Methamphetamine, was developed by the Nazis after seeing how effective the amphetamine Benzedrine was for the American team in the '36 Olympics. Under the name Pervitin, the Nazis used the drug throughout WWII, it enabled them to keep fighting for days on end. Blitzkrieg was partly a byproduct of meth. This is also part of the reason why German troops found it so easy to murder large numbers of unarmed people during Barbarossa in the name of heartless Nazi ideology - meth-heads lack empathy.
