During the early Blitzkrieg campaigns of World War II, German soldiers were issued Pervitin, a powerful methamphetamine-based stimulant often described as a “miracle pill.” The drug helped troops stay awake for extraordinarily long periods, sometimes reportedly up to 72 hours, while suppressing fatigue and boosting their confidence as they pushed across Europe. But the temporary surge in energy came with dangerous consequences. Prolonged use and sleep deprivation could trigger hallucinations, paranoia, aggression, and severe mood swings. By 1941, German military doctors were raising concerns about the drug’s harmful effects, including psychological disturbances that could compromise soldiers’ judgment and performance. Although Germany’s rapid military advances were primarily driven by tactics, coordination, and mechanized warfare, stimulants played a role in helping exhausted troops maintain their relentless pace. Behind the lightning-fast offensives was a disturbing reality: some soldiers were pushing their bodies beyond normal human limits with the help of methamphetamine.
