The Nazis presented themselves as warriors against moral degeneracy. Yet the entire Third Reich was permeated with drugs: cocaine, heroin, morphine and, most of all, methamphetamines, or crystal meth, used by everyone from factory workers to housewives, and crucial to troops' resilience - even partly explaining German victory in 1940. The promiscuous use of drugs at the very highest levels also impaired and confused decision-making, with Hitler and his entourage taking refuge in potentially lethal cocktails of stimulants administered by the physician Dr Morell as the war turned against Germany.
