Ohler reveals how methamphetamine, marketed as Pervitin, was widely distributed in Nazi Germany to enhance soldier endurance and fuel the rapid advances of Blitzkrieg warfare, despite the regime’s public anti-drug stance. Hitler’s personal drug use, managed by his physician Dr. Morell, evolved into a complex dependency on opioids, cocaine, and hormonal injections, profoundly impacting his decision-making, especially during critical campaigns like the invasion of the Soviet Union. Contrary to myths, Hitler did not use meth early on but became increasingly reliant on potent stimulants after 1944, contributing to his erratic behavior. The podcast also explores broader themes: the role of drugs in human evolution—what Ohler calls 'Stoned Sapiens'—the intersection of psychedelics with creativity and religion, and covert programs like MKUltra. Additionally, the conversation touches on resistance within Germany, such as the Schulze-Boysen network, and how totalitarian control emerged alongside the suppression of altered states. Ultimately, the discussion reframes historical understanding by showing how psychoactive substances have silently shaped war, power, and civilization itself.
