This is the untold story of how Nazi experiments with psychedelics influenced CIA research and the War on Drugs. From covert mind control programs to experiments with 'truth serums', we trace the connection between the Third Reich's sinister scientific experiments and later US drug policy.

To explain this wild post-war history, Dan is joined by the bestselling historian Norman Ohler, author of 'Tripped: Nazi Germany, the CIA, and the Dawn of the Psychedelic Age'.

Produced by James Hickmann and edited by Dougal Patmore.
