The effects of Methamphetamin (more commonly known as Crystal Meth) are well known to people today. What is not so well known is that soldiers in World War 2 were actually given meth to keep awake during battle.
For the Germans it was often handed out as “Pervitin”, which went under the nickname “Panzerschokolade” (tank chocolate). The Allies were not innocent in this regard either. Many Allied bombers were given meth for long flights. As one would imagine, it did not go well. The Nazis and the Allies have tremendous problems with troops on meth because they were getting very irritable and aggressive even towards their own people.
