More like every five on BB. 2015 and 2016 that I know of.
It wasn’t just the Germans, though,and not just WW2. I’ll quote my earlier comment:
From Wikipedia: “During World War II, amphetamine and methamphetamine were used extensively by both the Allied and Axis forces for their stimulant and performance-enhancing effects.”
Also: “Amphetamine was given to Allied bomber pilots during World War II to sustain them by fighting off fatigue and enhancing focus during long flights. During the Persian Gulf War, amphetamine became the drug of choice for American bomber pilots, being used on a voluntary basis by roughly half of U.S. Air Force pilots.The Tarnak Farm incident, in which an American F-16 pilot killed several friendly Canadian soldiers on the ground [in Afghanistan], was blamed by the pilot on his use of amphetamine.”
I knew a man who joined the Canadian Army as a teenager at the end of WW2, and was training to go to the Pacific when the war ended. He described being given a pill that the recruits were told would eliminate the need for food. I’ve always assumed that was amphetamine or a similar stimulant.
Soldiers have been returning from war as addicts for a long time. From the Wikipedia article on morphine:
“…its extensive use during the American Civil War allegedly resulted in over 400,000 sufferers from the “soldier’s disease” of morphine addiction.”
