Or, at least that was popular with some. Seems Hitler's speed was cocaine. From an interview with Norman Ohler, author of the relatively new book, Blitzed.
Meanwhile, in Berlin, Hitler was experiencing his own unreality, with his only ally in the world his podgy, insecure personal physician, Dr Morell. In the late 20s, Morell had grown a thriving private practice in Berlin, his reputation built on the modish vitamin injections he liked to give his patients. He met Hitler after he treated Heinrich Hoffman, the official Reich photographer, and sensing an opportunity quickly ingratiated himself with the Führer, who had long suffered from severe intestinal pains. Morell prescribed Mutaflor, a preparation based on bacteria, and when his patient’s condition – Patient A, as Hitler was thereafter known – began to improve, their codependent relationship began. Both were isolated. Hitler increasingly trusted no one but his doctor, while Morell relied solely on the Führer for his position.
When Hitler fell seriously ill in 1941, however, the vitamin injections that Morell had counted on no longer had any effect – and so he began to ramp things up. First, there were injections of animal hormones for this most notorious of vegetarians, and then a whole series of ever stronger medications until, at last, he began giving him a “wonder drug” called Eukodal, a designer opiate and close cousin of heroin whose chief characteristic was its potential to induce a euphoric state in the patient (today it is known as oxycodone). It wasn’t long before Hitler was receiving injections of Eukodal several times a day. Eventually he would combine it with twice daily doses of the high grade cocaine he had originally been prescribed for a problem with his ears, following an explosion in the Wolf’s Lair, his bunker on the eastern front.
