Hitler’s propaganda stressed the importance of keeping fit and abstaining from drink and tobacco to keep the Aryan race strong and pure. But in reality his soldiers were taking addictive and damaging chemicals to make them fight longer and more fiercely. A study of medicines used by the Third Reich exposes how Nazi doctors and officers issued recruits with pills to help them fight longer and without rest. The German army’s drug of choice as it overran Poland, Holland, Belgium and France was Pervitin – pills made from methamphetamine, commonly known today as crystal meth.
