Amphetamine

“Thus, by World War II, amphetamine in tablet form was finding commercial success and gaining credibility as a prescription psychiatric medication (the first ‘antidepressant’) . . . The war years did nothing to diminish the drug’s growth in popularity. . . The US military also supplied Benzedrine to servicemen during the war, mainly as 5-mg tablets, for routine use in aviation, as a general medical supply, and in emergency kits” [as did the British military] (Rasmussen IV, 975).
