne Hall, at the University of Queensland in Australia; and Josjan Zijlmans at Vrije Universiteit Amsterdam in the Netherlands.
